Physical Sciences Inc. (PSI) has been awarded a contract from the Defense Threat Reduction Agency (DTRA) to develop a Spectro-Radiometrically Programmable Infrared Scene Projector (SRP-IRSP) to provide a field calibration capability for longwave infrared (LWIR) hyperspectral imagers (HSIs) performing passive chemical vapor plume imaging.
The SRP-IRSP will specifically enable quantitative simulation of chemical plumes of dynamically commandable radiometric parameters/temperature differentials and mass concentrations in operationally relevant background scenes and release mechanisms. The proposed capability is programmable for the chemical of interest at mass concentrations associated with release of 10 g to >10 kg and can project thermal contrast in both absorption and emission with ∆T of 1-15K. The resulting capability enables calibration, training and validation for LWIR HSIs in an efficient and streamlined manner without the uncertainty and logistics of an actual chemical release.
