Claim 10:
11. An optical correction system for correcting display of images on a display panel having pixels, the system comprising:
an optical measurement device arranged to optically measure the display panel;
an optical processing circuit coupled to said optical measurement device adapted to
display one or more calibration patterns on the display panel while capturing one or more calibration images of said calibration patterns with said optical measurement device, said one or more calibration patterns comprising a pattern of coarse features and a pattern of fine features, an average spatial density of the coarse features less than an average spatial density of the fine features;
locate images of the fine features within the calibration images with use of the images of the coarse features in the calibration images; and
generate correction data for correcting images displayed in the display panel with use of the located images of the fine features.
