Optical Scanning Holography – A Tutorial and an Overview of Recent Advances

Optical scanning holography (OSH) is a single-pixel digital holographic recording technique. Applications of the technique include optical scanning cryptography, 3-D microscopy, 3-D pattern recognition, 3-D holographic TV, and 3-D optical remote sensing. In this tutorial, I will first provide the basic principle of OSH. I will then give an overview of some of the recent advances that have been made on OSH.
