Detection Method of Photoelectric Axis Stability of Autocollimation Angle of Light Tube

Abstract

The invention relates to a method for detecting the stability of an optical electric axis of an auto-collimation angular measurement light pipe, aiming at providing a method for detecting the stability of an optical electric axis of an auto-collimation angular measurement light pipe. The method herein is realized by an angular measurement system of an auto-collimation light pipe, and is free from operation space and working environment. The method comprises the following steps: (1) building a datum object on a protection glass; (2) determining effective reflective area of the datum object; (3) setting the auto-collimation light pipe to have two working modes; (4) when the auto-collimation light pipe is under self-examination mode, starting the use of a parameter 1, detecting a return image of the datum object; under a working mode, starting the use of a parameter 2, detecting return images of other object prisms; (5) upon rollout, preserving the datum object angular information measured under self-examination mode by the auto-collimation light pipe as constants and recording the datum object angular information; (6) conducting no adjustment on the position of the datum object after the rollout, and remeasuring once adjustment is conducted.

Description

technical field [0001] The invention relates to the field of photoelectric measurement, in particular to a method for detecting the stability of the photoelectric axis of a self-collimation angle light tube. Background technique [0002] When the autocollimated goniometry light tube is used in the field of aiming and angle measurement, its photoelectric axis usually represents the azimuth reference, and its requirement is that the photoelectric axis should remain stable under various environmental conditions; therefore, how to detect the autocollimated goniometry light The stability of the photoelectric axis of the tube becomes a problem to be studied. [0003] At present, the relative measurement method is usually used to detect the stability of the photoelectric axis. The specific method is to establish a reference mirror on the same installation base of the autocollimation goniophotometer, which can be a rectangular prism or a plane mirror; The included angle with the r...
