Large deformation polymer optical fiber sensors for civil infrastructure systems

Studies on development of NiTi-integrated optical fiber sensor and its life cycle behavior

“…The POF (1 mm diameter, 0.5 mm core diameter, and 200 mm length) was mounted in an in situ rotatable fixture as shown in Figure 2, which will assist to obtain the uniform deposition of the entire circumference of the fiber. The optical fiber samples are pre-strained 5% using mechanical loading (Abdi et al, 2008). The POF consists of core and cladding structure construction and its properties are shown in Table 2 (Huang et al, 2015).…”

Detecting Supercritical CO2in Brine at Sequestration Pressure with an Optical Fiber Sensor

“…Sensors based on optical fibers have several inherent advantages including immunity to electromagnetic interferences, compact size, high sensitivity, robustness, low signal loss and capacity for distributed in situ sensing over large distances. , Leveraging these advantages, optical fiber sensors have been successfully used to measure parameters such as temperature, pressure, pH and chemical composition . Applications include aerospace instruments, biomedical devices, , chemical detection devices, structural health monitoring, and energy and environmental processes. , In the context of subsurface energy and environmental processes, there is precedent for optical fiber based sensing of pressure, temperature, vibration and flow rate. , …”
