利用Offner光学系统进行图像恢复和光学检测
Image restoration and optical test by using Offner optical system
摘要
Abstract
Based on phase diversity technology, this paper designs an Offner optical system for image restora- tion and optical test of wavefront errors. The Offner optical system uses an on-axis parabolic mirror as Offner mirror, and a high speed CCD camera and a Shack-Hartmann wavefront sensor as the receivers to eliminate the chromatic aberration brought by the polychrome light source of the refractive system during image restoration. The system has a simple configuration with the wavefront error(RMS) less than A/50 (A = 632.8 nm). By u- sing the system to perform image restoration experiment for a resolution plate and a fiber source, the resolution of restorated system using tween phase image is improved by 19%. In addition, wavefront error test are performed with the Offner optical the phase diversity algorithm, and the result demonstrates that the wavefront sensor difference be- diversity and Shack-Hartmann is 5% , which proves that it is able to perform optical wavefront test with this Offner optical system.关键词
