Abstract: An infrared imaging apparatus having thin-film spatial filters in a stacked array to filter and collate light generated internally by the infrared imaging apparatus such that the light generated impacts a detection area of the imaging apparatus at or near a critical angle. The index of refraction of the detection area being subject to change when irradiated with infrared light such that the amount of light generated internally and reflected to a light detector attached to the imaging apparatus varies with the intensity of the irradiating infrared light.

Abstract: A light transmission structure is provided for use, in conjunction with a light source and detector, for selective detection of biomolecule interactions and/or absorption of infrared light. The light transmission structure includes a substrate having a bottom surface adapted to couple the light source and detector to the light transmission structure, a coupling and enhancing layer disposed on at least a portion of an upper surface of the substrate, a first near-critical angle anti-reflective coating (NCA-ARC) layer disposed on at least a portion of an upper surface of the coupling and enhancing layer, and a second NCA-ARC layer disposed on at least a portion of an upper surface of the first NCA-ARC layer. An upper surface of the second NCA-ARC layer is functionalized and textured so that transmitted incident light is scattered out of the light transmission structure. A difference in refractive index between adjacent NCA-ARC layers is less than about 0.01.
