ABSTRACT:
A method and apparatus based on the exploitation of quantum effects related to stimulated emission for detecting the presence of aircraft or missile exhaust plumes in the atmosphere. In the preferred embodiment, the present invention is directed toward detecting electromagnetic radiation due to the presence of chemical compounds existing in the exhaust plume which occur in areas of the spectrum not normally interrogated; that is, in the regions of 0.2-200 microns and 1 KHz-1000 GHz.
