High Speed, Low Temperature Hyperspectral Imager for High Enthalpy Ground Testing

AEDC requires a method to resolve temperature and emissivity across the surface of test articles. Specifically, there is a need for a high-speed low-temperature measurement solution that overlaps with other higher-temperature capabilities. The solution threshold requirements are to measure surface temperature from 0-1500 F (2000 F objective), at 4000 Hz (5000 Hz objective), with a pixel footprint of at most 0.1 inch (0.05 inch objective) and an accuracy of +/- 10 deg F (+/- 5 deg F objective).

Objective

The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items. Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with section 3.5 of the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.

Accurately measure material surface temperature at high speed (5000 Hz +) and low range (0-2000 F) in high enthalpy ground test facilities.

Phase I

Compile low temperature, high sampling rate hyperspectral imager feasibility research that Addresses the solution threshold included in the Description of this topic. Awardee will perform research and present a feasibility report that describes a benchtop proof-of-concept that will be used for fabrication activities during Phase II.

Phase II

Fabricate a well-defined prototype of a low temperature, high sampling rate hyperspecral imager that meets the objectives stated above and can become operationally viable.

Phase III

Hyperspectral imager deployment.
