摘　　要：激光束透过纸张后体散射场的场强大小和分布与纸张的厚度、白度和均匀度有着密切关系。体散射场分布能够直接反映纸张的质量情况,是检测纸张质量的理想参考标准。在蒙特卡罗测试法的基础上,提出一种简单实用的纸张质量检测技术。利用He-Ne激光器发出的激光束透过纸张后测量其体散射场,通过实验计算得到的模拟曲线能够很好地描述纸张的光学质量,与理论计算的体散射场曲线有很高的吻合度。The scattered field intensity and distribution produced by the laser beam through the paper are relevant to thickness,whiteness and uniformity.The scattered field distribution can directly reflect the quality and is a reference standard of testing it.In the Monte Carlo test method is proposed based on a simple and practical paperquality testing techniques.The scattered field is measured by He-Ne laser through the paper,and the analog curve from the test calculation can describe the paper′s optical quality.The result fit well with the theory curve of the scattered field.
