Original Abstract Submitted

fiducial patterns that produce diffraction patterns at a camera sensor are etched or otherwise provided on the surface of a cover glass (cg) in front of a camera. an active light source injects light into the cover glass or into a diffractive optical element to strengthen the signal from the fiducial pattern, or alternatively an active light source is used to reflect light off a reflective fiducial pattern on the cover glass, thus requiring fewer frames to capture and process the diffraction pattern caused by the fiducial pattern.
