Before a discussion of the detection process, we first investigate the properties of the optical and infrared radiation in equilibrium with a cavity at temperature T. The results of this derivation are essential to an understanding of detection processes limited by thermal radiation from the vicinity of the detectors as well as from the background or other extraneous radiators near the desired signal source. The treatment also introduces the three forms of thermal statistics which will be used later in discussions of laser preamplification and thermal detectors. A up right finâl concept, introduced in this chapter and developed elsewhere in the text, is that of the allowed spatial modes of the electromagnetic field. The properties of these modes are key elements in the treatment of heterodyne detection and radiation field fluctuations.
