ABSTRACT:
This invention relates to the electro-optically based sensor units of use in measuring the "fit up" of panels as on car bodies, aircraft, etc. The disclosed invention is capable of measuring both the gap between the adjacent panels and their relative positions to obtain the width of the gap, the location of the edges of the panels can be estimated by fitting curves to the measured data, or "flushness", in the direction out of plane. Embodiments include a hand-held portable unit capable of being used on finished assemblies such as car bodies, and aircraft sections, as well as on "ring" gages in which a single test panel is checked relative to a reference frame or "ring".
