Paper Abstract

Gas monitoring over long distances using Frequency Modulation (FM) spectroscopy require phase insensitive detection scheme because of the severe scintillation problem. We report our effort to develop a long working distance CO2 monitoring LIDAR that uses phase insensitive Two-Tone Frequency Modulation (TTFM) spectroscopy technique. We could detect 10-4 single pass absorption, and could detect 1ppm CO2 level change in normal air.
