Före börsöppning: Thor Industries Stämmor 10:00 Nexar (extra), 10:00 Qliro Group (extra),  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. Holographic microscopy is the most common form of quanti­tative phase imaging.

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.

This allows the results to be directly correlated with absolute biophysical parameters. 2011-11-03 2017-02-08 Recently digital holographic microscopy (DHM), a variant of quantitative phase microscopy 14, was identified as useful tool for the evaluation of epithelial wound healing in vitro and in vivo 15. DHM allows assessment of tissue density by measuring optical path length delay (OPD), which prospects novel cancer diagnosis 16-18 and quantification of inflammation related tissue alterations 19 . Conventional interferometric microscopy techniques such as digital holographic microscopy and quantitative phase microscopy are often classified as 3D imaging techniques because a recorded complex field image can be numerically propagated to a different depth.

Holographic microscopy.

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. 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.

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.
