• Ray tracing (physics) — In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend …   Wikipedia

• Ray tracing (graphics) — In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane. The technique is capable of producing a very high degree of photorealism; usually higher than that of typical… …   Wikipedia

• Ray (optics) — Ray of light redirects here. For other uses, see Ray of light (disambiguation). In optics, a ray is an idealized narrow beam of light. Rays are used to model the propagation of light through an optical system, by dividing the real light field up… …   Wikipedia

• Optical disc — Optical media redirects here. For transmission media for light, see Medium (optics). The optical lens of a compact disc drive. In computing and optical disc recording technologies, an optical disc is a flat, usually circular disc which encodes… …   Wikipedia

• Ray transfer matrix analysis — (also known as ABCD matrix analysis) is a type of ray tracing technique used in the design of some optical systems, particularly lasers. It involves the construction of a ray transfer matrix which describes the optical system; tracing of a light… …   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 lens design — refers to the calculation of lens construction parameters (variables) that will meet a set of performance requirements and constraints, including cost and schedule limitations. Construction parameters include surface profile types (spherical,… …   Wikipedia

• Optical coherence tomography — Intervention Optical Coherence Tomography (OCT) image of a sarcoma MeSH …   Wikipedia

• Optical imaging — is an imaging technique. Optics usually describes the behavior of visible, ultraviolet, and infrared light used in imaging. Because light is an electromagnetic wave, similar phenomena occur in X rays, microwaves, radio waves. Chemical imaging or… …   Wikipedia

• Optical projection tomography — is a form of tomography involving optical microscopy.[1] It is in many ways the optical equivalent of X Ray Computed Tomography or the medical CT scan. OPT differs in the way that it assumes parallel ray projection as opposed to fan beam… …   Wikipedia
