Spatial Heterodyne Surface Chemical Agent Detector (SHSCAD)
Capability Description: Wide area, high areal coverage rate surface contaminant detection via LWIR reflectance spectroscopy employing eye safe broadband quantum cascade lasers (QCLs) and a high-speed spatial heterodyne spectrometer (SHS) in a handheld sensor package (~ 10,000 cm3, 10 lb) .
- A broadband QCL array transmitter that provides continuous coverage over 1000-1300 cm-1 used for flying spot illumination,
- A high throughput SHS snap shot receiver,
- An automated chemical target detection algorithm employing a variant of subspace (S-)ACE optimized for the discriminant SNR level and operation in a cluttered environment
Benefit to Warfighter: The SHSCAD platform supports force protection capability for FOBs and entry point control
