US Patent Issued to Massachusetts Institute of Technology on June 23 for "Pixel scale Fabry Perot filter array for chemical agent vapor detection" (Massachusetts Inventor)

ALEXANDRIA, Va., July 15 -- United States Patent no. 12,663,312, issued on June 23, was assigned to Massachusetts Institute of Technology (Cambridge, Mass.).

"Pixel scale Fabry Perot filter array for chemical agent vapor detection" was invented by William Lawrence (Medford, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Fabry-Perot filters having different cavity thicknesses are formed in arrays on a substrate for spectral sensing. The filter array can be coupled to a detector array to make a compact, low size, weight and power spectral sensor that detects spectral information in a scene viewed by the detector array. The spectral sensor can be used in a compact spectrometer to detect the presence of ha...
