Abstract

The extreme dynamic range (XDR) program performs a pre-exposure and uses a classification structure for the determination of the signal’s patterns and intensities in a star-field. Using this and the unique architecture of Thermo Fisher Scientific CID821 image sensor the signals were targeted and properly monitored throughout the main exposure. This allowed for a single exposure with high DR and a collection of signals that are typically ignored and saturated. This approach takes full advantage of the CID821 image sensor’s abilities.
