Problems solved by technology

[0005] The technical problem solved by the present invention is: to overcome the problem of insufficient correction caused by the contradiction between the stroke of the wavefront corrector and the spatial frequency in the conventional adaptive optics system, and to provide a method that realizes large low-order aberrations and relatively small The high-order aberrations of the two wavefront correctors are respectively corrected by two wavefront correctors with larger strokes and higher spatial frequencies. Adaptive optics system with dual wavefront correctors

Embodiment Construction

[0018] Such as figure 1 As shown, the present invention comprises a tilting reflector 1, two wavefront correctors 2 and 3, a beam splitter 4, a wavefront detector 5, a wavefront processor 6, a computer 7, and a laser beam 8 passes through the tilting reflector 1, The two wavefront correctors 2 and 3 reach the beam splitter 4, part of the energy is reflected by the beam splitter 4, and the other part of the energy enters the wavefront detector 5 through the beam splitter 4, and the optical wavefront slope information G of the laser beam 8 is captured by the wavefront It is detected by the front detector 5, and then the control voltages of the two wavefront correctors are calculated respectively through the slope vector G, so as to realize the separation of large low-order aberrations and high-order aberrations, and the control of the two wavefront correctors Separation, and then realize the stable closed loop of the whole system.

[0019] In the present invention, the low-orde...

Abstract

This invention relates to double wave pre-corrector self-adapting optical system, which comprises incline reflection lens, two before wave correctors, before wave sensor, splitter lens, before wave processor, two before wave correctors, which separately realize the low and high picture difference correction as needed. The before wave corrector needs large journey to correct the low picture difference and the before wave corrector has larger space frequency.

Description

technical field [0001] The invention relates to an adaptive optics system, in particular, it can overcome the gap between the stroke of the wavefront corrector and the resolution when the conventional adaptive optics system contains large low-order aberrations and high-order aberrations at the same time. Contradiction, a dual-wavefront corrector adaptive optics system that improves the correction capability of the system. Background technique [0002] The adaptive optics system is a system that detects and corrects random optical wavefront aberrations in real time. Front controller and other components. The wavefront detector detects the aberration wavefront information in real time, and the wavefront controller converts the signal detected by the wavefront detector into the control signal of the wavefront corrector through the control algorithm, and drives the wavefront corrector to change the shape of the wavefront , so as to realize the real-time correction of the wavef...
