In holographic methods of vibration registration a key role belongs to dynamic photorefractive materials. Polymer films with fragments of purple membranes containing biological photoreceptor bacteriorhodopsin (BR) have attracted a lot of attention as a dynamic photorefractive material in recent years. In this work, we propose the application of holographic gratings recording resulting from superfast photorefractive mechanism in BR-films for efficient vibrations registration in Raman-Nath self-diffraction conditions. It is shown that this holographic method enables the registration of start and final of vibration with very high precision. The selection of forward and reverse motions is performed by means of this holographic method.
