DBC Technology Corp. — Department of Defense SBIR Phase I: A new and promising algorithm is proposed based on hyperspectral unmixing by a sequential

Description

A new and promising algorithm is proposed based on hyperspectral unmixing by a sequential processor that will be further developed for data fusion to both enhance sensor sensitivity and eliminate the need for separate background interrogation, thereby allowing for fast real time detection. Sensor sensitivity will be improved by a combination of passive FTIR spectroscopy, and active thermal imaging, with pulsed illumination from an advanced, compact CO2 laser with proven tunability over 120 isotopic wavelengths. The objectives of the Phase I program are to prove the essential elements of the advanced algorithm supported by acquisition of new field data and to develop an integrated sensor architecture based on the results. The new active/passive sensor will have the capability to detect surface contaminants, airborne biological particles, and chemical vapor and aerosol agents making possible detection of a large number of agent types with a single sensor.
