Comparative study on the power scaling performance of three different coherent polarization beam combination system structures
《Chinese Physics B》2012年第9期286-294,共9页马鹏飞 周朴 马阎星 粟荣涛 刘泽金 
Coherent polarization beam combination (CPBC) is a new kind of coherent beam combination configuration with high combining efficiency and excellent beam quality. In order to extend the CPBC system to a large scale, ...

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...

Aberration-free two-thin-lens systems based on negative-index materials
《Chinese Physics B》2008年第3期954-959,共6页林志立 丁婕深 张朴 
Project partially supported by the National Basic Research Program of China(Grant No2004CB719802);an additional support from the Science and Technology Department of Zhejiang Province,China
Since the complete correction of all five monochromatic Seidel aberrations for a singlet lens with random shape or a two-thin-lens system is unprocurable merely by using the conventional positive-index materials both ...
