摘要
A method of controlling the Bragg angle for the anisotropic Bragg diffraction of light by means of a change in the refractive indices of an anisotropic medium is discussed. The possibility of using this effect for light modulation and also for Bragg angle correction in ultrasonic diffraction light deflectors, thereby greatly improving the characteristics of these deflectors, is shown. The results of a test of a lithium niobate deflector with Bragg angle correction, accomplished with an electrical voltage applied to the crystal, are presented.
