Coherent or Heterodyne Detection,e wave except in the value of the quantum energy and the wavelength or frequency cutoff of the photon detector. We now consider heterodyne or coherent detection first demonstrated at optical frequencies by . et al. (1955). By using a single-frequency local oscillator as a reference, we may convert t

Thermal Detection, direct photoexcitation process. Because detectors of this type have no inherent long-wavelength cutoff and the sensitivity limitation is mainly due to the thermal background power, we shall first investigate in detail the fluctuations of the thermal radiation field. To this point, we have assumed t

The Effects of Atmospheric Turbulence,the sensitivity, in terms of the background power. In addition, aerosol and molecular scattering are particularly important background sources in the visible region of the spectrum, because of the sun’s radiation. Detailed data on absorption and scattering may be found in . (1965) and in the RCA .,

Detection Statistics,g the relationship between this measure and the operating characteristics of the system. In this section, we shall treat the properties of the detection process that are particularly important for a radar or communications system. These are the probability of detection .. and the probability of erro
