Intelligent control method of adaptive optics system based on energy distribution decision

Abstract

The invention discloses an adaptive optics system intelligent control method based on energy distribution judgment. The basic idea of this method comprises the steps of first, experimentally measuring a weight matrix B corresponding to a Hartmann array lens; then, carrying out energy binarization of optical spots formed in sub-apertures of the Hartmann array lens according to observed results to obtain a 0 / 1 matrix A; and making a judgment of full aperture energy distribution of the Hartmann array lens according to C=Sum (A.B)>T, and transmitting a command to close a loop or not to an adaptive optics system according to the judgment result. The invention provides the intelligent control method for controlling the adaptive optics system to automatically open and close the loop, and for a conventional adaptive optics system, the introduction of the method allows the manpower input of the system to be reduced and has great help in automatic and intelligent operation of the adaptive optics system.

Description

technical field [0001] The invention relates to the technical field of adaptive optics intelligent control, in particular to an intelligent control method of an adaptive optics system based on energy distribution judgment, which is mainly used to control the adaptive optics system to perform automatic open-loop and closed loop. Background technique [0002] The adaptive optics system enables the optical system to automatically adapt to changes in external conditions and maintain a good working condition through real-time detection, control and correction of wavefront distortion. The adaptive optics system consists of three parts: a wavefront sensor, a wavefront controller and a wavefront corrector. At present, most adaptive optics systems usually use a Shack-Hartmann wavefront sensor for wavefront detection. The Hartmann wavefront sensor detects the wavefront distortion in real time. After the signal is processed by the wavefront controller, a control signal is generated an...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to overcome the deficiency that the open-loop and closed-loop of the adaptive optics system requires manual intervention, and propose an intelligent control method for the adaptive optics system based on energy distribution judgment. The weight matrix of the weight matrix, and then detect the light spots formed in each sub-aperture of the Hartmann array lens to obtain the energy binarization matrix, and compare the sum of the dot product results of the energy binarization matrix and the weight matrix with the threshold to decide whether to send closed-loop commands to the adaptive optics system
