    We proposed and experimentally studied a technique of vibration object monitoring. The technique is based on self-diffraction of the speckle pattern on the adaptive correlation filter recorded in photorefractive Bi[sub 12]TiO[sub 20] crystal. This filter is recorded owing to the light-induced...
