Instrumentation for a Fieldable Remote-Sensing CO2 Laser System.

Abstract

A spectrally tunable IR laser transmitter and a 30-cm f/4.0 laser receiver using a (PbSn)Te cooled detector were developed and tested. A design for signal-processing electronics and a system control console were submitted. The Q-switched laser sequentially emits at eight selected wavelengths in a pulse train repeating 100 times per sec. Laser scattered or reflected energy from distant natural targets is collected by the receiver. Absorption characteristics of the return beam are compared with those from potential chemical agents. Signal-processing electronics and a PDP/11 computer identify and measure the concentration of an agent using its unique absorption spectrum.
