Depth-filtered digital holography
Optics Express, 2012 We introduce depth-filtered digital holography (DFDH) as a method for quantitative tomographic phase imaging of buried layers in multilayer samples. The procedure is based on the acquisition of multiple holograms for different wavelengths. Analyzing the intensity over wavelength pixel wise and using an inverse Fourier transform leads to a depth-profile

Spatial 3D imaging by synthetic and digitized holography [PDF]
, 2011 A novel method named digitized holography is proposed for 3D display systems. This is the technique replacing the whole process of classical holography with digital processing of optical wave-fields.

Multiwavelength-multiplexed phase-shifting incoherent color digital holography.
Optics Express, 2020 We propose multiwavelength-multiplexed phase-shifting incoherent color digital holography. In this technique, a monochrome image sensor records wavelength-multiplexed, phase-shifted, and incoherent holograms, and a phase-shifting interferometry technique
