An Introduction of Application of Computational Imaging in Photoelectric Detection(Invited)

为了解决以物像共轭为核心的传统成像技术信息获取方式受限、解译能力不足等造成的成像探测距离近、大视场与高分辨率实时成像难以及重建图像质量差等问题,以信息驱动为核心的计算成像技术应运而生,且在光电探测中表现出巨大潜力。本文从传统成像的瓶颈难点出发,阐述了计算成像的概念与内涵,着重分析了计算成像链路中计算介质、计算光学系统及计算处理在成像、探测中的作用与优缺点,并对计算成像在光电探测中的未来发展做了展望。

In order to solve the problems of short detection distance,difficulty in acquiring large field of view and high-resolution real-time imaging,and poor quality of reconstructed images,which are caused by the limited information acquisition methods and insufficient interpretation capabilities of traditional imaging technology with object-image conjugation as the core,computational imaging technology with core information-driven came into being,and it has shown great potential in photoelectric detection.In this paper,the concept and connotation of computational imaging are illustrated from the beginning of the bottleneck problem in traditional imaging.And then the computational media,computational optical systems and computing processing in the imaging link are deeply analyzed.Meanwhile,the role,advantages and disadvantages of computational imaging in imaging and detection are summarized,and the future development in photoelectric detection field is prospected.
