Description
Technical Field
The invention relates to the field of a biological measuring instrument, in particular to a zero point arm debugging device and method of the biological measuring instrument.
Background
Because the biometer is based on the optical path of the full optical fiber, the radius of the fiber core of the optical fiber is very small, and the reflected light can hardly enter the optical fiber if the reflected light can not return according to the original optical path. It is difficult to ensure the high-precision position relationship of the lenses by only mechanical processing, so a debugging method is urgently needed to accurately adjust the position relationship between the lenses so as to ensure that the incident light can return to the optical fiber according to the original path. In the traditional debugging method, a laser is used as a light source, and the position relation between lenses is judged by observing whether light spots reflected by two paths of reflected light coincide or not. However, the resolution of this method depends on the size of the spot, and the error is large. In addition, the method debugs the four lenses together, and has complex operation, time and labor waste.

The first autocollimator 8 includes a light source 81, a collimator lens 82, a reticle 83, a photosensor 84, and a beam splitter prism 85. In order to ensure that the optical axes of the first autocollimator 8 and the second autocollimator 9 are perpendicular to each other, it is observed at the second autocollimator 9 whether the cross-division line of the first autocollimator 8 coincides with the cross-division line of the second autocollimator 9. If the first autocollimator 8 and the second autocollimator 9 are overlapped, the first autocollimator 8 and the second autocollimator 9 are perpendicular to each other, and if the autocollimator is not overlapped, the position of the first autocollimator 8 is adjusted until the autocollimator is overlapped.
The first autocollimator 8 and the second autocollimator 9 are fixed.

Fixing the zero-point arm part on the four-dimensional adjusting table, attaching the adjusting reflector to the reference surface 11 of the zero-point arm part, as shown in fig. 4, observing the cross division image reflected by the first reflector 4 at the first autocollimator 8, and adjusting the four-dimensional adjusting table to make the cross division line of the first autocollimator 8 coincide with the cross division image reflected by the first reflector 4. To ensure that the collimator optical axis is parallel to the optical axis of the first autocollimator 8,
step three, adjusting the position of the semi-reflecting and semi-transmitting lens 3
Taking down the debugging reflector and attaching the semi-reflecting and semi-transmitting mirror 3 on the zero arm part as shown in figure 5; and observing the cross division line of the first autocollimator 8 at the second autocollimator 9, and adjusting the posture of the half-reflecting and half-transmitting mirror 3 to ensure that the cross division line of the first autocollimator 8 is superposed with the cross division line of the second autocollimator 9 so as to ensure that the half-reflecting and half-transmitting mirror 3 and the optical axis of the collimator form an included angle of 45 degrees.
The half-reflecting and half-transmitting mirror 3 is glued and fixed.
Step four, adjusting the semi-reflecting and semi-transmitting mirror 3 to be parallel to the reflecting surface of the first reflector 4

Observing the cross division images 1 and 2 at the second autocollimator 9, and if the cross division image 1 is superposed with the cross division image 2, indicating that the reflecting surface of the semi-reflecting and semi-transmitting mirror 3 is parallel to the reflecting surface of the first reflector 4; if the cross division image 1 is not coincident with the cross division image 2, the half-reflecting and half-transmitting mirror 3 is not parallel to the reflecting surface of the first reflector 4; the attitude of the first mirror 4 is adjusted so that the cross division images 1, 2 coincide. Thereby ensuring that the transflective mirror 3 is parallel to the first mirror 4.

When the half-reflecting and half-transmitting mirror 3 and the second reflecting mirror 5 are equal to 90 degrees, the cross division image 1 is superposed with the cross division image 2. As shown in fig. 8; when the half-reflecting and half-transmitting mirror 3 and the second reflecting mirror 5 are not equal to 90 degrees, the cross division image 1 and the cross division image 2 are respectively positioned at two sides of the division line. The second reflecting mirror 5 is adjusted in posture so that the cross-divided images 1 and 2 coincide with each other. Thereby ensuring that the second reflecting mirror 5 forms an included angle of 45 degrees with the incident light and forms an included angle of 90 degrees with the half-reflecting and half-transmitting mirror 3.

Step six, adjusting the position of the third reflector 6

By observing the cross division line of the reflected light at the first autocollimator 8 and the cross division line of the first autocollimator 8, if the cross division line does not coincide, it means that the incident light does not return as it is (i.e. the third reflector 6 is not perpendicular to the parallel incident light), the posture of the third reflector 6 is adjusted, so that the cross division line at the first autocollimator 8 coincides with the cross division line of the first autocollimator 8.
