Abstract
The availability of tunable line sources such as diode lasers in the infrared have lead to the development of two new forms of spectroscopy. The first one is passive heterodyne detection, a form of amplitude detection where the spectrum is scanned by tuning a local oscillator, in this case a diode laser. A second development is using a diode laser as a tunable source to scan the absorption spectrum of a sample with detection by the usual power detector. The capability of the first technique will be compared with spectral discriminators of the classic type using power or direct detection. The second technique will be compared with Fourier Transform absorption spectroscopy using a high temperature blackbody as a source.
