What is the depth of field reachable in practice with generic binary phase masks and digital deconvolution?

Abstract : We investigate the practical behavior of a co-optimized hybrid system involving a generic binary phase mask and digital deconvolution. We perform experiments with a case-study optical system with observed scene lighting by LED of different colors. By imaging a real scene and a depth of field (DoF) target, we show that the DoF reachable in practice matches with good accuracy the one predicted by simulation in case of monochromatic illumination. We also characterize the drop in performance when using this type of system with actual illumination wavelength departing from the nominal one.
