ABSTRACT:
A spectral filter includes a two-dimensional array of Fabry-Perot cavity structures, a controller, and a sampling circuit used to switch the Fabry-Perot cavity. The filter receives an incoming image, the sampling circuit switches the cavity to generate a filter image, and the filtered image is detected by the photodetectors to convert a filtered image into digital data. The controller coordinates all the image capture functions of the spectral filter.
