摘要： A system and method of calibrating optical measuring equipment includes optically measuring discrete objects of a first known predictable pattern from a calibration apparatus, wherein the first known predictable pattern is a bit pattern. A recording surface optical reader is calibrated based on the optically measuring. Using the first known predictable pattern, contamination is filtered from the results of the optically measuring.
