A novel speckle reduction technique for digital holography is proposed. Multiple off-axis holograms are recorded using a circularly polarized illumination beam and a rotating linearly polarized reference beam. The speckle noise in the reconstructed images is suppressed by averaging these fields. We demonstrate the effectiveness of this technique experimentally and conduct additional statistical evaluation.

卡塞格林光学系统的结构严重限制了视场,通常需添加辅助光学元件来扩大视场,但将导致系统结构复杂,不利于光学系统的小型化、轻量化。提出一种计算成像设计方法,首先优化系统结构参数,控制像差;然后构建系统的点扩展函数模型;最后采用反卷积算法处理图像。所提方法仅利用主、次镜结构就扩大了卡塞格林系统的视场。对F数为5.5,焦距为470 mm的卡塞格林系统进行仿真实验,实验结果表明,在1.5°视场范围内,处理后
