An Apodization Mask Based on Circle Grating Function with Different Space in Confocal Microscope

针对带有光瞳掩模的超分辨系统 ,提出了一种基于极坐标的性能评价标准。同时根据衍射光学相关理论 ,提出了变距圆光栅函数掩模花样。模拟计算结果表明 ,在共焦系统中利用该掩模可以改变系统的点振幅响应 ,从而提高分辨率 ,并增强图像的反衬度。

The performance evaluation criterion based on polar coordinates is presented for the system with superresolving pupil mask. Then a mask based on circle grating function with different spacings and a math model are presented. The computation simulation results show that in confocal optic system this mask can change the point amplitude response. It can improve the resolution, while increase the image contrast.
