Abstract

We propose a compressive self‐interference incoherent digital holography (SIDH) with a geometric phase metalens for section‐wise holographic object reconstruction. We specify the details of the SIDH with a geometric phase metalens design that covers the visible wavelength band, ana-lyze a spatial distortion problem in the SIDH and address a process of a compressive holographic section‐wise reconstruction with analytic spatial calibration. The metalens allows us to realize a compressive SIDH system in the visible wavelength band using an image sensor with relatively low bandwidth. The operation of the proposed compressive SIDH is verified through numerical simu-lations.
