A novel method of thermal imaging based on the up-conversion of infrared radiation in nonlinear optical crystals is analyzed. An equation is derived giving the temperature resolution in terms of the pump laser energy E(p). For a proustite-ruby system

The sensitivities of heterodyne and direct-detection systems at CO2 laser wavelengths are compared to illuminate the design principles involved. It is shown that destruction of the temporal coherence of scattered radiation is a significant effect whe

The ability to superimpose arbitrary modulation waveforms on a CW laser beam makes the acoustooptic modulator suitable for an important task: to apply modern microwave radar electronic signalprocessing and signal-generation techniques to heterodyne C

For specially prepared `bar diode' tunnel diode junctions that consisted entirely of germanium, it was found that uniaxial compressional stresses applied to the junction caused reversible changes in the peak and valley currents. The changes were line

At room temperature high-purity synthetic single crystals of proustite were found to conduct electricity predominantly by motion of Ag+ ions; their transport number is 102±002. Evidence from photoconductivity observations shows that electronic condu
