Abstract
The invention relates to a pyramid prism vertical optical dead axle system and a method, comprising a posture adjusting tool, a rotary platform, a picture frame, an inner focusing telescope, a light source, a CCD camera and a PC machine, wherein the posture adjusting tool is arranged on the rotary platform; the CCD camera receives the image point of the inner focusing telescope, and the other end of the CCD camera is connected with the PC machine and fixed in the picture frame through the pyramid prism. Aiming at the technical problem that the existing method for determining the optical axis of the pyramid prism is blank, the vertical optical axis-fixing system of the pyramid prism has a simple structure.
Description
Technical field
The invention belongs to optical centering field, be specifically related to a kind of pyramid mirror vertical type optical dead axle system and method.
Background technology
Prism of corner cube (retroreflecting device) is a kind of inner full-reflection prism manufactured according to critical angle principle, and it is not by the impact of incident angle size, reflected incident light 180 °.In other words, arbitrary is entered to the incident ray of clear aperature, all will be reflected back by former direction efficiently.Early just apply this prism during World War II and find secret airport.As long as pilot loads onto a flashlamp near his forehead and do not need to shoot out from ground light, be positioned at prism on airport by former road Returning beam, thus find airport.In Apollo (Apollo) space travel, prism of corner cube has important application.Moonscape is placed the array of more than 50 prism of corner cubes, then astronomer is by high-power laser beam directive prism array, then returns with telescope reception the light beam penetrating.Laser beam, through by the twice stroke of the earth to the moon, approximately needs time 2.8s, accurately can calculate the distance of the earth to the moon thus.
Prism of corner cube is more and more applied, but does not but have a kind of method can determining the optical axis of prism of corner cube, affects the service precision of prism of corner cube.
Summary of the invention
For the technical matters of existing prism of corner cube optical axis defining method blank, the invention provides a kind of corner prism vertical type optical dead axle system and method.
Technical solution of the present invention:
Corner prism vertical type optical dead axle system, its special character is: comprise pose adjustment frock, revolving dial, picture frame, internal focusing telescope, light source, CCD camera and PC,
Described pose adjustment frock is arranged on revolving dial, the center of described revolving dial is provided with light source hole, and described light source is arranged in light source hole, and described picture frame is fixed on the end face of revolving dial, described internal focusing telescope is arranged on directly over picture frame, is connected with CCD camera; Described CCD camera receives the picture point of internal focusing telescope, and the other end and the PC joint angle cone prism of described CCD camera are fixed in picture frame.
Based on an axis fixation method for corner prism vertical type optical dead axle system, comprise the following steps:
1] internal focusing telescope is accommodated to position, infinite distance, search out the autocollimation reflection picture point of prism of corner cube end face;
2] again internal focusing telescope is accommodated to prism of corner cube vertex position, open light source simultaneously, find the summit transmission picture point of prism of corner cube, light source is exactly the summit transmission picture point of prism of corner cube through picture point formed after prism of corner cube;
3] by step 1], step 2] two picture points finding are presented on PC by CCD camera;
4] pose adjustment frock is adjusted, and two picture points of observing on PC, until the autocollimation reflection picture point of prism of corner cube end face and the movement locus of prism of corner cube summit transmission picture point gradually become stroke roundlet even close to transfixion by drawing great circle, now the optical axis of prism of corner cube and the centre of gyration of rotary table overlap.
The advantage that the present invention has:
1, corner prism vertical type optical dead axle system of the present invention, structure is simple.
2, the present invention adopts optical non-contact metering system completely, find the end face of prism of corner cube and the reflection picture point on summit, the spatial attitude of prism of corner cube is changed by horizontal adjusting mechanism and aligning elevation gear, control the jerk value of two picture points in internal focusing telescope, ensure the registration accuracy of optical axis and revolving dial revolving shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of corner prism vertical type optical dead axle system of the present invention;
Wherein Reference numeral is: 1-pose adjustment frock, 3-revolving dial, 4-prism of corner cube, 5-internal focusing telescope, 6-CCD camera, 7-PC machine, 8-picture frame, 9-power supply, 10-light source.
Embodiment
Prism of corner cube front end face autocollimatic reflection image and prism of corner cube summit transmission picture is found by internal focusing telescope, rotating high-precision rotary working-table and adjusting pose adjustment frock makes two picture points all not rock, and its optical axis can be determined (now prism of corner cube optical axis and high-precision rotary working-table center superposition)
Concrete steps: 1. internal focusing telescope is accommodated to position, infinite distance, search out the autocollimation reflection image of prism of corner cube end face; 2. again internal focusing telescope is accommodated to prism of corner cube vertex position, open light source simultaneously, find the summit transmission picture point of prism of corner cube, light source is exactly the summit transmission picture point of prism of corner cube through picture point formed after prism of corner cube; 3., by level and the pitch attitude of pose adjustment frock adjustment high-precision rotary working-table, control the shaking volume of two picture points, 2 pictures are not rocked; 4. now the optical axis of prism of corner cube can be determined, namely the optical axis of prism of corner cube and the centre of gyration of high-precision rotary working-table overlap.
