Optical tomography — Intervention MeSH D041622 Optical tomography is a form of computed tomography that creates a digital volumetric model of an object by reconstructing images made from light transmitted and scattered through an … Wikipedia
Optical lift — is an optical analogue of aerodynamic lift, in which a cambered refractive object with differently shaped top and bottom surfaces experiences a stable transverse lift force when placed in a uniform stream of light.[1] Contents 1 Discovery 2… … Wikipedia
Optical interferometry — combines two or more light waves in an optical instrument in such a way that interference occurs between them. Early interferometers used white light sources and also monochromatic light from atomic sources (e.g., Young s double slit experiment… … Wikipedia
Optical cross section — or OCS is a value which describes the maximum amount of optical flux reflected back to the source. The standard unit of measurement is . It is dependent on the geometry and the reflectivity at a particular wavelength of an object. Optical cross… … Wikipedia
Optical tweezers — (originally called single beam gradient force trap ) are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch… … Wikipedia
Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… … Wikipedia
Optical astronomy — has two meanings:* In popular culture optical astronomy encompasses a wide variety of observations via telescopes that are sensitive in the range of visible light. Scientists would call this visible light astronomy. It includes imaging , where a… … Wikipedia
Optical sorting — is a process of visually sorting a product though the use of Photodetector (light sensors), Camera[1], or the Human eye[2]. In its simplest operation, a machine will simply see how much light is reflected off the object using a simple… … Wikipedia
Optical contact bonding — is a glueless process whereby two closely conformal surfaces are joined together, being held purely by intermolecular forces. Contents 1 History 2 Explanation 3 Production of an optical contact bond 4 … Wikipedia
Optical format — is a measure of the maximum diagonal size of an imaged object in the focal plane of an optical system. The diagonal size of the imaging sensor (film, CCD or CMOS chip etc.) and the optical format of the lens system must be matched. The optical… … Wikipedia
