Abstract
A high-resolution imaging and processing method and system for increasing the range of a geometric dimension of a part that can be determined are provided. The method includes directing at least one plane of collimated radiation at a surface of the part. Each of the planes is occluded by the part to create unobstructed first and second planar portions of the plane of radiation. Each of the first and second planar portions has a width and contains an amount of radiation which is representative of a respective geometric dimension of the supported part to be determined. The method includes increasing the width and decreasing the intensity of the first and second planar portions imaged on a plurality of predetermined measuring areas to obtain respective elongated planar portions and to produce respective electrical signals. The electrical signals are processed to determine the geometric dimension with enhanced accuracy.
