Physical Sciences Inc. (PSI) has been awarded a research program from the U.S. Army to develop a novel multi-path extinction detector (M-PED) for the identification and quantification of aerosol and vapor phase chemical warfare agents and toxic industrial chemicals.

PSI’s M-PED simultaneously measures spectral extinction within an open path optical cell across multiple pathlengths in a single microbolometer frame. The resulting 2D data matrix is fit to Beer’s Law to identify and quantify chemical concentration. M-PED is projected to meet the Aerosol Vapor Chemical Agent Detector (AVCAD) performance specifications for aerosol and vapor sensitivity, unit size, weight, power and cost.

PSI’s M-PED will provide sensitive quantification of CWA and TIC vapors and aerosols in a compact instrument. As such, the M-PED will have application to a variety of defense, security and industrial applications. This technology will further provide the capability to validate models of compliance, safety, health, and industrial/medical process monitoring.
