Using holograms created in digital microscopes and interpreted using artificial intelligence (AI), researchers can now follow the lives of microplankton at the individual level for the first time. The method is the result of an interdisciplinary research project at the University of Gothenburg. https://phys.org/news/2022-11-holographic-microscopy-insights-life-microplankton.html Cell & Microbiology Tue, 01 Nov 2022 11:21:03 EDT news586520461 In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate the developed image with a replica of the reference beam to create a virtual image of the original object. Holography was originally proposed by the physicist Dennis Gabor in 1948 to improve the resolution of an electron microscope, demonstrated using light optics. A hologram can be formed by capturing the phase and amplitude distribution of a signal by superimposing it with a known reference. The original concept was followed by holography with electrons, and after the invention of lasers optical holography became a popular technique for 3-D imaging macroscopic objects, information encryption and microscopy imaging. https://phys.org/news/2019-05-holographic-imaging-electromagnetic-fields-electron-light.html General Physics Wed, 15 May 2019 09:30:01 EDT news477037042 A portable holographic field microscope developed by UConn optical engineers could provide medical professionals with a fast and reliable new tool for the identification of diseased cells and other biological specimens. https://phys.org/news/2017-10-portable-holographic-microscope-field-diagnosis.html Optics & Photonics Tue, 31 Oct 2017 09:42:11 EDT news428661722 A new system developed by UCLA researchers could make it easier and less expensive to diagnose chronic diseases, particularly in remote areas without expensive lab equipment. https://phys.org/news/2017-08-hologram-technology-chronic-diseases-remote.html Optics & Photonics Mon, 14 Aug 2017 04:22:22 EDT news421903320 Today in the journal Nature, researchers at MIT's Media Lab report a new approach to generating holograms that could lead to color holographic-video displays that are much cheaper to manufacture than today's experimental, monochromatic displays. The same technique could also increase the resolution of conventional 2-D displays. https://phys.org/news/2013-06-cheap-holographic-video.html Optics & Photonics Wed, 19 Jun 2013 13:00:12 EDT news290865162 Aydogan Ozcan, whose invention of a novel lensless imaging technology for use in telemedicine could radically transform global health care, has now taken his work a step further -- or tinier: The UCLA engineer has created a miniature microscope, the world's smallest and lightest for telemedicine applications. https://phys.org/news/2010-04-world-smallest-lightest-telemedicine-microscope.html Engineering Thu, 22 Apr 2010 16:03:24 EDT news191170981 Physicists at New York University have developed a technique to record three-dimensional movies of microscopic systems, such as biological molecules, through holographic video.
