How does a charge coupled device work
WebAug 1, 2012 · Charge transfer device detectors are often, but not always, cooled to sub-zero temperatures. This is usually done via a Peltier cooling device. CCDs and CIDs are semiconductor devices and will exhibit background signal noise, called ‘dark current’, when the detector is not exposed to any light source. WebThe term charge-coupled device actually refers to the method by which charge packets are moved around on the chip from the photosites to readout, a shift register, akin to the …
