Paper Abstract

Highly efficient diffractive grating based on doped photorefractive crystal Bi12TiO20 have been applied for measurement of displacement after mechanic and temperature loading without application of external electric field. The diffraction efficiency of the doped crystal is discovered in non-optimized optical set up 100 times as much as that of the undoped crystals. Practically unlimited number of grating cycles of write, erase and read have been performed without optical damage and external electric or temperature fields. High adaptivity of this grating to external influence fields allows creation of a new optical development of small size diffractive dynamic elements -- DDE in contemporary optical engineering.
