Physics of optical holography. Optical holography[1] is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications.
Holography. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
Electron holography is holography with electron matter waves.It was invented by Dennis Gabor in 1948 when he tried to improve image resolution in electron microscope. [1] The first attempts to perform holography with electron waves were made by Haine and Mulvey in 1952; [2] they recorded holograms of zinc oxide crystals with 60 keV electrons, demonstrating reconstructions with approximately 1 ...
Optical mineralogy. A petrographic microscope, which is an optical microscope fitted with cross- polarizing lenses, a conoscopic lens, and compensators (plates of anisotropic materials; gypsum plates and quartz wedges are common), for crystallographic analysis. Optical mineralogy is the study of minerals and rocks by measuring their optical ...
Digital holography is the acquisition and processing of holograms with a digital sensor array, [1][2] typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers three ...
Mineralogy[n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution ...
Specular holography is a technique for making three dimensional imagery by controlling the motion of specular glints on a two-dimensional surface. The image is made of many specularities and has the appearance of a 3D surface- stippling made of dots of light. Unlike conventional wavefront holograms, specular holograms do not depend on wave ...
Yuri Nikolayevich Denisyuk (Russian: Юрий Николаевич Денисюк; July 27, 1927 in Sochi — May 14, 2006 in Saint Petersburg) was a Russian physicist and one of the founders of optical holography in the former Soviet Union. He is known for his great contribution to holography, in particular for the so-called "Denisyuk hologram".
