我们提出了一个包含多层衍射光学元件（MLDOE）的混合光学系统的压缩图像质量评估。我们同时考虑了入射角度和波段的影响，提高了MLDOE的衍射效率。采用该设计，可以保证混合光学系统图像质量的准确评估。结果表明，该设计实现了提高衍射效率的MLDOE，进一步保证了调制传递函数的准确图像质量和混合监视镜头的光学系统结构。研究结果对混合成像光学系统的优化设计具有重要意义。(C) 2020美国光学学会
We present a compressive image quality evaluation for a hybrid optical system containing a multilayer diffractive optical element (MLDOE). We take effects from both incident angle and waveband into consideration to improve the diffraction efficiency of the MLDOE. With this MLDOE design, it can ensure accurate image quality evaluation for hybrid optical systems. The results show that this design enables a diffraction-efficiency-improved MLDOE, and further ensures accurate image quality of the modulation transfer function and better optical system structure of the hybrid surveillance lens. The results are of great significance for the optimal design of hybrid imaging optical systems. (C) 2020 Optical Society of America
