0427951Anbo WangVirginia TechSensors for civil infrastructure monitoring require capability of dense multiplexing, long span or large area coverage, minimum maintenance, low cost, versatility response to a range of key measurands, and harsh environment performance. The objective of this project is to develop a new optical fiber sensor technology that would increase the multiplexing capability and permit measurement of a number of key structural health and integrity parameters, such as pressure, strain and temperature. This work is directly based on a newly demonstrated UV-induced intrinsic Fabry-Perot interferometric (IFPI) fiber sensor method at Virginia Tech's Center for Photonics Technology. Sensor performance characteristics will be optimized by developing a thorough understanding of the effect of sensor fabrication and multiplexing parameters through both mathematical modeling and experimental analysis. Different types of data aggregation will be investigated for real-time infrastructure monitoring by a large number of heterogeneous sensors using a hybrid of hierarchical and data-centric approaches. . A multidisciplinary team has been assembled to accomplish these objectives leveraging expertise from the mathematics, electrical engineering, materials science and computer engineering at Virginia Tech.Through novel sensor design and computer networking, the successful completion of the research will result in a revolutionary increase in sensor multiplexing density for large area coverage of physical parameter measurements with high spatial resolution and harsh environment capability. Such capabilities will permit real time monitoring of critical civil and industrial infrastructure both for future economic growth, and homeland security at a scale previously unrealizable. This is an integrated research group (IRG) proposal supported by Division of Civil & Mechanical Systems (CMS) under Sensors Initiative NSF04-522.

用于民用基础设施监测的传感器需要具有密集复用、长跨度或大面积覆盖、最低维护、低成本、对一系列关键被测对象的多功能响应以及恶劣环境性能的能力。 该项目的目标是开发一种新的光纤传感器技术，该技术将增加多路复用能力，并允许测量一些关键的结构健康和完整性参数，如压力，应变和温度。 这项工作直接基于弗吉尼亚理工大学光子技术中心新展示的紫外线诱导本征法布里-珀罗干涉（IFPI）光纤传感器方法。 传感器的性能特性将通过开发一个透彻的理解传感器的制造和复用参数的影响，通过数学建模和实验分析进行优化。 将研究不同类型的数据聚合，用于大量异构传感器使用分层和以数据为中心的方法的混合进行实时基础设施监控。 .一个多学科的团队已经组装，以实现这些目标，利用专业知识，从数学，电气工程，材料科学和计算机工程在弗吉尼亚理工大学通过新颖的传感器设计和计算机网络，该研究的成功完成将导致传感器复用密度的革命性增加，以实现大面积覆盖的物理参数测量，具有高空间分辨率和恶劣环境能力。 这种能力将允许对关键的民用和工业基础设施进行真实的实时监测，以实现未来的经济增长和国土安全。 这是一个综合研究小组（IRG）的建议，由土木机械系统（CMS）部门根据传感器倡议NSF 04 -522支持。
