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. This is a project supported under Sensors Initiative NSF 04-522

摘要0428397 PI：P. PagillaOklahoma State Universe“网”一词用于描述以连续、灵活的带状形式制造和加工的材料。例子包括塑料、纸张、纺织品、金属和复合材料。本计画发展一种新颖的雷射式光纤感测系统，用以监测与控制卷筒纸。该传感技术独特地结合了来自幅材边缘的散射光的多普勒频移、光纤的方向灵敏度特性和准直激光的概念。这种技术集成将导致一个多功能的纸幅传感系统的发展，可以测量纸幅横向位置，横向速度，运输速度，颤振和轮廓。由于感测方案使用来自幅材边缘的散射光，因此该技术同样适用于透明以及不透明的幅材材料，而现有的幅材感测方法并非如此。该研究项目有望推进纸幅处理和传感器技术的科学，并改善纸幅加工线的操作。这是一个由传感器倡议NSF 04-522支持的项目
