Noise-equivalent power — (NEP) is a measure of the sensitivity of a photodetector or detector system. It is defined as the signal power that gives a signal to noise ratio of one in a one hertz output bandwidth.[1] An output bandwidth of one hertz is equivalent to half a… … Wikipedia
Noise equivalent temperature difference — (NETD) is a measure of the sensitivity of a detector of thermal radiation in the infrared, terahertz radiation or microwave radiation parts of the electromagnetic spectrum. It is the scene temperature difference equal to either the internal noise … Wikipedia
Noise-equivalent temperature — (NET) is a measure of the sensitivity of a detector of thermal radiation in the infrared, terahertz or microwave portions of the electromagnetic spectrum. It is the amount of incident signal temperature that would be needed to match the internal… … Wikipedia

Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… … Wikipedia
Microchannel plate detector — from the Daresbury Recoil Separator A micro channel plate (MCP) is a planar component used for detection of particles (electrons or ions) and impinging radiation (ultraviolet radiation and X rays). It is closely related to an electron multiplier … Wikipedia
Canny edge detector — The Canny edge detection operator was developed by John F. Canny in 1986 and uses a multi stage algorithm to detect a wide range of edges in images. Most importantly, Canny also produced a computational theory of edge detection explaining why the … Wikipedia
Electrolytic detector — The electrolytic detector, or the bare point electrolytic detector as it was also called, was a type of wet demodulator used in early radio receivers. This form of detector was in extensive use, and was very sensitive and reliable.HistoryWhile… … Wikipedia
