Image stabilization control system and control method of fast reflectors

Abstract

The invention discloses an image stabilization control system and an image stabilization control method of fast reflectors. The image stabilization control system comprises an imaging assembly, a photoelectric detector, a position information processor, a controller and a driving device, wherein the imaging assembly receives an optical signal and generates a to-be-detected image; the photoelectricdetector receives the to-be-detected image and converts the to-be-detected image into an electric signal; the position information processor receives the electric signal and calculates image offset of the electric signal; the controller receives the image offset, calculates target angle positions required by the fast reflectors according to the image offset, obtains a current position of each fast reflector, and calculates to obtain the driving amount required by the faster reflectors according to the current positions and the target angle positions of the fast reflectors; and the driving device drives the current fast reflector to perform swing angle motion according to the driving amount required by the current fast reflector. Through using a jitter detection module composed of the independent imaging assembly, the photoelectric detector, the position information processor and the controller, when a plurality of imaging telescopes exist at the same time, the same jitter detection module can be used together, and therefore the implementation difficulty and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an image stabilization control system and control method for a fast mirror. Background technique [0002] Due to the influence of the stability of the satellite attitude control and the vibration generated by the operation of other equipment on the star, the pointing of the space solar telescope toward the sun will shake, which will cause the shaking of the image on the image sensor, which will have a great impact on the final imaging effect. The effect, which reduces the image resolution, is more serious for space solar telescopes that require long exposures. [0003] At present, the optical image stabilization method mainly uses the imaging image sensor as the shake detection sensor, and forms a closed-loop control system with the fast mirror to achieve image stabilization. Since the image sensor used for imaging is used to detect shaking, it may affect normal imaging,...
