Chapter 1 Infrared DetectorCharacterizationOver the past several hundreds of years, optical systems (telescopes, microscopes,eyeglasses, cameras, etc.) have formed their optical image on the humanretina, photographic plate, or film. The birth of photodetectors dates back to1873 when Smith discovered photoconductivity in selenium. Progress wasslow until 1905, when Einstein explained the newly observed photoelectriceffect in metals, and Planck solved the blackbody emission puzzle byintroducing the quantum hypothesis.
During the 1950s, IR detectors were built using single-element-cooled lead salt photodetectors, primarily for anti-air-missile seekers. Usually ... After the invention of CCDs by Boyle and Smith,5 the idea of an all-solid-state electronically scanned 2D IR detector array caused attention to be turned to Infrared Detector Characterization 3.
