Original Abstract Submitted
fiducial patterns that produce 2d barker code-like diffraction patterns at a camera sensor are etched or otherwise provided on a cover glass in front of a camera. 2d barker code kernels, when cross-correlated with the diffraction patterns captured in images by the camera, provide sharp cross-correlation peaks. misalignment of the cover glass with respect to the camera can be derived by detecting shifts in the location of the detected peaks with respect to calibrated locations. devices that include multiple cameras behind a cover glass with one or more fiducials on the cover glass in front of each camera are also described. the diffraction patterns caused by the fiducials at the various cameras may be analyzed to detect movement or distortion of the cover glass in multiple degrees of freedom.
