晶体声光衍射效应中声致折射率变化研究
The Study of Refractive Index Increment on the Ultrasonic Grating Experimentation
摘要
Abstract
Acousto-optic diffraction intensity caused by acoustic refractive index change is analyzed.In order to further define the refractive index change of the acoustic-optic effect, based on TeO2 acousto-optic medium experiment., the intensity distribution of the diffraction spectrum is analyzed by CCD, the light meter image and computer processing to get relative intensity of diffraction spectrum in the different frequency.The refractive index increment is obtained by the comparative numerical calculating value on the different ultrasonic frequency.关键词
