annular pupil meaning in English

环状光瞳

Finally , the schwarzschild objective of euvl is assembled and aligned on the common - axis illuminated structure with the wfe of 0 . 0202x ( a , = 632 . 8nm ) rms . using an off - axis circular subaperture of the full annular pupil , the wfe of the schwarzschild objective is 0 . 0144a , ( x = 632 . 8nm ) rms
最终对euvl系统中的schwarzschild微缩投影光学系统进行装调，验证了系统装调的收敛性，装调后系统的最终波像差为0 . 0144 rms ( = 632 . 8nm ) 。
For this purpose , by combining techniques of optical superresolution and image superresolution , this thesis proposes a novel lateral superresolution confocal microscopy method based on image restoration and annular pupil filtering . the following two aspects are the main research work i have completed so far . first , designed and realized a shaped annular beam confocal microscopy system ( sabcms ) , in order to improve the lateral resolution of cm
第二,对整形环形光共焦显微系统所成像进行基于最大似然估计法( maximumlikelihoodestimate , mle )的超分辨复原处理,以期进一步改善共焦显微镜的横向分辨力,具体包括: 1 .实现基于pmle ( mlebasedonpoissondistribution )法的图像复原式整形环形光横向超分辨共焦显微成像系统。
