• The science of investigating small objects using such an instrument is called microscopy. 3. In digital holographic microscopy, phase aberrations, which are usually caused by the imperfections of components and nontelecentric configuration of the optical system, severely affect the visualization and quantitative measurement for phase-contrast imaging. B. KemperP.

Although not applicable to quantitative phase measurement, single-exposure, on-axis Gabor holographic microscopy has been shown to work reasonably well for 3-D cell identification, with a large gain in simplicity, compactness and expense that is very valuable for point-of-care health solutions.

Parallel phase-shifting digital holographic microscopy (PPSDHM) Figure 1(a) shows a block diagram of the PPSDHM. A perpendicularly polarized light beam is emitted from the laser and is split into two beams by a beam splitter. One beam illuminates the specimen, and then the scattered light from the specimen is collected by a microscope objective. 2021-03-22 · Digital holographic microscopy enables the measurement of the quantitative light field information and the visualization of transparent specimens.

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.
