Paper Abstract

Sensitive and rapid measurements of the absorption and dispersion associated with narrow spectral features are accomplished using frequency modulation (FM) spectroscopy. The absorption or dispersion is measured by detecting the heterodyne beat signal which occurs when the FM spectrum is distorted by the spectral feature of interest. Experimental results are presented.
