    Material identification by plasmonic infrared microspectrometer employing machine learning
    Meng, J ; Weston, L ; Balendhran, S ; Wen, D ; Cadusch, JJ ; Unnithan, RR ; Crozier, KB (Optica Publishing Group, 2021-01-01)
    We demonstrate a microspectrometer comprising plasmonic filters integrated with an infrared camera. Blackbody light illuminates the material being studied, with transmitted light collected by the microspectrometer. The latter uses machine learning to identify the material.
