Hyperspectral Longwave Infrared Focal Plane Array and Camera Based on Quantum Well Infrared Photodetectors

We propose to develop a hyperspectral camera imaging in a large number of sharp hyperspectral bands in the thermal infrared. The camera is particularly suitable for the multispectral thermal infrared (TIR) imager of NASA's HyspIRI Mission. In Phase 1, we successfully developed a crucial camera component: a 640x512 focal plane array (FPA) with 8 - 12 micron broadband longwave infrared spectral response. In Phase 2, we will integrate the FPA with a linear variable filter in a dewar cooler assembly and package the resulting sensor engine with electronics and optics into a camera system. The camera, featuring digital and analog video outputs, will be delivered to NASA at the end of Phase 2 for feasibility testing for the HyspIRI and other NASA missions.

1) Gas sensing (e.g. for the petrochemical industry). 2) Security and surveillance. 3) Thermography. 4) Medical imaging.

1) HyspIRI Mission - Multispectral thermal infrared (TIR) imager. 2) Ground- and space-based astronomy and astrophysics. 3) Chemical/spectral mapping of forests, vegetation, crops, and landmasses. 4) Temperature mapping of oceans and landmasses. 5) Atmospheric mapping. 6) Pollution monitoring.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
