A constrained method for lensless coherent imaging of thin samples

Abstract

Lensless inline holography can produce high-resolution images over a large field of view (FoV). In a previous work [Appl. Opt. 60, B38 (2021) [CrossRef]  ], we showed that (i) the actual FoV can be extrapolated outside of the camera FoV and (ii) the effective resolution of the setup can be several times higher than the resolution of the camera. In this paper, we present a reconstruction method to recover high resolution with an extrapolated FoV image of the phase and the amplitude of a sample from aliased intensity measurements taken at a lower resolution.
