Paper Abstract

There is a growing need for passive sensors capable of detecting low concentrations of various gasses at long ranges (> 1 km). An electro-optical (E0) technique is described which uses small changes in the temporal coherence of natural light caused by the gas as the means of detection. The theoretical principles are described and the results of recent experiments to detect nitrogen dioxide (NO2) are presented.
