Scientific paper

High-performance infrared detectors such as arsenic-doped silicon (Si:As) and bismuth-doped silicon (Si:Bi) have been successfully used in ground-based infrared telescope systems in the 2- to 20-micron range. Optimum performance (background photon noise limited operation) of these detectors is obtained by using a special feedback amplifier. The advantages of such a system are discussed in conjunction with preliminary data on Si:As and Si:Bi detectors.
