【摘要】 在给定斯特列耳比S(超分辨模型和爱里模型最大亮度比)和分辨率参数G(用滤波器时和不用滤波器时系统横向光强第一极小值之比)的条件下设计三区位相型光瞳滤波器,用来提高系统横向分辨率.考虑到强烈的旁瓣效应,把位相型滤波器应用于共焦扫描显微系统,提高了分辨率.更多还原

【Abstract】 For improving the transverse resolution, 3-zone phase-only filters are designed at the special Strehl ratio S, which is the ratio of the maximum intensity of the central core of the superresolving pattern to the Airy pattern, and the special resolution parameter G, which is the ratio between the first minimum of the transverse intensity of the superresolving pattern and the unobstructed pattern. To suppress the strong sidelobe intensity, these phase-only filters are used in the confocal scanning microscopy system with good resolving effects achieved.更多还原
