Abstract

Optical scanning holography (OSH) is one of the single-pixel imaging (SPI) techniques [1]. The difference between OSH and other SPI techniques is the use of a Fresnel zone plate (FZP) for the illumination patterns. OSH has been applied to various applications because OSH can acquire three-dimensional (3D) spatial information. However, an optical setup for OSH is bulky and complicated due to the requirements of a phase shifter, two-dimensional scanner, and an interferometer to generate the FZP. To overcome the problems, we have proposed motionless OSH (MOSH) [2], which was realized by introducing a liquid crystal type spatial light modulator (SLM), and a strategy of common-path polarization interferometer. In this presentation, we will introduce the recent progress of MOSH.
