Dark current: the ideal case - mwcraig.github.io

WebNov 30, 2024 · Typically the electronics of the camera introduce interference into the circuitry, resulting in noise when the signal is read. Dark current noise is caused by heat that builds up in the sensor as it is being read. This noise is dependant on the time of the exposure (more heat build up over time) as well as the ambient conditions. ... WebJan 22, 2024 · The measured S n embraces several unknown sources.
