Laser Photoacoustic Detection Of Explosive Vapors

TLDR: The Aerospace Corporation under contract to the Law Enforcement Assistance Administration (LEAA) is supporting the development of a novel explosives-vapor detector based upon photoacoustic spectroscopy as mentioned in this paper.

Abstract: The Aerospace Corporation under contract to the Law Enforcement Assistance Administration (LEAA) is supporting the development of a novel explosives-vapor detector based upon photoacoustic spectroscopy. This paper reviews the principles and history of the method. The encouraging progress to date, obtained through subcontracted programs that characterized explosives vapors and environmental species and that measured photoacoustic absorption coefficients of selected explosives vapors and pollutants, is briefly described© (1977) COPYRIGHT SPIE--The International Society for Optical Engineering.
