Common-path incoherent digital holography

Incoherent digital holography plays an important role to expand the application fields of digital holography to bioimaging. There are two configurations to implement the incoherent digital holography. One is the Michelson-type interferometer and the other is to use the common-path configuration using a diffractive optical element. In this invited paper, we briefly present the two configurations of incoherent digital holography and then the experimental results and numerical analysis of common-path incoherent digital holography using the diffractive optical element are described.
