1. A method for increasing the pixel count delivered from a plurality of light detectors when scanning an object, comprising: 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; 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; moving the mask, plurality of light detectors, or the image in a plane defined by a planar surface of the plurality of light detectors; and measuring the filtered image projected through the mask with the plurality of light detectors.
