We experimentally compare results from three different prototypes — (a) amplitude mask designed for separable PSF (FlatCam [10]), (b) phase mask designed for separable PSF, and (c) proposed phase mask designed for Contour PSF. The camera thicknesses are approximately 2 mm. FlatCam reconstructions are performed using Tikhonov regularization [10], and using deep learning method [49]. Both the phase-mask reconstructions are performed with Eq. 9. The proposed PhlatCam produces cleaner and higher quality images.
