摘要
本文提出了采用对金属丝网光学傅里叶频域中谱点光强锐度分布进行概率统计分析,以实现金属丝网超大网孔尺寸与超差比例检测的检测方法,并进行了实验研究。实验结果表明,采用概率统计分析实现金属丝网超差尺寸检测的检测方法是较为有效的。
In this paper, the method, which is applied to measuring the sizes exceeding the specified sizes of wire sieves by using probable statistic analysis for the acutance of the intensity spectrum, is proposed. It is verified through the experiments. The experimental results show that the method is applicable.
