Highly Sensitive Temperature and High Pressure Sensor Based on a Cascaded Optical Fiber Fabry-Perot Interferometer
A highly sensitive cascaded Fabry–Perot optical fiber sensor for simultaneous measurement of temperature and high pressure is proposed. The sensor comprises a UV glue filled hollow core fiber (HCF) cascaded with an air cavity sealed in a silica capillary tube. The temperature and pressure can be measured simultaneously...
