Abstract
Inspection and verification of configuration of a bent tube is achieved by placing the tube upon a conveyor that moves past a pair of mutually orthogonal optical scanners. Interruptions of a light beam at boundaries of the passing tube are used together with the known beam scan pattern and the known position of the conveyor in the course of its movement to generate signals that define coordinates of vertical and horizontal projections of the tube boundary. From these coordinates the desired tube data can be determined and compared with a reference, thereby comparing tube configuration with a reference configuration.
