Applications of Photodiodes:?
In scientific research and industry, photodiodes are basically used to accurately measure the intensity of light, as they provide better linearity and more precise results than other light-conducting materials.?
Photodiodes are also used in a wide range of indispensable applications in medical devices such as X-ray computed tomography (CT) scans and pulse detectors, among a host of other commonly used instruments.
PIN junction photodiodes are not typically used to measure very low light intensities. Avalanche photodiodes, photocouplers, and photomultiplier tubes can be useful for applications such as astronomy, spectroscopy, night vision, and laser rangefinders, assuming that low-light conditions necessitate the use of a high-sensitivity detector.
