Abstract

We present original results of an investigation of the specific features of optical electrochirality (electrogyration) in a lead tungstate crystal. Since this crystal exhibits neither the Pockels effect nor the inverse piezoelectric effect, the electrogyration effect can be used to create a fast-response electric sensor for remote monitoring of high-speed processes in high-voltage electric networks. A fiber-optic sensor prototype has been manufactured using optical elements intended for fiber communications.
