Abstract
An optical technique is described to test large printed circuit boards (PCBs) supporting surface-mounted components. This testing process is based on the change of the light polarization inside an electrooptic material plate. An anisotropic elastomer conductor particular to each type of PCB connects it to the electrooptical material. In a few seconds, high-frequency (100-MHz) signals with a spatial resolution of 1/1000-in. may be tested
