The program has as its goal the development of video detection techniques which are appropriate for the millimeter and submillimeter range of the spectrum. Measurement of the sensitivity of the TGS pyroelectric effect detector indicates a minimum detectable signal level of approximately 4 microwatts. Additional studies on the theory of the reflecting beam waveguide indicate that at least two reflector shapes are permitted by the approximate theory developed for the analysis. If any differences in the electromagnetic fields corresponding to these two types of reflectors exist, they are obscured by the approximations made in the analysis. Author
