Abstract

A system and method for measuring the physical characteristics of an object is provided, wherein the method includes disposing the object within the sensor optical path of an inspection system, causing a source collimated light beam to propagate along the source optical path to be at least partially incident upon the reflecting device, reflecting the source collimated light beam to create a reflected collimated light beam that propagates along the sensor optical path such that the reflected collimated light beam is at least partially incident upon the object to produce a silhouette, wherein at least a portion of the silhouette is incident upon the sensing device to generate initial image data responsive to the silhouette and processing the initial image data responsive to at least one predetermined algorithm to generate resultant image data responsive to at least one of a plurality of physical characteristics of the object.
