Abstract

The invention relates to a calibration system and calibration method for the double-collimation zero-position angle of an optical transmission device. The system has a simple structure and can efficiently calibrate the double-collimation zero-position angle of the optical transmission device under high and low temperature conditions. The system comprises an electronically controlled turntable, a double-sided mirror and a two-dimensional adjustment table arranged in a constant temperature test box and a first Porro prism device, a first multi-tooth indexing table, a second Porro prism device, asecond multi-tooth indexing table, a self-collimating theodolite, and a plane mirror.

Description

technical field [0001] The invention belongs to the field of optics, and in particular relates to a calibration system and a calibration method for an included angle between double collimation and zero positions of an optical transmission device. Background technique [0002] As an optical instrument, the optical transmission device is widely used in the field of spacecraft launch, and it is an important part of the automatic aiming platform in this field. The optical transmission device has the function of using the principle of self-collimation optics to perform small-angle measurement, which can realize the aiming and transmission of azimuth information, and finally assist in the completion of the position orientation of the spacecraft launch. [0003] The optical transmission device belongs to the multi-optical axis system, which is mainly composed of two collimators, one large and one small. The zero angle between the large and small collimators, that is, the double-co...
