WebThe counts in the image due to sensor glow should grow linearly with exposure time, like dark counts do, but the pixel values are much higher than for pixels whose counts are due to dark current. The top right panel in the figure below shows the part of the CCD near the sensor glow; pixel values are several thousand counts.

WebThese noise terms can be effectively ignored because photon counting is achieved by counting pulses generated from photon and dark events. Thus small fluctuations in pulse … WebThe dark counts in a dark frame are counts and so they follow a Poisson distribution.
