Abstract
A method for detecting particulate contamination under a workpiece fixtured by a calibrated material handling system includes performing 3D measurements of a workpiece at multiple of positions to construct a 3D map of the workpiece, calibrating the 3D map by comparing a pre-computed calibration map to the 3D measurements, and detecting particulate contamination by processing the calibrated map.
