  • Patent number: 3941484
    Abstract: A high-speed technique for making accurate dimensional measurements of objects without physically touching the objects. The technique involves generating a low-divergence, collimated light beam which acts to silhouette the object to be measured to produce an image thereof that can be viewed and analyzed by a programmed electro-optical scanner in a manner yielding highly accurate dimensional information substantially independent of the location of the object relative to the viewer.
