Abstract

Optical scanning holography (OSH) has been researched as one of single pixel holography. Although incoherent holograms can be obtained with a bucket detector, OSH requires sequentially scanning an illumination pattern on an object with a moving stage and a phase shifter. This fact imposes disadvantages of unstable and bulky setup on OSH. To solve the problem, we have proposed the OSH technique without mechanical scanning by using a polarization property of a spatial light modulator. The proposed technique makes its setup inline and simple due to absence of moving parts. In this presentation, a basic principle of the proposed technique and its improvement based on parallel phase shifting and compressive sensing are introduced.
