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。 Based on the characteristics of birefringent wave plate, a continuously adjustable super-resolution pupil filter with dual adjustment mode is proposed. This filter achieves super resolution by two adjustment modes and is continuously adjustable within a certain range. In lateral rotation mode, the filter is a complex amplitude pupil filter and the vertical phase tilt mode is a pure phase super resolution filter. Through the analysis of super-resolution parameters, the best design parameters can be obtained, which can achieve a large field of view, a large super-resolution range, high adjustment accuracy. This filter provides more convenience for practical use.
