Paper Abstract

A new approach to the remote electro-optical detection of gases is presented. Radiation, of greater spectral width than an absorption line or series of lines, is analysed using an interferometer. Absorption strength is then deduced from features of the temporal coherence function. Theory and preliminary experiments are discussed.
