Paper Abstract

We describe the use of cryogenically cooled, extrinsic silicon p+-n-n+ diodes in an unconventional mode of operation as infrared detectors[1], which offer an unusually large dynamic range. The use of these detectors for high dynamic range IR radiometry and IR imaging would require no preamplifiers and could open the way to new means of 3-D processing at or near the focal plane. [2] The detectors perform intensity-to-frequency conversion via circuits with very low power consumption. To our knowledge, these are the only detectors which perform direct IR intensity-to-frequency conversion in the detector itself.
