Pacific-Sierra Research Corp. (PSR) will define and develop the design for a feasible man-portable multispectral imaging video system from a proof-of-concept based on modeling and analysis of various hyperspectral exploitation approaches. This portable unit will utilize a high-sensitivity, visible near-through mid-wave IR (VNIR-MWIR) COTS InSb camera operated at a high frame rate, using PSR expertise in VNIR-MWIR multispectral (common aperture) sensor systems. Data rate will be sufficient to generate a real-time false color image. A proposed baseline concept of operation is the pre-selection of 3 spectral band prior to a mission. During utilization, the portable spectral imaging system will operate as a point-and-shoot device, with a small hand-held remote camera head providing optically stabilized color multispectral image on a COTS head mount display unit. PSR will define the requirements for a prototype system. PSR will then develop a lightweight optical, electronics and mechanical packaging concept that can provide an easily assembled imaging sensor with the required spectral imagery and performance capability while remaining inexpensive. Based on the results of this Phase I preliminary design, critical components (i.e., focal plane assembly, bandpass filter) will be defined and the predicted performance evaluated.
