拉盖尔-高斯光束照射产生散斑场的特性研究 = Study on properties of speckle field formed by Laguerre-Gaussian beam illumination
研究了拉盖尔-高斯光束照射毛玻璃产生的散斑场的特性。利用空间光调制器结合计算全息法产生了拉盖尔-高斯涡旋光束；较深入地研究了拉盖尔-高斯光束照射下散斑大小与光束径向指数、角向指数及涡旋光束面积间的关系。结果显示：对同一径向指数，散斑颗粒平均大小随角向指数的增大呈直线减小趋势；对同一角向指数，散斑大小随径向指数的增大而减小；散斑大小与涡旋光束照射面积的负指数成正比；随径向指数的增大，其逐渐接近高斯光束照射的结果。 The properties of speckle field is studied when Laguerre-Gaussian (LG) beams illuminate a gr...
