Abstract

The giant volume grating diffraction efficiency of 70% in triple doped photorefractive crystal sillenite family has been observed. Measured signal to noise ratio is more than 250 in continuous hologram registration regime. A high quality interferograms of diffusely scattered objects have been obtained. These results were applied for construction a new adaptive portable sensors for engineering applications.
