逆反射光场光能分布

The Energy Distribution in Retroreflecting Light Field

用统计光学的理论对逆反射光场的能量分布规律进行了研究，推导出光场能量的分布呈高斯分布，并借助于计算机仿真的方法找出了高斯分布参数σ与发散角、工作距离之间的关系。最后，采用ＣＣＤ图象传感器扫描测量了逆反射光场，对实测数据进行随机样本分析。

The rule of energy distribution in retroreflecting light field was studied by means of the theory of statistical optics in the paper.The energy distribution in retroreflecting light field presenting Gaussian distribution is derived.The relationship of Guassian distribution parameter σ ,divergence angle and operating distance was discovered through computer simulation.Finally the retroreflecting light field was scanned by CCD image sensor and the practical measured data were analyzed with random sampling method.The correctness of the theoretical analysis was proved in experiments.
