Abstract

A self-adaptive optical system based on voltage decoupling controlled multiple wave-front correctors. The self-adaptive optical system based on the voltage decoupling controlled multiple wave-front correctors comprises a plurality of wave-front correctors, a spectroscope, a wave-front sensor and a wave-front processing machine; the plurality of wave-front correctors are distributed in an optical path in a series connection mode; the wave-front sensor and the wave-front corrector with the highest accuracy satisfy a conjugated relation; the wave-front corrector with the highest accuracy directly performs high-accuracy correction on wave aberrations through a slope method, other wave-front correctors perform voltage decoupling separation on low order wave-front aberrations according to a correction voltage decoupling algorithm of the wave-front corrector which is provided with the highest accuracy, perform type mold correction on specific aberration and directly perform correction on all aberrations through the slope method, finally the correction aberrations of every wave-front corrector are overlayed to achieve high accuracy correction of the overall aberrations. The self-adaptive optical system based on the voltage decoupling controlled multiple wave-front correctors is mainly applied to a light beam purification self-adaptive optical system and the optical fields which have severe aberration change and need a plurality of self-adaptive system combined correction such as correction of atmosphere turbulence and thermal blooming.

technical field [0001] The invention relates to an adaptive optics system, in particular to an adaptive optics system based on a single wavefront sensor controlled by voltage decoupling and controlling a multi-wavefront corrector. Background technique [0002] The adaptive optics system is a system that detects and corrects random optical wavefront aberrations in real time. ) and wave front controllers and other components. The wavefront sensor detects the aberration wavefront information in real time, and the wavefront controller converts the signal detected by the wavefront sensor into the voltage control signal of each driver of the wavefront corrector through the control algorithm, and the voltage control signal drives the wavefront corrector Change the shape of the mirror surface, so as to realize real-time correction of wavefront error.
