Abstract
A user-friendly photoacoustic spectroscopy (PAS) system and process (technique) provides an open-field PAS instrument, unit and device to remotely sense explosives, chemicals and biological agents. The PAS system and process can include: a pulsed tunable laser, such as a COlaser, a reflector, such as a parabolic reflector, an acoustic reverberant resonator in which a microphone is installed, and a data acquisition and analysis system.
