  TDI Sensor: Introduction TDI detector refers to Time Delay Integration, which has a distinct detector readout mode that is used for observation of high-speed moving objects under low light conditions, generally undetectable by classic CCD array TDI mode offers increased responsivity for imaging applications, as compared to other video scanning methods, by allowing greater scanning speeds in low light and produces crisp image Major benefits offered by the TDI sensor include high speed, low cost of operation, immune to reflections, high quantum efficiency, high resolution, and wide imaging areas TDI sensors market are utilized in applications that require both high speed and high sensitivity such as inline monitoring, inspection and guidance, sorting, and earth observation satellite (weather observation) Traditionally, CCD systems were used for TDI sensors; however, presently, several companies are developing new solutions that combine CCD pixels and CMOS readout in one technology...
