Abstract:
1. A two-dimensional spectral camera, comprising: a plurality of spectrophotometers, each comprising a Fabry-Perot cavity that includes a pair of Bragg reflectors with a gap between each pair of Bragg reflectors, each cavity designed to capture a pixel from an image, the plurality of spectrophotometers comprising (1) at least one two-dimensional array of spectrophotometers having only Fabry-Perot cavities with an initial size of gap cavity on the order of an ultra-violet wavelength range, (2) at least one two-dimensional array of spectrophotometers having only Fabry-Perot cavities with an initial size of gap cavity on the order of a visible light wavelength range, and (3) at least one two-dimensional array of spectrophotometers having only Fabry-Perot cavities with an initial size of gap cavity on the order of an infrared wavelength range; a light focusing device that focuses incident light; a controller; a sampling circuit; and a compressor that compresses digital data and outputs compressed digital data to an external device, wherein the image comprises incident light reflected from a target, and wherein the controller controls the sampling circuit to sample spectral information from the received light to generate spectral image data, and to convert the sampled spectral information into the digital data.
