理论上分析得到声光介质中声致折射率变化导致的衍射光强解析关系式。为了进一步明确声光衍射中声致折射率变化的情况，以及折射率变化量与其他因素的关系，在实验上以二氧化碲为声光介质，使用CCD、光强仪和计算机处理得到各级衍射光谱的相对强度，得出不同声频率下的声致折射率变化量，同时研究了超声频率对折射率变化量的影响。

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.
