Passive Sensors

The SCRAM sensor represents a single active node in a networked sensor capability that employs the SIGMA architecture to provide persistent wide-area monitoring of chemical warfare agents and toxic industrial chemicals.
AIRIS
The Adaptive Infrared Imaging Spectroradiometer (AIRIS) has been developed for real-time standoff detection of chemical vapors and biological aerosols as well liquids and solids (such as chemical agents and trace explosive residues) on surfaces.
