The proposed work addresses advanced development of algorithms for chemical detection by DISC and DIAL and extension of the basic approach to mid and long wave IR biological agent detection. The objectives of the six month Phase I program are to process recent field data with current algorithms as a basis for assessment of further algorithm development for detection of all chemical agents and for varying backgrounds, to outline a theoretical approach to biological agent detection using DISC and DIAL in the mid and near IR, to outline parameters for new field test data sets, and to outline modifications of either (or both) the existing Frequency Agile Laser (FAL) sensor and Manportable sensor hardware for collection of field data. The follow-on Phase II work will be directed to performing algorithm development, implementing the necessary sensor modifications, field data collection and data reduction, and assessment of algorithm effectiveness with recommendations for further work. This work will greatly enhance the utility of laser standoff sensors for battlefield military missions, for surveillance of agent production facilities, for homeland defense, and for monitoring commercial production processes. Near term programs that will benefit directly are the Artemis JPO initiative and the U.S. Army ECBC initiative to develop a sensor for manportable and other platforms where size and weight are critical factors.
