| 摘 要： | 为了研究声光Naman-Nath衍射的光强度分布情况;利用CCD结合数字图像技术分析了衍射光谱的强度分布;根据强度分析得到各级衍射谱线的相对强度,与理论数值计算对比,得到超声场引起的相位延迟υ=1.37,相应的声致折射率变化量Δn=3.45×10-6;表明用CCD观察拍摄Naman-Nath衍射光谱并结合图像的强度分析,不仅能得到各级衍射光的相对强度,与理论数值计算比较后,可进一步得到声光相位延迟和声致折射率变化.

| Abstract: | For study of the intensity distribution of the Naman-Nath diffraction,the intensity distribution of the diffraction spectrum was analyzed base on CCD image disposal.The comparative intensity was obtained base on the intensity analyses,and the phase delay and the refractive index increment by the acoustic-optic effect were obtained.Those were compared with theoretic numerical calculation.The results show： The CCD image technology is useful to screen the diffraction spectrum;The image analysis not only obtains the comparative intensity,but also obtains the phase delay and the refractive index increment compared with theoretic numerical calculation.. |
