Abstract

It is proposed to combine the real-time testing of the dynamic holographic grating with self-diffraction registration of this grating in Raman-Nath conditions in order to detect the photorefractive variations which accompany the proton transport through the rigidly-held fragments of purple membranes containing biological photoreceptor bacteriorhodopsin (BR). The properties of superfast holographic recording on BR-films in Raman-Nath conditions are applied for an analysis of the object motion with cycle processing time of less than 1 ms. Whereas most of the holographic methods are based on dynamic holography recording in photorefractive materials with local response in Bragg conditions. The analysis of the object motion in the first-order diffracted beam in Raman-Nath self-diffraction conditions offers a number of advantages: 1 ) there is not the problem of the suppression of high undiffracted beam; 2) the registration of start and final of a object motion with very high precision; 3) the separation of the forward and reverse motions, even after a time it is possible to detect what motion direction was initial; 4) the low-frequency and high-frequency components of a object motion are selected and their mutual direction are determined.

Keywords: biological photoreceptor bacteriorhodopsin (BR), polymer films with BR, proton release, Raman-Nath self-diffraction conditions, first-order diffracted beam, analysis of the object motion, motion direction separation, motion frequency selection.
