Integrated oscillating mirror adjustment method

Abstract

The invention relates to an integrated oscillating mirror adjustment method. The rotating axis of a rotating shaft is led out through a small reflector on the rotating shaft and transferred to the normal of the -X plane of an oscillating mirror cube mirror, the high-precision form and position tolerance of six faces of the oscillating mirror cube mirror is utilized, and the position assembly of avisible light reflector and an infrared reflector can be simplified to achieve pointing consistency of the normals of the two reflectors and the normals of the +Z face and the -Y face of an oscillating mirror accurate measurement mirror. According to the integrated oscillating mirror adjustment method, the assembly difficulty of the oscillating mirror and the assembly difficulty of the oscillatingmirror in a system can be greatly reduced.

Description

technical field [0001] The invention relates to a method for installing a swing mirror, in particular to an integrated method for installing and adjusting a swing mirror. Background technique [0002] With the continuous development of space payload technology, single-band single payload can only obtain limited information of the target, and the detection range in the direction of orbit is limited, so it cannot meet the current development needs of spaceborne detection. So now there are two same payloads or two payloads with different bands to detect at the same time. This mode requires the payload to be placed at a certain angle on the satellite, or a V-shaped one that can be swung along the orbital direction is added before the payload. mirrors, such as figure 1 As shown, and this technical means can not only realize the loads of two bands to detect the same ground object at the same time, but also realize the expansion of the width. The whole system includes infrared in...

Problems solved by technology

Specifically, the two reflectors (infrared reflector and visible light reflector) need to ensure a 90° included angle, and the two reflectors and the rotating shaft need to ensure a 90° included angle. The rotating shaft carries the two reflectors and the optical axis of the main optical system ( Optical axis 1 and optical axis 2) ensure pointing consistency, and these angles will affect the coincidence degree of the target in the Y and Z directions of the target surface of the two load detectors and the inclination angle between the satellite flight direction and the detector Z direction (satellite drift angle ), which ultimately affects image restoration
