Optical flow — The optic flow experienced by a rotating observer (in this case a fly). The direction and magnitude of optic flow at each location is represented by the direction and length of each arrow. Image taken from.[1] Optical flow or optic flow is the… … Wikipedia
Optical flow sensor — An optical flow sensor is a vision sensor capable of measuring optical flow or visual motion and outputting a measurement based on optical flow. Various configurations of optical flow sensors exist. One configuration is an image sensor chip… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia
Optical IP Switching — (OIS), is a novel method of creating transparent optical connections between network nodes using a flow based approach. An IP flow is a collection of IP packets going from the same source to the same destination: the exchange of IP packets is the … 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 mapping — Optical mapping[1] is a technique for constructing ordered, genome wide, high resolution restriction maps from single, stained molecules of DNA, called optical maps . By mapping the location of restriction enzyme sites along the unknown DNA of an … 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 pumping — of a laser rod (bottom) with an arc lamp (top). Red: hot. Blue: cold. Green: light. Non green arrows: water flow. Solid colors: metal. Light colors: fused quartz. Refs: [1], [2] … Wikipedia
Optical beam-induced currents — Optical Beam Induced Current (OBIC) is a semiconductor analysis technique that employs a scanning laser beam to induce a current flow within a semiconductor sample which may be collected and analyzed to generate images that represent the sample s … Wikipedia
optical Doppler tomography — optical coherence tomography in which shifts in frequency caused by interaction between the infrared waves and moving particles in tissue are used to measure the particle velocities (e.g., in the imaging of blood flow), based on the principle of… … Medical dictionary
Flow visualization — In fluid dynamics it is critically important to see the patterns produced by flowing fluids, in order to understand them. We can appreciate this on several levels: Most fluids (air, water, etc.) are transparent, thus their flow patterns are… … Wikipedia
