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.
我们针对包含多层衍射光学元件（MLDOE）的混合光学系统提出了一种压缩图像质量评估方法。我们考虑了入射角和波段的影响，以提高MLDOE的衍射效率。通过这种MLDOE设计，可以确保对混合光学系统进行准确的图像质量评估。结果表明，这种设计能够实现衍射效率提高的MLDOE，并进一步确保混合监控镜头的调制传递函数具有准确的图像质量以及更好的光学系统结构。这些结果对于混合成像光学系统的优化设计具有重要意义。
