“…The ratio 'signal"noise is: (6) = J a0j2/ja°j2 = (J3bo2sin2qilN)2K1 ,1K22 (6) where K22 is major absorbing axis. Equation (6) can be transformed: 'signaif'noise = (13 ,sin2p/N)2K1 ,/K22 (7) where 13 = r14n03k0zF1, and F1 -yEd/(1 + iEd/Eq).…”

Highly efficient diffractive grating based on doped photorefractive crystal sillenite family have been observed without application of external electric field. The diffractive efficiency of the doped crystal is discovered 700 times as much as that of the undoped crystals. The space frequency greater than 1 1363 lines/mm and response time of 70 msec using low power CW laser have been achieved. 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 (seifreconstruction) of this grating to external influence fields ( vibration, temperature, electric, optic etc.) allows creation of a new optical developments of small size diffractive dynamic elements -DDE in contemporary optical engineering. Applications of DDE to microinterferometry, single beam microcorrelators, precision targeting have been presented.
