Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] The specific implementation steps of the method for detecting the stability of the optical axis of the calibration telescope are as follows:
[0022] 1. Adjust the optical axes of the two autocollimators on the same line.
[0023] Such as figure 1 As shown, 1 and 2 are autocollimator A and B respectively, 11 and 12 are eyepiece and objective lens of autocollimator A respectively, 21 and 22 are eyepiece and objective lens of autocollimator B respectively. 3 and 4 are fixed platforms for placing autocollimators 1 and 2 respectively. Autocollimator 1 emits parallel light, can observe the imaging of the crosshair of autocollimator 1 on the reticle through the eyepiece 21 of autocollimator 2, adjust the position of autocollimator 2, make this imaging and The crosshairs of the autocollimator 2 coincide, and at this time the optical axes of...

The invention relates to a calibration telescope optical axis stability detection method. According to the method, the optical axes of two autocollimators are adjusted so as to be made located on thesame straight line, a tested calibration telescope is arranged on a multi-dimensional adjustable platform; the platform is adjusted so that the optical axis of the telescope and the optical axes of the autocollimators are on the same straight line; an adjustable reflector is fixed beside the eyepiece of the tested telescope; the angle of the reflector is adjusted, so that the reflector can be perpendicular to the optical axes of the autocollimators; the adjustable device is fixed so that the device can no longer move; the tested telescope is horizontally turned around the optical axis by 180 degrees; and an angle by which the optical axes deviate from the adjustable reflector 7 is detected, and the angle is the change quantity of the tested telescope 5 under a direct telescope state and areverse telescope state. According to the method of the invention, the change quantity of the optical axis of the calibration telescope under the direct telescope state and the reverse telescope stateis detected through the autocollimators, and therefore, the errors of the optical axis of the calibration telescope under the direct telescope state and the reverse telescope state can be effectivelyreduced; and the optical axis stability of the telescope can be improved.
Description
technical field [0001] The invention belongs to the field of optical technology, and relates to a method for detecting the stability of a telescope optical axis. Background technique [0002] The calibration telescope is mainly used to calibrate the axis error of the radio measurement and control antenna, which plays an important role in the whole system, and its performance affects the measurement accuracy of the measurement and control equipment. [0003] When calibrating the axis system error, calibrate the telescope mirror (pitch angle E<90°) to measure a certain target, and record the measured values of azimuth and pitch angle as A+ and E+ respectively; then, the azimuth rotates 180°, and the pitch rotates 180° -2E+, then use the calibration telescope to measure the same target, and record the measured values of the azimuth and elevation angles as A- and E- respectively, which are called inverted mirrors. Therefore, the error of the optical axis of the calibrati...
