光纤传感导论
OFS is a leading manufacturer of 光纤s 和 cables for dem和ing 传感 applications.
Fiber optic sensors detect changes in temperature, 应变, 和 other parameters by using the physical properties of light as it travels down an 光纤. 在很多情况下, 光纤本身就是传感器, resulting in thous和s of continuous sensor points along the fiber length. This is an ideal way for measuring many different types of conditions 和 small changes accurately.
光纤传感应用
The fundamental characteristics of 光纤 和 cable, 帮助自己解决现实世界的问题.
- Imagine being able to monitor the entire length of a water, 石油, 或者燃气管道来创建温度曲线, 确保足够的流量.
- How about listening to that same pipeline to detect small, manageable leaks at any point along the pipe – before they become catastrophic?
- What if we could sense seismic activity over great areas, using existing telecommunications cables?
- 有可能检测到人流量吗, 车辆运动, 或者是远程边界的入侵活动?
- Could we reduce the frequency 和 severity of train derailments by working to detect rail fatigue or break 和 their causes – preventing, 而不是事后回应?
- Why not use a “smart fiber” that is minimally intrusive, 几乎没有重量的, to monitor the dynamic 3D shape of a structure to which it conforms?
光纤传感技术
- 分布式温度传感(DTS)DTS measures the temperature profile along the fiber length that extends from the source to the detector by measuring light attenuation induced by temperature changes. Several research groups have well-characterized the attenuation vs. temperature curve for silica glass over a wide range of temperatures, making it a convenient way to measure temperature profiles inside pipes or other structures.
- Electricity – Distributed Temperature Sensing (Electrical DTS) – Reliable temperature measurement of high-voltage transmission lines is critical to help secure the rising dem和 for electricity. 来自OFS的先进光纤，集成在 分布式温度传感器 on power lines, help ensure optimal safety 和 performance in both medium- 和 long-distance systems.
- Oil 和 Gas Distributed Temperature Sensing (Oil 和 Gas DTS) – Many l和 和 subsea 石油 operations rely heavily on 分布式温度传感 for improved safety 和 functionality in these harsh environments. OFS 光纤s help ensure reliable performance 和 durability in high-temperature, 高压, 以及富氢环境.
- 分布式声学传感(DAS) -分布式声传感 utilizes 光纤 to detect acoustic vibration. Sound is detected as if microphones are placed at meter intervals along spans reaching more than 100 km. AcoustiSens® Wideb和 Vibration Sensor Fibers 和 Cables are vibration 传感 fibers 和 cables optimized for 分布式声学传感(DAS)系统. 采用基于ITU-T - G的波导设计.657.A1电信级单模标准, AcoustiSens Wideb和 光纤s significantly increase Rayleigh backscatter while maintaining low attenuation to improve Optical Signal to Noise Ratio (OSNR).
- 石油和天然气-分布式声学传感(DAS) – 光纤接入 油气DAS applications allow for near real-time measurements. 低衰减, 长时间接触, 和介电性质(不受射频干扰和电磁干扰), 光纤 in DAS creates a long sensor element (up to 50 km) that can detect high-resolution events throughout the entire length of the fiber. Our Ge-doped single-mode 和 pure-core single-mode fiber type products, 特别是, 提供每个传感器点的低成本.
- 分布式应变传感(DSS) -应变传感, fiber optic cables are engineered 和 mechanically coupled to structures like dams 和 pipelines where ground movement can be detected 和 threatened locations pinpointed.
- Distributed Strain 和 Temperature Sensing (DSTS, also called DTSS) – DSTS is used where critical systems of great length can be continuously monitored for temperature 和 应变 to ensure fault-free operation while improving safety.
- 光纤导航传感 – Fiber optics are used in navigation systems to provide accurate information about location 和 direction. Aircrafts, missiles, unmanned aerial vehicles (UAVs), 和 ground vehicles all require advanced 光纤导航技术 确保可靠性和安全性.
- 形状传感技术 – 形状传感 allows a fiber to be embedded or attached to a surface to monitor dynamic 3D shapes 和 enable successful minimally invasive surgery, 医疗器械指南, 风能和燃气轮机叶片监测, 石油钻探勘探, 以及海底防御行动.
