چکیده
Heterodyne experiments have been performed in the middle infrared using the CO2 laser in conjunction with photoconductive Ge:Cu and photovoltaic Pb1-xSnxSe detectors. The observed minimum detectable power is a factor of five to 25 greater than that for the theoretically perfect quantum counter. The technique should prove useful for infrared communications, radar, and heterodyne spectroscopy. [The SC/ indicates that this paper has been cited over 75 times since 1968.]

Statistical Nature of the Infrared Heterodyne Signal ' ' )
1 HETERODYNE detection is a process which has been used in the radiowave, microwave, 1 and optical regions of the electromagnetic spectrum. Recently, the technique has been extended to the middle infrared as well [I-31. This paper discusses theoretical and experimental considerations related to the signal-to-noise ratio and the statistical nature of the coherently detected signal at the 10.6 pm...

In this paper a method of taking widefield heterodyne interferograms using a prototype modulated light camera is described. This custom CMOS modulated light camera (MLC) uses analogue quadrature demodulation at each pixel to output the phase and amplitude of the modulated light as DC voltages. The heterodyne interference fringe patterns are generated using an acousto-optical frequency shifter (...
