Abstract : Narrow-band detection of optical signals over a large field of view wherein the selective reflecting power of metallic vapors is employed. A modulated carrier signal to be detected is directed to a Brewster window of an enclosure containing a vapor such as mercury. Only the incident light of interest is reflected through an exit window and detected by means of a photo-multiplier.
