Abstract
Disclosed herein is a system having an optically transparent substrate having a first side and a second side that are opposed to each other, a microprocessor, a database, a camera disposed upon the first side of the optically transparent substrate and a source of illumination. The source of illumination is disposed in a ring around the camera on the first side and is operative to illuminate the object disposed on the second side of the optically transparent substrate. Further the camera is in operative communication with the microprocessor and the database. The camera is operative to capture an image of an object disposed upon the second side of the optically transparent substrate. The microprocessor is operative to calculate dimensions and geometry of the object from the image and facilitate acceptance or rejection of the object based upon a standard, a parameter or a calibration chart.
