Abstract

Multi-spectral IR, coupled with advanced image processing procedures, offers the possibility of wide area surveillance and the detection of low concentrations of chemical vapors. A field experiment was performed using the ARPA Multi-Spectral IR Camera sensor mounted on an aircraft. The sensor aircraft flew over a controlled diethyl ether release in a tropical rain forest acquiring image data from both 10000 ft and 22000 ft altitude. The data was processed using multi-spectral algorithms and the vapor was detected over both an open area and the rain forest canopy. This detection was made possible by the removal of most of the background scene by multi-spectral processing.
