ACTIVE PIXEL SENSOR

ACTIVE PIXEL SENSOR. TECHNOLOGY. HEMAKUMAR.B. 1D or 2D array of photosensors can record optical images projected onto it by lens system. Individual photosensor in an imaging array is called pixel ( pict ure el ement). High image resolution requires small pixels.

COS signal to noise capabilities

Limitation of COS S/N No good 2-D flat available. Fixed pattern noise dominates COS spectra. An uncalibrated COS spectrum is affected by: Optical response Smooth F ixed in wavelength space (sort of) Fixed pattern noise Due to detector irregularities
