The Q-PHASE is purposely designed to observe living cells in vitro . 2020-11-01 · A totally automatic and robust phase aberration compensation method is proposed for digital holographic microscopy. The correction needs no manual operation or prior knowledge of the recording setup. As the phase aberrations are modeled with orthogonal polynomials, not only phase curvature but also high order aberrations could be corrected with a single hologram. 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. 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.

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. The hologram results from the interference of the object beam with a reference wave that can be kept separate from
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. Holographic microscopy is a method of quantitative phase imaging. Providing intrinsic high contrast, phase images allow an easy segmentation of cells from the image background and monitor morphological and position changes over the time [ 14 ]. Quantitative phase imaging and digital holographic microscopy have shown great promise for visualizing the motion, structure, and physiology of microorganisms and mammalian cells in three dimensions. However, these imaging techniques currently lack molecular contrast agents analogous to the fluorescent dyes and proteins that have revolutionized fluorescence microscopy. Here we introduce the
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.

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.
Direct access to the phase as well as amplitude profiles makes quantitative phase microscopy by digital holography (DH-QPM) particularly powerful and versatile. Digital holographic microscopy with phase-shift-free structured illumination Juanjuan Zheng,1 Peng Gao,1,2 Baoli Yao,1,* Tong Ye,3 Ming Lei,1 Junwei Min,1 Dan Dan,1 Yanlong Yang,1 and Shaohui Yan1 Holographic microscopy creates (quantitative) phase images by letting a sample beam and a reference beam interfere to create an interference pattern or hologram. The hologram is recorded by an image sensor and computer processed to produce the phase image. In this work, we propose an innovative method for digital holographic microscopy named as photorefractive phaseconjugation digital holographic microscopy (PPCDHM) technique based on the phase conjugation dynamic holographic process in photorefractive BaTiO3 crystal and the retrieval of phase and amplitude of the object wave were performed by a reflection-type digital holographic method. 2011-12-02 · High-Speed Three-Dimensional Microscope for Dynamically Moving Biological Objects Based on Parallel Phase-Shifting Digital Holographic Microscopy Abstract: We succeeded in 3-D motion-picture imaging for dynamic motion of biological objects swimming at different depths by parallel phase-shifting digital holographic microscopy (PPSDHM).
