SENSORS: A New Laser-Based Sensing System for Monitoring and Control of Webs

PagillaOklahoma州立大学术语卷筒纸用于描述以连续、灵活的带状形式制造和加工的材料。例如塑料、纸张、纺织品、金属和复合材料。本项目开发了一种新型的基于激光的光纤传感系统，用于对卷筒纸进行监测和控制。该传感技术独特地结合了来自纤网边缘的散射光的多普勒频移、光纤的方向敏感性和准直激光的概念。这种技术集成将导致开发一种多功能的网络传感系统，该系统可以测量网络的横向位置、横向速度、传输速度、颤振和轮廓。由于传感方案使用来自纤网边缘的散射光，该技术同样适用于透明和不透明的纤网材料，而现有的纤网传感方法并非如此。这一研究项目有望促进卷筒纸处理和传感器技术的科学化，并改善卷筒纸生产线的运行。这是一个由传感器计划NSF 04-522支持的项目

Abstract0428397PI: P. PagillaOklahoma State UnivThe term web is used to describe materials, which are manufactured and processed in a continuous, flexible strip form. Examples include plastics, paper, textiles, metals, and composites. A novel laser-based fiber optic sensing system for monitoring and control of a web is developed in this project. The sensing technique uniquely combines concepts from Doppler's frequency shift of scattered light from the web edge, directional sensitivity property of the optical fibers, and collimated laser light. This technical integration will lead to the development of a versatile web sensing system that can measure web lateral position, lateral velocity, transport velocity, flutter, and profile. Since the sensing scheme uses the scattered light from the web edge, the technique is equally suitable for use with transparent as well as opaque web materials, which is not the case for existing web sensing methods. This research project is expected to advance the science of web handling and sensor technology, and improve operation of web process lines.
