Selected Applications,in one experiment several of the fundamental concepts developed in the text. These include the thermal-radiation field fluctuations of Chapter 7 and the target-scatter properties discussed in Chapter 10.

Vacuum Photodetectors,increases, the available quantum efficiency rises to as high as 20 to 30% from 0.5 μm into the ultraviolet. Beyond 1 μm wavelength, the choice of detector is limited to semiconductor devices, if the ultimate in sensitivity is to be approached.

Both incoherent and coherent detection are treated in a unified manner, after which selected applications are analyzed, following an analysis of atmospheric effects and signal statistics. The material was developed during a one-s

Social Policy in a Development Contextr over the detector surface. We then derive two important theorems that are applicable to heterodyne detection. These are the antenna theorem, which describes the angular response of the detector, and the mixing theorem, which allows the calculation of the mixing efficiency at any arbitrary surface.

The Effects of Atmospheric Turbulence,ently been reviewed by . (1975). We shall here give a simple one-dimensional treatment based upon the work of . (1967a). In the first section, we find the limitation on effective aperture area in a heterodyne system and in the second, the minimum field of view allowed for an incoherent detector.
