Paper Abstract

In this paper, we summarize the design and preliminary performance evaluation of a new raster-scanning BAGI imager that is intended for long-range operation, at a target range of 300 m. A system capable of imaging at this range is desired to make airborne gas imaging from a low-flying airplane or helicopter possible. The system uses a 20 W CO2 laser and a redesigned scanner that employs telescopic transmission and receiving optics. Model predictions of the performance of the new system and some recent field testing results are presented. Issues relating to gas imaging at long ranges are also discussed.
