Google Scholar 2020-09-24 · A low-pass filtering compensation (LPFC) method is proposed to compensate for phase aberrations in point diffraction-based common-path digital holographic microscopy. We propose parallel phase-shifting color digital holographic microscopy (PPSCDHM) which is capable of both color imaging and three-dimensional (3-D) motion measurement by using space-division multiplexing technique. By the PPSCDHM, instantaneous information of not only the 3-D structure of specimens but also the spectral image can be simultaneously acquired with a single-shot exposure. The Thus, phase microscopy techniques provide neither a 3-D image of the cell nor a 3-D map of the refractive index distribution. One strategy for 3-D determination of refractive index is based on measurement of projections of refractive index in multiple directions, in analogy to computed x-ray tomography, in which the projection of absorption is measured.

High-resolution imaging of densely connected samples such as pathology slides using digital in-line holographic microscopy requires the acquisition of several holograms, e.g., at >6-8 different sample-to-sensor distances, to achieve robust phase recovery and coherent imaging of specimen.

February 2006; The method of three-wavelength phase imaging is proposed to extend the axial range and reduce the effect Digital holographic microscopy (DHM) is a potent tool to perform three-dimensional imaging and tracking. We present a review of the state-of-the-art of DHM for three-dimensional profiling and tracking with emphasis on DHM techniques, reconstruction criteria for three-dimensional profiling and tracking, and their applications in various branches of science, including biomedical microscopy 2016-05-18 Digital holographic microscopy is an emerging modality that offers capability of quantitative phase imaging (QPI) of transparent unstained cells in their most natural state. While phasesensitive imaging methodologies such as dark-field, phase contrast and differential interference contrast are known for several decades, they cannot provide quantitative phase information.
