Holographic microscopy is the most common form of quantitative phase imaging. The HoloMonitor ® live cell imaging microscope employs digital holographic microscopy to allow non-invasive visualization and quantification of living cells without compromising cell integrity.

It is effective, fully automatic, and does not require any … Quantitative phase-digital holographic microscopy (QP-DHM) represents an important and efficient quantitative phase method to explore cell structure and dynamics. In a second part, the most relevant QPM applications in the field of cell biology are summarized. 2012-11-01 Digital holographic microscopy is a quantitative phase measurement technique that can provide nanometer resolution of the thickness or surface profile of an object. We analyze the influence of additive noise in the hologram plane on the accuracy of We use a fast imaging method called holographic microscopy to watch self-assembling systems. In a holographic microscope, the sample is illuminated by laser light, and the resulting image (or hologram) can be used to determine the 3D structure, position, and orientation of a microscopic sample. We build new holographic microscopes and develop software to analyze the holograms.

Digital holographic microscopy (DHM) 2,3 is an interferometry -based variant of QPI that typically uses a laser as a coherent light source and provides QPI by detecting specimen-induced optical path length changes against the surrounding environment.

The proposed method decomposes the phase map into a set of values of uncorrelated variables called principal components, and then extracts the aberration terms from the first principal component obtained. DH obtains both amplitude and phase distributions of an object wave simultaneously and quantitatively.

The application of DH to microscopy is called digital holographic microscopy (DHM). DHM is also called 3D microscopy [14, 18] and quantitative phase microscopy [14, 17, 19]. The amount of phase shift is determined by the optical thickness, which depends on both the index of refraction inside the object and the object thickness. The phase shift can be measured with a resolution down to nanometers [5]. The principles for the digital holographic microscope have recently been reviewed by Kemper and von Bally [6]. 2019-07-05 · Dual-wavelength common-path digital holographic microscopy for quantitative phase imaging based on lateral shearing interferometry.

The phase shift image is unique for digital holographic microscopy and gives quantifiable information about optical distance. In reflection DHM, the phase shift image forms a topography image of the object.

In particular, the angular spectrum method of calculating holographic optical field is seen to have significant advantages including tight control of spurious noise components. Holographic phase images are obtained with 0.5 μm diffraction-limited 2. 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. 2.2 Quantitative Phase Digital Holographic Microscopy A digital holographic microscope37 comprises both an optical setup devoted to hologram formation and software specially developed to numerically process the digitized hologram.
