We build new holographic microscopes and develop software to analyze the holograms. 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.

Digital holographic microscopy (DHM) is a novelsurface topography technique that has recently become commercially available. It is a quantitative phase microscopy technique capable of being configured for reflection or transmission microscopy, and it has been used for a variety of applications [1],

Bauwens, “Digital holographic microscopy techniques for multi-focus quantitative phase imaging of living cells,” Biomedical Optical Phase Microscopy and Nanoscopy, 97 –129 Academic Press, Waltham, Massachusetts (2012). 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.

The principal methods for measuring and visualizing phase shifts include ptychography and various types of holographic microscopy methods such as digital holographic microscopy, holographic interference microscopy and digital in-line holographic microscopy.

Currently, deep learning technologies are developing rapidly and have already been The book presents a clear and comprehensive review of the current status of the holographic microscopy with discussion of the positive and negative features of classical and holographic methods for solving the problem of three-dimesional (3D) imaging of phase microscopic objects. 2008-07-01 · Autofocusing in digital holographic phase contrast microscopy on pure phase objects for live cell imaging.

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. Digital holographic microscopy with dual-wavelength phase unwrapping Daniel Parshall and Myung K. Kim We apply the techniques of digital holography to obtain microscopic three-dimensional images of biolog- However, phase information cannot be extracted from these photothermal images, as they are not quantitative. Moreover, the problem of halos inherent in conventional phase contrast microscopy needs to be tackled. Hence, a digital holographic photothermal microscopy technique is proposed as a solution to obtain quantitative phase images. P. Marquet, C. Depeursinge and P. J.

Here we introduce the Multi-focus quantitative phase imaging was performed in transmission with an inverted modular digital holographic microscopy (DHM) setup (fig. 1, light source: frequency doubled Nd:YAG laser, λ = 532 nm) based on a principle described in detail previously [1,4,7] which allows live cell imaging in a temperature stabilized environment. 2015-03-24 · Multimodal holographic microscope, phase image. 10 × magnification 3 h after 2 μM plumbagin treatment. Red-outlined cells show size increase and oncotic phenotype, green-outlined cells show surface area decrease and apoptotic phenotype, blue-outlined cells show no changes during 2 h monitoring.

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.

Phase Holographic Imaging provides an innovative tool that lets you continuously image and monitor your cells directly inside your incubator. Our HoloMonitor ® M4 is a small microscope designed to operate 24/7, inside your normal incubator. Without any labels or stains, it uses digital holography to record your cells in real-time. Other closely related microscopy methods to digital holographic microscopy are interferometric microscopy, optical coherence tomography and diffraction phase microscopy. Common to all methods is the use of a reference wave front to obtain amplitude (intensity) and phase information. 2010-09-01 · 2.
