Abstract
A method and apparatus for inspecting the contour of an article is disclosed. Nondestructive viewing techniques including the projection of a light pattern onto the article to be inspected and the imaging of said light pattern to a display screen are discussed. The concepts taught enable the viewing of article regions which were formerly obstructed in conventional viewing systems.
