Compressive holography with phase-structured illumination

Abstract

We describe several approaches to perform digital holography with single-pixel detection by using phase-structured illumination and compressive sensing. Single-pixel imaging works by sampling the scene with micro-structured amplitude patterns implemented onto a spatial light modulator and recording light intensity fluctuation with a simple photodiode. Recently, we have demonstrated the capability of this technique to record digital holograms and to transmit images through scattering media. In this contribution we describe new optical interferometer architectures to record complex amplitude distributions using a simple photodiode by sampling the scene with micro-structured phase patterns. Preliminary experimental results are shown.
