摘　　要：围绕光学成像中点扩散函数(Point spread function,PSF)在计算成像中的新内涵与应用,介绍了传统光学成像中PSF的概念以及PSF在光学系统设计中关键作用,并简要说明了几种利用PSF恢复图像算法以及图像评价指标。在此基础上以计算成像框架下信息传递的视角重新审视了PSF的内涵,从狭义、广义光学系统两个方面对计算成像领域中的相关研究进行了归纳总结,最后展望了PSF工程技术的应用前景及发展趋势。This paper focuses on the new connotation and application of point spread function(PSF)of optical imaging in computational imaging.Firstly,the conception of PSF in traditional optical imaging and the key role of PSF in optical system design are introduced,and several algorithms for imaging restoration using PSF and imaging evaluation indices are briefly explained.On this basis,the connotation of PSF is re-examined from the perspective of information transfer under the framework of computational imaging,and relevant researches in the field of computational imaging are summarized from the two aspects of narrow and generalized optical systems.Finally,the application prospect and development trend of PSF engineering technology are prospected.
