II orientation of autocollimation theodolite is gone to reading X II, then II orientation of autocollimation theodolite is turned by number X II=1/2 (X3+X4)
180 °, pitching is unlimited.
Further, autocollimation theodolite I is first put in step (3), the pitching of autocollimation theodolite II 4 is according to auto-collimation
Theodolite I 3 adjusts, and I telescope direct of autocollimation theodolite is made to be directed at autocollimation theodolite II, and autocollimation theodolite I orientation is turned
180 °, pitch adjustment value is 180 ° of-Y, is seen on MUT module under test in autocollimation theodolite I and is tested the auto-collimation picture of reflecting mirror, such as
Fruit auto-collimation picture is overlapped with I graduation of autocollimation theodolite, then illustrates that the normal of tested reflecting mirror is parallel with the laser axis of laser,
Otherwise not parallel；Then so that I reversing face of autocollimation theodolite is directed at autocollimation theodolite II, measure again according to the above method, if
Auto-collimation picture is overlapped with I graduation of autocollimation theodolite, then illustrates that the normal of tested reflecting mirror is parallel with the laser axis of laser, no
It is then not parallel, it needs to tested reflecting mirror adjustment, until being overlapped or in zone of reasonableness.
Further, the placement location of autocollimation theodolite I and the placement location of autocollimation theodolite II are being longitudinally formed
Difference in height.
Beneficial effects of the present invention:
1, laser axis and the inspection of tested reflecting mirror normal longitudinal pitch collimation both when larger of laser be can be realized
School.
2, simple, easy, common apparatus can be realized, strong operability.
3, laser is directly observed without eyes, it is highly-safe.
4, calibration precision is high, up to 5 rads.

Specific embodiment
Embodiment cited by the present invention, is merely used to help understand the present invention, should not be construed as protecting model to the present invention
The restriction enclosed for those skilled in the art without departing from the inventive concept of the premise, can also be right
The present invention makes improvements and modifications, these improvement and modification are also fallen into the range of the claims in the present invention protection.
Used device mainly includes working base 1, MUT module under test 2, autocollimation theodolite I 3, autocollimatic when calibration of the present invention
Straight theodolite II 4, two-dimentional auxiliary mirror 5, as shown in Figure 1, being equipped with MUT module under test 2 on working base 1, MUT module under test 2 includes
The tested reflecting mirror 21 placed vertically and horizontal positioned laser 22 are placed with autocollimation theodolite I 3, work before MUT module under test 2
Dress seat 1, MUT module under test 2, autocollimation theodolite I 3 are both placed in same level height, are placed with before autocollimation theodolite I 3 certainly
Theodolite II 4, two-dimentional auxiliary mirror 5 are collimated, autocollimation theodolite II 4, two-dimentional auxiliary mirror 5 are both placed in same level
In height, the placement location of autocollimation theodolite I 3 and the placement location of autocollimation theodolite II 4 are being longitudinally formed difference in height, when
The normal of the laser axis of laser 22 and tested reflecting mirror 21 can be realized the inspection of the two collimation when longitudinal pitch is larger
School.
The present invention is by the collimation calibration one of the laser axis of tested reflecting mirror 21 and laser 22 in MUT module under test 2
It causes.Method and step is as follows:
(1) autocollimation theodolite I 3 and autocollimation theodolite II 4 are removed, the laser of the laser 22 on MUT module under test 2 is made
To the center of two-dimentional auxiliary mirror 5, laser beam is reflected back to MUT module under test 2 for beam instruction, adjusts two-dimentional auxiliary mirror 5
Pitching and orientation are overlapped reflection laser beam hot spot with 2 shoot laser beam hot spot of MUT module under test, at this moment two-dimentional auxiliary mirror 5
Normal be to represent the laser axis of laser 22.
(2) II 4 level-off of autocollimation theodolite is recorded orientation, bowed with it to two-dimentional 5 telescope direct autocollimatic of auxiliary mirror
Reading X1, Y1 are faced upward, then reversing face records orientation, pitching reading X2, Y2, obtain reading X=to two-dimentional 5 autocollimatic of auxiliary mirror
1/2 (X1+X2), Y=1/2 (Y1+Y2)；II 4 orientation of autocollimation theodolite is gone into reading X, then uses telescope direct and reversing face side
Method turns 180 ° in azimuth direction respectively, and record reading X3, X4 obtain reading X II=1/2 (X3+X4), autocollimation theodolite II
4 orientation go to reading X II, then II 4 orientation of autocollimation theodolite is turned 180 °, and pitching is unlimited.
(3) autocollimation theodolite I 3 is placed on as shown in the position Fig. 1, the pitching of autocollimation theodolite II 4 is according to autocollimatic
Straight theodolite I 3 adjusts, and so that I 3 telescope direct of autocollimation theodolite is directed at autocollimation theodolite II 4.By I 3 orientation of autocollimation theodolite
Turn 180 °, pitch adjustment value is 180 ° of-Y.It is seen in autocollimation theodolite I 3 on MUT module under test 2 and is tested the auto-collimation of reflecting mirror 21
Picture illustrates tested 21 normal of reflecting mirror and measured laser light beam if auto-collimation picture is overlapped with I 3 graduation of autocollimation theodolite
In parallel, i.e., the normal of tested reflecting mirror 21 is parallel with the laser axis of laser 22, otherwise not parallel.Then make autocollimation theodolite
I 3 reversing faces are directed at autocollimation theodolite II 4, measure again according to the above method, if auto-collimation picture and I 3 graduation of autocollimation theodolite
It is overlapped, then illustrates that tested 21 normal of reflecting mirror is parallel with measured laser light beam, i.e., the normal and laser 22 of tested reflecting mirror 21
Laser axis it is parallel, it is otherwise not parallel, need to tested 21 adjustment of reflecting mirror, until being overlapped or in zone of reasonableness.
The present invention is the laser axis that laser 22 can be easily realized very much using a kind of optical means and tested reflection
The calibration of the normal parallel of mirror 21.It is especially able to solve when the laser axis of laser 22 and the normal of tested reflecting mirror 21 are being indulged
When larger to spacing, the two cannot be received by the instrument and equipment of same bore simultaneously, lead to not determine parallel sexual intercourse
Problem；Also solve the problems, such as that laser cannot directly be received with general preset lens.In addition, this method can be by the collimation precision of the two
To 5 rads, calibration precision is high for correction.
