Problems solved by technology

This method has the following disadvantages: 1. The installation and adjustment tooling is complicated and cannot be used universally for different photoelectric equipment; 2. The operation process is cumbersome and the efficiency is low; 3. The main mirror is mostly a paraboloid, rather than a spherical surface, and each ring of the parabol

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] A method of using a laser tracker to adjust the optical axis of the primary mirror to be perpendicular to the horizontal axis, such as figure 1 , figure 2 As shown, the method is accomplished through the following steps:

[0022] (1) Set up the laser tracker. The laser tracker should be erected at a position where the horizontal axis and the primary mirror can be measured at the same time, and the laser tracker should be stable and cannot rotate with the horizontal axis.

[0023] (2) Fix the two target balls of the laser tracker at different positions on the horizontal axis, and the two-axis head of the horizontal axis is the most suitable, that is, it is suitable for fixing the target ball and also suitable for observing the target ball.

[0024] (3) Rotate the horizontal axis to drive the target ball, and u...

Abstract

The invention discloses a method for adjusting a primary mirror optical axis to be perpendicularly to a horizontal axis by using a laser tracker and belongs to the technical field of optical installation and adjustment. The method is used for adjusting the primary mirror optical axis of a photoelectric device to be perpendicularly to the horizontal axis and comprises the steps of (1) erecting the laser tracker; (2) fixing two target balls of the laser tracker at different positions of the horizontal axis; (3) rotating the horizontal axis to drive target balls, and using the laser tracker to calibrating the horizontal axis; (4) moving target balls on a primary mirror, and using the laser tracker to calibrating the primary mirror optical axis; and (5) calculating the included angle formed by the primary mirror optical axis and the horizontal axis, and adjusting the primary mirror to incline, so that the primary mirror optical axis is perpendicularly to the horizontal axis. The method solves the problems that existing technologies are complex in tooling, miscellaneous in operation process and large in reference error and is simple to operate, safe and high in efficiency.

Description

technical field [0001] The invention belongs to the field of optical adjustment and relates to a method for adjusting the optical axis of a primary mirror of an optoelectronic device to be perpendicular to a horizontal axis, in particular to a method for adjusting the optical axis of a primary mirror of an optoelectronic device to be perpendicular to a horizontal axis by using a laser tracker. Background technique [0002] Large-scale optoelectronic equipment usually consists of a primary mirror, a secondary mirror, a third mirror, and an imaging system behind it. For high-precision angle measurement, it is necessary to correct the collimation error of the optical system. When the inherent collimation error of the optical system is large, if software is used to eliminate the collimation error, a large residual error will be introduced, which will affect the image quality of the measurement system. Because when the inherent collimation difference of the optical system is larg...
