Abstract

The essay is based on the control of optical radiation by the interaction of light wave and ultrasonic wave in the medium to complete the acousto-optic modulation communication model and auxiliary measurement systems based on the Bragg diffraction. The travelling wave acoustooptic switch based on Bragg diffraction is the core of the acousto-optic modulation communication experimental device. The LD is used as the source of light and the Optical fiber is connected to the light path, which accomplishes the application of light fibre in the Acousto-optic communication. The CCD light strength detector auxiliary measurement systems is designed in the modulation. The system is combined with the oscilloscope to observe the distribution of light intensity directly, which is convenient for modulation and increase the accuracy of measurement. This system can be used in the experiment of Bragg diffraction,acousto-optic modulator,acousto-optic communication.
