WebDark Shot Noise and Sensor Temperature. As mentioned above, the dark current is a thermal effect and can therefore be reduced by cooling the sensor. Table 1 lists typical … WebMeasurements of dark current as a function of temperature and dark current as a function of reverse-bias voltage were acquired for several packaged detectors. As is described in the following section, dark current is a relatively small electrical current that flows in p-n junction photodetectors when no light is incident on the detector.
WebThe description of the dark current in a CCD is similar to the analysis of the dark current in a diode and requires taking into account several sources of dark current. 4,5. We showed that a model of two exponential functions describes the dark current for the back-illuminated chip accurately. 6. The knowledge of how each individual pixel's WebMar 14, 2016 · The simple answer is that the dark currents are not matched at all. A slightly more (or maybe less) useful answer is that the maximum dark current spec provides a …
