Abstract :
Measurements of 60 Hz high voltages with a technique based on electric field modulated laser interference figures (produced by passing laser light through a solid sphere of electrooptic crystal) are discussed. The spherical geometry automatically forms a laser interference figure, and results in less electric field distortion than the geometries of previous electrooptic sensors in a uniform electric field. A proof-of-principle experiment was performed using a LiNbO/sub 3/ spherical electrooptic sensor.<>
