Athena

Hyperspectral Infrared Cameras for the MWIR and LWIR spectral regions

Two units were built.  One covered the spectral region of 3 to 5 microns  and second covered the spectral region of 8 to 11 microns.  The lenslet optical arrays and actuation system were embedded in the closed cycle dewar and collected full hyperspectral data cubes. 

Significance of this achievement

Embedding the optics and mechanical actuation system in the cold stage of a closed cycle miniature dewar system was a significant challenge and PAT  demonstrated that successfully. To our knowledge this has not been done in such a small package before now.

Test

Athena was field tested and demonstrated that hyperspectral imaging using lenslet arrays can detect and identify gas phase chemical warfare agent from a standoff range of 1 Km. 


This work lead to a follow-on program to build a prototype system, Helios, to mount on a miniature drone.
