Optical current sensors of high values of a current give themselves a wide spectrum of applications for monitoring systems, the control and management in power systems (high-voltage power transmission line), for the metallurgical, chemical, ship-building and defensive industry.

PROM is a typical optically addressed spatial light modulator (OASLM) with photorefractive Bi12SiO20 (BSO) , Bi12GeO20 (BGO) crystals used simultaneously as electro-optic and photoconductive mediums.

PRIZ is optically addressed spatial light modulator (OASLM) with photorefractive BSO, BGO crystals, which crystallographic orientation is cut-111 or cut-110 of polished sides S1, S2 in contrast to PROM devices where longitudinal Pockels effect is used for crystal with cut-100 orientation.
