Description
Technical Field
The present application relates to the field of optical testing, and more particularly to optical power testing devices.
Background
The optical power refers to the work of light in a unit time, and the optical power of a light source is an important parameter influencing the performance of the light source. For example, when the optical power of the optical transmitter module is small, the energy of the optical signal transmitted by the optical transmitter module is weak, which affects the transmission distance of the optical signal; when the optical power of the light emitting module is large, the current flowing through the light emitting module will be large, which affects the service life of the light source. Therefore, in the actual industry, it is often necessary to test the optical power of the light source.
At present, the light source is moved to the entrance pupil of the optical power meter mainly by a manual moving mode, so that the optical power of the light source is tested by the optical power meter. However, the preset distance between the light source and the optical power meter is small, and the requirement on positioning accuracy is high, so that the difficulty of optical power test is increased.
On the one hand, even if the position of the light source is repeatedly debugged, the precision is still difficult to guarantee. That is to say, the mode of realizing the light source location through manual removal makes the positioning error of light source great, and efficiency of software testing is lower. Particularly, when the light sources to be detected are arranged in a dot matrix, the position of each sub-light source arranged in the dot matrix needs to be repeatedly debugged, and the difficulty of the optical power test is obviously improved.
On the other hand, the preset distance between the light source and the optical power meter is small, the positioning accuracy requirement is high, and the light source and the optical power meter are easy to collide in the process of manually moving the light source. That is, the manner in which the manual movement achieves positioning of the light source results in a greater risk of collision of the light source with the optical power meter, and the structure of the light source and the optical power meter is easily damaged.
Therefore, a new optical power testing scheme is desired to achieve relatively accurate positioning between the light source and the optical power meter.

Summary of the application
As described above, at present, the light source is moved to the entrance pupil of the optical power meter mainly by means of manual movement, so as to test the optical power of the light source through the optical power meter. However, the preset distance between the light source and the optical power meter is small, and the requirement on positioning accuracy is high, so that the difficulty of optical power test is increased.
On one hand, the positioning error of the light source is larger and the testing efficiency is lower by a mode of realizing the positioning of the light source through manual movement. Particularly, when the light sources to be detected are arranged in a dot matrix, the position of each sub-light source arranged in the dot matrix needs to be repeatedly debugged, and the difficulty of the optical power test is obviously improved. On the other hand, the way of manually moving to position the light source results in a high risk of collision between the light source and the optical power meter, and the structure of the light source and the optical power meter is easily damaged.
Based on this, the relative position of the light source to be detected and the optical power meter can be adjusted through the position adjuster, so that the positioning accuracy between the light source to be detected and the optical power meter is improved. Specifically, firstly, a displacement sensor is used for determining relative position relation data between the light source to be detected or the optical power meter and a preset reference surface, and then, based on the relative position relation data between the light source to be detected or the optical power meter and the preset reference surface, the position of the light source to be detected and/or the optical power meter is adjusted through the position adjuster, so that relatively high positioning accuracy is achieved between the light source to be detected and the optical power meter.
Based on this, the present application proposes an optical power testing apparatus, which includes: an optical power meter; the displacement sensor is configured to measure relative position relation data between the light source to be detected or the optical power meter and a preset reference surface; and a positioner communicably connected to the displacement sensor, wherein the optical power meter is mounted to the positioner, wherein the positioner is configured to adjust relative positions of the optical power meter and the detection light source in a first direction and a second direction based on the relative positional relationship data; wherein the optical power meter is suitable for measuring the optical power value of the light source to be detected after the relative position of the optical power meter and the detection light source is adjusted through the positioner.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Exemplary optical power test device
As shown in fig. 1, an optical power testing apparatus 100 according to an embodiment of the present application is illustrated, the optical power testing apparatus 100 adjusts the relative position between a light source 200 to be detected and an optical power meter 10 through a positioner 30 to improve the positioning accuracy between the light source 200 to be detected and the optical power meter 10, so as to facilitate the optical power meter 10 to perform an optical power test on the light source 200 to be detected.
Specifically, the optical power test apparatus 100 includes an optical power meter 10, a displacement sensor 20, and a positioner 30. The displacement sensor 20 is configured to measure relative position relationship data between the light source 200 to be detected or the optical power meter 10 and a preset reference plane, so that the position adjuster 30 adjusts the relative position of the light source 200 to be detected and the optical power meter 10 based on the relative position relationship data between the light source 200 to be detected and the preset reference plane. It should be understood that the predetermined reference plane may be a predetermined plane without a solid body, that is, in a specific example, the predetermined reference plane is not a solid element and is not a component of the optical power testing apparatus 100.
In a specific example, the relative position relationship data between the light source 200 to be detected and the preset reference plane may be implemented as a height deviation between the light source 200 to be detected and the preset reference plane, and of course, the relative position relationship data may also be implemented as other values, for example, a distance between the light source 200 to be detected and the preset reference plane, which is not limited in this application.
The optical power meter 10 is configured to measure an optical power value of the light source 200 to be detected (e.g., an emission unit of a TOF camera module). In particular, the optical power meter 10 has an entrance pupil, and when the optical power value of the light source 200 to be detected is measured by the optical power meter 10, the light source is aligned with the entrance pupil of the optical power meter 10, i.e. the optical power meter 10 is held in the optical path of the light source.
Accordingly, the optical power meter 10 is mounted to the positioner 30, the positioner 30 is communicably connected to the displacement sensor 20, and the positioner 30 is configured to adjust the relative positions of the optical power meter 10 and the light source 200 to be detected based on the relative positional relationship data. In a specific example, the position adjuster 30 may adjust the relative positions of the light source 200 to be detected and the optical power meter 10 in two directions, so as to ensure the positioning accuracy between the light source 200 to be detected and the optical power meter 10, and improve the flexibility of the optical power testing apparatus 100, so that the optical power testing apparatus 100 is suitable for testing the optical powers of different light sources. Specifically, the position adjuster 30 includes a first adjusting component 31 and a second adjusting component 32, wherein the first adjusting component 31 is configured to adjust a relative position of the light source to be detected and the optical power meter 10 in a first direction, and the second adjusting component 32 is configured to adjust a relative position of the light source to be detected 200 and the optical power meter 10 in a second direction.
In the present example, the first direction is a horizontal direction, i.e., a direction parallel to the entrance pupil of the optical power meter 10. The second direction is a vertical direction, i.e. a direction perpendicular to the entrance pupil of the optical power meter 10.
It should be noted that the position adjuster 30 can quickly adjust the relative position of the light source 200 to be detected in the optical power, that is, can realize relatively quick positioning between the light source 200 to be detected and the optical power meter 10, and improve the testing efficiency.
In particular, in one specific example, the position adjuster 30 can adjust not only the position of the light source 200 to be detected, but also the position of the optical power meter 10. Correspondingly, the first adjusting assembly 31 includes at least a first adjusting arm 311 and a first mounting table 312 mounted on the first adjusting arm 311, wherein the first mounting table 312 is adapted to mount the light source 200 to be detected, and the first adjusting arm 311 is used for adjusting the motion track of the light source 200 to be detected. The second adjusting assembly 32 includes at least a second adjusting arm 321 and a second mounting platform 322 mounted on the second adjusting arm 321, wherein the optical power meter 10 is mounted on the second mounting platform 322, and the second adjusting arm 321 is used for adjusting a motion trajectory of the optical power meter 10.
Accordingly, the first adjusting arm 311 is used for adjusting the motion track of the light source to be detected 200 in the first direction, so as to adjust the relative position of the light source to be detected 200 and the optical power meter 10 in the first direction. The second adjusting arm 321 is configured to adjust a movement track of the optical power meter 10 in the second direction, so as to adjust a relative position between the light source 200 to be detected and the optical power meter 10 in the second direction.
Specifically, the first mounting platform 312 is slidably mounted to the at least one first adjustment arm 311, and the second mounting platform 322 is slidably mounted to the at least one second adjustment arm 321. It should be understood that the first mounting table 312 (the second mounting table 322) may also be mounted to the at least one first adjusting arm 311 (the at least one second adjusting arm 321) by other methods, for example, the first mounting table 312 (the second mounting table 322) may be pivotally mounted to the at least one first adjusting arm 311 (the at least one second adjusting arm 321), which is not limited by the present application.
More specifically, in order to measure the optical power value of the light source 200 to be detected by the optical power meter 10, the optical power meter 10 needs to be held on the optical path of the light source 200 to be detected. Accordingly, the first adjustment arm 311 has a first region 301, wherein the first region 301 is aligned with the optical power meter 10, so that the optical power meter 10 is held in the optical path of the light source 200 to be detected when the light source 200 to be detected is moved into the first region 301.
Further, the position adjuster 30 adjusts the relative positions of the light source 200 to be detected and the optical power meter 10 based on the relative position relationship data between the light source 200 to be detected and the preset reference plane. Accordingly, the length value of the second adjusting arm 321 for adjusting the relative position of the light source 200 to be detected and the optical power meter 10 in the second direction is greater than or equal to the value of the relative position relationship data between the light source 200 to be detected and the preset reference plane (for example, the height deviation between the light source 200 to be detected and the preset reference plane).
It should be understood that the light source 200 to be detected and the optical power meter 10 can be moved in one direction, but the application is not limited thereto. For example, in another specific example of the present application, the first adjusting assembly 31 includes two first adjusting arms 311, i.e., a first adjusting main arm and a first adjusting sub-arm, and the first mount 312 mounted to the first adjusting main arm. The second adjusting assembly includes two second adjusting arms 321, i.e., a second adjusting main arm and a second adjusting sub arm, and the second mounting table 322 mounted to the first adjusting sub arm. The second adjusting main arm is mounted on the first adjusting main arm, and the second adjusting auxiliary arm is mounted on the first adjusting auxiliary arm.
Accordingly, the first mounting table 312 is adapted to mount the light source 200 to be detected, the first adjusting main arm is used for adjusting the motion track of the light source 200 to be detected in the first direction, and the second adjusting main arm is used for adjusting the motion track of the light source 200 to be detected in the second direction. The optical power meter 10 is mounted on the second mounting platform 322, the first adjusting auxiliary arm is used for adjusting the movement track of the optical power meter 10 in the first direction, and the second adjusting auxiliary arm is used for adjusting the movement track of the optical power meter 10 in the second direction.
Likewise, it should also be understood that the position adjuster 30 can adjust the relative positions of the light source 200 to be detected and the optical power meter 10 by adjusting only the position of the light source 200 to be detected or only the position of the optical power meter 10, which is not limited by the present application. For example, in a specific example of the present application, the first adjusting member includes at least a first adjusting arm 311 and a first mounting table 312 mounted on the first adjusting arm 311, wherein the first mounting table 312 is adapted to mount the light source 200 to be detected, and the first adjusting arm 311 is used for adjusting a moving track of the light source 200 to be detected in the first direction.
The second adjusting assembly 32 includes at least one second adjusting arm 321, wherein the at least one second adjusting arm 321 is mounted on the first adjusting arm 311, and the second adjusting arm 321 is used for adjusting a moving track of the light source 200 to be detected in the second direction.
Accordingly, in a specific example, the process of testing the optical power of the light source 200 to be tested by the optical power testing apparatus 100 is as follows: firstly, determining relative position relation data between the light source 200 to be detected and a preset reference surface through the displacement sensor 20; then, the positioner 30 adjusts the light source 200 to be detected to move to a first preset position in the first direction, so that the optical power meter 10 is located on the optical path of the light source 200 to be detected; then, the optical power meter 10 is adjusted to move to a second preset position in the second direction by the position adjuster 30 to compensate for the height deviation between the light source 200 to be detected and a preset reference plane, that is, the displacement of the optical power meter 10 moving in the second direction is equal to the height deviation between the light source 200 to be detected and the preset reference plane; then, the light source 200 to be detected is turned on, the optical power value of the light source 200 to be detected is measured by the optical power meter 10, and finally, the light source 200 to be detected is turned off. When the light sources 200 to be detected are arranged in a dot matrix, the light power of the sub light sources to be detected of the light sources 200 to be detected is tested according to the above process.
In summary, the optical power testing apparatus 100 is illustrated, and the optical power testing apparatus 100 can achieve relatively precise positioning between the light source 200 to be detected and the optical power meter 10, so that relatively high positioning precision is achieved between the light source 200 to be detected and the optical power meter 10 during the optical power testing process. Moreover, the optical power testing apparatus 100 enables relatively fast positioning between the light source 200 to be tested and the optical power meter 10, so as to improve testing efficiency.
