【摘要】 基于双折射波片的特性,提出了一种具有双调节模式的连续可调超分辨光瞳滤波器。该滤波器通过两种调节模式实现超分辨,且在一定范围内连续可调。在横向旋转模式下,该滤波器为复振幅型光瞳滤波器,纵向倾斜模式下为纯相位型超分辨滤波器。通过对超分辨参量的分析,得到最佳设计参量,可以实现大的视场角,大的超分辨范围、高的调节精度。这种滤波器为实际应用提供了更多的方便。更多还原

【Abstract】 A double-mode adjustable superresolving pupil filter based on birefringent filter is proposed.This filter can obtain superresolution in two modes of adjustment and is continuously adjustable.In the transversal rotation mode,the pupil filter acts as complex amplitude filter and as pure phase filter in the longitudinal tilting mode.By analyzing two superresolving parameters,the optimal designing parameters are got,which ensure a large field of view,a large superresolving range and a high setting accuracy.This filter can provide more flexibility in practical applications.更多还原
