41Optical 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… …
42Optical physics — Optical physics, or optical science, is a subfield of atomic, molecular, and optical physics. It is the study of the generation of electromagnetic radiation, the properties of that radiation, and the interaction of that radiation with matter,… …
43Optical 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,… …
44Optical performance monitoring — (OPM) is used for managing high capacity dense wavelength division multiplexing (DWDM) optical transmission and switching systems in Next Generation Networks (NGN). OPM involves assessing the quality of data channel by measuring its optical… …
45Optical 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 …
46Optical engineering — is the field of study that focuses on applications of optics. Optical engineers design components of optical instruments such as lenses, microscopes, telescopes, and other equipment that utilizes the properties of light. Other devices include… …
47Optical Carrier transmission rates — are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks.[1] Transmission rates are defined by rate of the bitstream of the digital… …
48Optical phase space — Optical phase diagram of a coherent state s distribution across phase space. In quantum optics, an optical phase space is a phase space in which all quantum states of an optical system are described. Each point in the optical phase space… …
49Optical fiber, nonconductive, riser — (OFNR) is a type of optical fiber cable. As designated by the National Fire Protection Association (NFPA), this name is used for interior fiber optic cables which contain no electrically conductive components, and which are certified for use in… …
50Optical wireless — is the combined use of optical (optical fibre) and wireless (radio frequency) communication to provide telecommunication to clusters of end points which are geographically distant. The high capacity optical fibre is used to span the longest… …
