基于光电检测技术棉花成熟度快速评估方法的研究
A Novel Method to Assess Cotton Fiber Fineness and Maturity Based on Optoelectronic Measurement
摘要
棉纤维成熟度及细度参量是影响纺织加工质量的一个重要指标，目前采用的间接测量方法不能准确评价棉纤维的品质质量.本文利用夫琅和费衍射光学方法，线阵CCD探测棉纤维衍射光信号，经小波分析去噪，根据明暗条纹分布计算获得待测棉纤维细度.在实验室恒温（23℃）、恒湿（45%）环境下，对8个品种不同成熟度等级的棉花进行了测量，同显微镜测量结果相比较，结果表明两种方法有很好的相关性，相关系数为0.956，均方差为0.332.因此基于光电检测技术方法能够实现实验室中棉纤维成熟度快速检测，为实际生产中棉花成熟度直接、快速的光电检测提供了理论研究基础.
Abstract
The cotton′s maturity and fineness are the key parameters to evaluate the cotton fibers quality. The indirect parameters measurement can not accurately evaluate the cotton fiber′s quality. A direct method based on the optoelectronic measurement of Fraunhofer diffraction was presented. The measurement results were compared between the microscope and the optoelectronic setup. The results show that two methods have the good correlation(R=0.956, and SD=0.332). The optoelectronic technique can assess the cotton fiber′s maturity in the lab.
