Correcting dynamic residual aberrations of conformal optical systems using AO technology被引量：2
《Chinese Physics B》2009年第7期2769-2773,共5页李岩 李林 黄一帆 杜保林 
Project supported by the National High Technology Research and Development Program of China (Grant No 2006AA012339)
This paper analyses the dynamic residual aberrations of a conformal optical system and introduces adaptive optics （AO） correction technology to this system. The image sharpening AO system is chosen as the correction...

Study on the design and Zernike aberrations of a segmented mirror telescope
《Chinese Physics B》2009年第7期2774-2778,共5页姜震宇 李林 黄一帆 
Project supported by the National High Technology Research and Development Program of China (Grant No 2006AA01Z339)
The segmented mirror telescope is widely used.The aberrations of segmented mirror systems are different from single mirror systems.This paper uses the Fourier optics theory to analyse the Zernike aberrations of segmen...

Restoration of solar and star images with phase diversity-based blind deconvolution被引量：1
《Chinese Optics Letters》2007年第4期201-203,共3页李强 廖胜 魏宏刚 沈忙作 
This work was supported by the National"863"Program of China under Grant No.8632774.
The images recorded by a ground-based telescope are often degraded by atmospheric turbulence and the aberration of the optical system. Phase diversity-based blind deconvolution is an effective post-processing method t...

Evaluations on aero-optic effects of subsonic airborne electro-optical system被引量：6
《Chinese Optics Letters》2006年第8期435-438,共4页殷柯欣 姜会林 
This work was supported by the National "863" Program of China.
A simple method based on CFD code and Matlab from CFD code due to the changes of such factors is introduced as an input to Matlab. The overall for aero-optic effects is presented. Density fluctuation as altitude, spee...
