In some embodiments, the lens are apochromatic lens.
In the present invention in use, including following detection method:
The efficiency measurement of IFU simple optical fiber
Laser level is determined optical axis with hot spot position sensor first, as needed, position sensor is placed on
Optical path rearmost end, fixed, optical lens required for then placing one by one ensures according to the reading of facula position detector
Each optical element is coaxial, and closely laser is microcobjective (beam expanding lens), for expanding, subsequent camera lens and microcobjective
Collimated light path is formed together, and changes clear aperture with the first diaphragm 4, the system for forming fixed coke ratio with the first lens 5, the coke
It is more consistent than with the incident coke ratio that optical fiber designs in spectrometer, fiber exit end coupled lens, since optical fiber is there are focal ratio degradation,
Fiber exit end calculates the bore and distance (L) of the second diaphragm 7 according to the value of incident coke ratio, and the second diaphragm 7 is placed into phase
Position is answered, for example it is F/5 that optical fiber, which is incident on the coke ratio in spectrometer, then the first diaphragm 4 and the first lens 5 are just made into F/5 system
It unites coupled into optical fibres, after fiber exit end couples lenticule, it is assumed that outgoing coke ratio is F/8, then distance L and the second diaphragm 7
The ratio between bore will be 8, and due to the presence of focal ratio degradation, actual outgoing coke ratio can be less than f/8, and the second diaphragm 7 can block coke ratio
Part light after degeneration, the practical light by the second diaphragm 7 are only our needs, at this moment pass through the with the record of luminous energy 9
The light energy of two diaphragms 7 and the second lens 8 is denoted as Wout, it is assumed that glass transmitance is 95% when light passes through the second lens 8, then leads to
The luminous energy for crossing the second diaphragm 7 is Wout/ 95%, then luminous energy is put into behind the first lens 5 and records projectile energy, as a result remember
For Win, background intensity is then measured again is denoted as Wb
According to formula:
η=(Wout/ 95%-Wb)/(Win-Wb) * 100% (1)
The optical fiber actual efficiency after considering focal ratio degradation can be obtained.Generally central wavelength is usually selected in test
The laser of 405nm, 543.5nm and 633nm are as light source.
The test of IFU fiber array efficiency:
First with the efficiency of the present invention one or several optical fiber of detection, then one end of fiber array using very
Uniform white light illuminates, in conjunction with patent (ZL201621056519.2) detection system (as shown in Figure 3), the one of emergent light
End is fixed on objective table, and (bandwidth can be remote with narrow band filter similar in testing laser device central wavelength for addition in the optical path
It is wider than the bandwidth of laser), and on every imaging fiber to CCD of all testing fiber arrays, then calculate each image
Intensity.Using using 1 optical fiber efficiency of laser testing as reference, it is denoted as ηref, this intensity of root optical fiber on CCD is denoted as
Iref, intensity of the testing fiber on CCD is denoted as It, then reality of the testing fiber in a certain wavelength (laser center wavelength)
Border efficiency etatThen are as follows:
ηt=ηref+It/Iref (2)
HereTest method calculated according to formula (1).
The detection of IFU simple optical fiber focal ratio degradation:
The detection of optical fiber focal ratio degradation utilizes the optical path of Fig. 2, takes one or a few optical fiber as reference optical fiber.It is single in test
When the focal ratio degradation of root optical fiber or several optical fiber, by the optical path of Fig. 2, measuring fiber exit end with CCD distance using CCD is
Spot diameter size d when L, can measure different spot diameter sizes by adjusting L, by being averaged or numerical fitting meter
Practical coke ratio after calculating focal ratio degradation, to improve detection accuracy.
Practical coke ratio after focal ratio degradation is
F/#=L/d (3)
The test of IFU fiber array focal ratio degradation
The focal ratio degradation of an optical fiber is obtained first with the invention patent measurement, is denoted as F/#, the optical fiber is as reference light
Then fibre is consolidated on the objective table of patent (ZL201621056519.2) system end to be measured of fiber array (such as Fig. 3 institute
Show), the other end of fiber array is incident with uniform white light, and CCD is placed at micro- defocus, the white light outgoing of receiving front-end optical fiber
As a result, calculating the half-breadth of testing fiber, it is denoted as Ht, the half-breadth of reference optical fiber is denoted as Href,
The then practical coke ratio F/# ' after IFU optical fiber focal ratio degradation to be measured are as follows:
F/# '=(F/#) * Ht/Href (4)
If fiber array does not couple microlens array, detection method is same as the above-mentioned method.
Focal ratio degradation measurement is carried out for the IFU system of multifiber composition, if measuring meeting by root using above-mentioned method
It devotes a tremendous amount of time and manpower, if equipment combination patent (ZL201621056519.2) the described system for utilizing the present invention to develop
System can the very easily focal ratio degradation of rapid survey whole fiber array optical fiber, fiber array is huger, and number of fibers is more,
The superiority of the detection device can more be embodied.
The gluing uniformity that fiber end face ground/polished degree and microlens array are coupled to fiber array end face detects:
By the optical path as described in Fig. 3, fiber array end to be measured is placed in objective table described in Fig. 3, by light source by optical fiber array
The column other end illuminates, so that fiber array end to be measured is imaged on CCD by Fig. 3 optical path.
Rough judgment method is directly with the naked eye can intuitively to be found out very much by adjusting the contrast of CCD acquisition image
The ground/polished degree and microlens array of the end face of fiber array are coupled to the uniformity of fiber array end face gluing.
The method of high-precision judgement is that the Energy distribution of the image of every optical fiber is handled after being imaged by fiber end face, such as
Fruit Energy distribution is not Gaussian Profile, or have exceeded IFU design tolerance specifically will be according to tolerances in design then to be unqualified
To judge.
Fig. 4 is that microlens array is coupled to the gluing homogeneity test result 1 of IFU fiber array end face, by can be in figure
Find out, gluing uniformity effects are bad.Again gluing measurement result is shown in Fig. 5, and light distribution is more uniform.Counterfeit slit is measured simultaneously
The optical fiber arrangement at end is as a result, as shown in Figure 6 and Figure 7.It is substantially on straight line, meets requirement of experiment.
Integral visual field fiber spectrometer (IFU) optical fiber arrangement accuracy detection, microlens array are coupled to fiber array position
