Cube mirror rapid adjustment apparatus of space photoelectric sensor and adjustment method thereof

Abstract

The invention discloses a cube mirror rapid adjustment apparatus of a space photoelectric sensor and an adjustment method thereof. The cube mirror rapid adjustment apparatus comprises a cube mirror, an adjusting seat, a casing, a screw and a tool, the tool and the casing are fixedly connected, an adjusting seat is used for adjusting the cube mirror is arranged at the casing, a screw hole used forarranging the screw is arranged at the casing, the screw is arranged by passing through the screw hole, and is cooperated with the adjusting seat to adjust the rotation angle of the cube mirror. Through the cooperation of the adjusting seat, the casing, and a tapered fastening screw, a coordinate system of the cube mirror of the space sensor and the calibration speed of a machinery coordinate system are increased, the defects of the traditional coordinate system of the cube mirror of the space sensor and the calibration speed of the machinery coordinate system can be made up, by using a photoelectric autocollimator and a planar mirror for measurement, synchronous measurement and adjustment can be realized, and the problem of poor calibration precision of the traditional coordinate system of the cube mirror of the space sensor and the calibration speed of the machinery coordinate system can be overcome.

Description

technical field [0001] The invention relates to a cubic mirror quick assembly and adjustment device of a space photoelectric sensor and an assembly method thereof, and belongs to the technical field of optical-mechanical adjustment and measurement of a space photoelectric sensor. Background technique [0002] Space photoelectric sensor products, such as star sensors, sun sensors, etc., are mostly used for attitude measurement of spacecraft. The product generally defines three coordinate systems, which are the measurement coordinate system, the mechanical coordinate system and the cubic mirror coordinate system. In practical applications, in order to transform the attitude information output by the sensor into the coordinate system of the spacecraft, it is first necessary to establish the conversion relationship between the measurement coordinate system and the cubic mirror coordinate system; Measurement, that is, to establish the transformation relationship between the spac...
