Imaging in digital holographic microscopy
Optics Express, 2007 We present a theoretical formalism for three dimensional (3D) imaging properties of digital holographic microscopy (DHM). Through frequency analysis and visualization of its 3D optical transfer function, an assessment of the imaging behavior of DHM is given. The results are compared with those from other types of interference microscopy.

Parallel phase-shifting digital holographic microscopy [PDF]
Biomedical Optics Express, 2010 We propose parallel phase-shifting digital holographic microscopy (PPSDHM) which has the ability of three-dimensional (3-D) motion measurement using space-division multiplexing technique. By the PPSDHM, instantaneous information of both the 3-D structure and the phase distributions of specimens can be simultaneously acquired with a single-shot exposure.

Digital Holographic Microscopy [PDF]
Imaging and Applied Optics 2016, 2011 Digital holographic microscopy (DHM) is an interferometric technique that measures 3D topography from a single image, acquired in a few microseconds. With these features, DHM performs real-time measurements, up to twenty frames per second in live mode, and is only limited by the camera acquisition rate in post processing mode.
