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.

WebMay 1, 2013 · Dark current spectroscopy (DCS) is often used to determine the presence of defects in finished image sensor devices by monitoring the temperature-dependence of peaks in the dark current histograms under different light illumination conditions.23–26. The pattern of different dark currents can result in fixed-pattern noise. WebApr 5, 2024 · The charge generation rate is identified with explicit crystallographic defects within the depletion region. Dark-current spectroscopy can be utilized to decide the imperfections present by observing the peaks in the dark current histogram's advancement with temperature. This dark current is the same that is talked about in PN-Junction studies.
