It is shown that the qualitative and quantitative characteristics of acousto-optical cell in which Bragg diffraction realized, determined kinematic parameters of the ultrasonic beam. Characteristics of ultrasonic field defined transfer characteristic electroacoustic transducer that generates ultrasonic waves in optically transparent crystal. A scheme of constructing models electrode structures for cell electro-acoustic transducer. Для создания монолитного дефлектора световых лучей было предложено использовать пленочные структуры на основе наностержней ZnO и инициированную в них дифракции Брэгга. Для формирования наностержней ZnO был выбран комбинированный гидротермальный метод, который отличается гибкостью процесса, простотой реализации, низкой стоимостью и позволяет на первой стадии формировать зачаточную пленку с помощью золь-гель метода из раствора на основе ацетата цинка, а на второй стадии нарастить массив наноструктур из раствора на основе нитрата цинка. Для осаждения зародышевой пленки на подложку использовался метод центрифугирования при 3000 об / мин в течение 30 с. This technology allowed to obtain a multilayer structure with a homogeneous and stable film. As a working layer of ZnO nanorods were synthesized with a diameter of 30-60 nm and a length of 0.6 m, which increased the surface area and thus the sensitivity of the transducer. Calculation of the optimum frequency response of the system was implemented by using the approximation given frequency characteristics of the final complex Fourier series, allowing to link the length of each electrode through the weights with a member of the Fourier series, and change the frequency patterns into account through the Legendre polynomials. Optimized design deflector light rays using diffraction Bragg. Operating methods for control and management of spatial distribution of kinematic field characteristics and frequency response parameters deflector. A sample deflector light rays using diffraction Bragg resonators based on lithium niobate substrate (128 ° YX-LiNbO3). The calculation of the transducer at a frequency 433.92 MHz, allowing the use of such design in the "integrated sensor systems."
