| Abstract: | A modulation method of light intensity and deflection angle under the Bragg condition based on acousto-optic effect is illustrated in this paper.In a coaxial planar optical system(CPOS),the modulation of laser beams and the light intensity of Bragg diffraction and deflection angle can be achieved by changing the incident angle.The incident angle is the angle between the optically transparent medium and the optical axis,from which the relation between angle and light intensity can be obtained. |
