We first consider the fundamental principles of detection, then the noise associated with the detection process, and, finally, analyze two limiting forms of detection, signal-noise limited and background-

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

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

We shall here give a general treatment of the noise limitations in a laser preamplifier and show that the ultimate signal-to-noise performance is almost i
