Dark current spectroscopy

WebDark current is caused by thermally generated electrons, which build up on pixels regardless of whether the sensor is exposed to light. Dark current noise is the charge generated from dark current and is common across all sensor types but can be reduced by deep cooling of the camera. WebDark-current spectroscopy can be used to determine the defects present by monitoring the peaks in the dark current histogram's evolution with temperature. Dark current is one of the main sources for noise in image sensors such as charge-coupled devices.
