WebSep 16, 2024 · For object points that are not on the optical axis, the PSF is translated such that it is centred on the ideal Gaussian image point. Usually we assume that we know the field transmitted or reflected by an object in the socalled object plane, which is the plane immediately behind the object (on the side of the lens). WebThe DOE structure partially resembles that of a grating, which creates multiple peaks in the point spread function (PSF, right). Intuitively, this PSF creates three shifted and scaled copies of the input image. ... Deep Optics for Depth Estimation and Object Detection. ICCV 2024 ; Peng et al. 2024.
