Abstract
Disclosed is a stereoscopic optical inspection system. A computer uses the stereoscopic information to compute and correct for angular and distance misalignments between the unit-under-test and the inspection system. A feature of the optical system is the use of multiple high-resolution inspection cameras, in conjunction with a single stereoscopic reference camera. One example of a preferred embodiment is presented as an electro-optical inspection system for inspection and/or alignment of cathode-ray-tube displays and other video displays on a production assembly line.
