Abstract
A method for increasing the pixel count delivered from a plurality of light detectors when scanning an object that includes positioning a mask, having a plurality of two dimensional Walsh-Hadamard filter patterns, in front of a plurality of light detectors to control the passage of light through the mask filter patterns to the light detectors. The method also includes positioning a lens assembly in front of the mask to project an image through the mask filter patterns on to the plurality of light detectors. The method also includes moving the mask, plurality of light detectors, or the image in a plane defined by a planar surface of the plurality of light detectors. The method also includes measuring the filtered image projected through the mask with the plurality of light detectors.
