Abstract
A portable shock-proof instrument for determining the presence of defects in the surface profile of a container. The instrument includes a portable housing having shock-mounted therein an optical table carrying a point source of light, mirrors for reflecting the light in an inverted U-shaped path thereby providing compactness to the instrument, a lens in the middle portion of the U-shaped path for collimating the light and directing it past an edge of the container thereby producing a shadow image of the edge, a rotating stage for selectively turning the container, a cylindrical telescope for magnifying the horizontal field of view of the shadow image in order to enhance the detection of defects, and a camera for capturing a plurality of shadow edge images as the container is being turned. A processor is connected to the rotating stage and to the camera for analyzing the captured plurality of shadow edge images for the presence of defects.
