Narrowband microbolometer arrays for infrared chemical sensing
Agency / Branch:
DOD / ARMY
This Small Business Technology Transfer Research program will develop narrow band plasmonic resonant cavity filters with integrated microbolometer sensors operating in the long wave infrared (LWIR) atmospheric transmission band for IR absorption measurements of low concentration chemicals. IR spectroscopy can identify a wide range of contaminants, including chemical/biological warfare agents, explosives, natural toxins in drinking water, and waste products requiring environmental clean-up. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell's equations. The FEM provides detailed field information, including E field, B field, energy density, and time dependent information with subwavelength resolution, which greatly aids in understanding the underlying physical mechanisms. Test structures will be made using well established nanofabrication facilities, and characterized with spectral and polarization sensitive far field techniques.
