Frequency-Agile LIDAR Receiver for Chemical and Biological Agent Sensing

Abstract

Objective: Improve standoff range and chem-bio agent detection limits of direct detection LWIR differential absorption LIDAR systems * Standoff range: ~ 2x increase for fixed chem-bio sensitivity; scales as 1/sqrt(NEP) * CB agent sensitivity: ~ 4x increase for fixed standoff range, scales as NEP * Compatible with 200 Hz line-tuned CO2 laser.
