Fiber Optic FP Temperature Sensor
In this paper, we propose a high-sensitivity fiber-optic temperature sensor based on the UV glue-filled Fabry-Pérot (FP) cavity in the HCF. Optical fiber Fabry-Pérot (FP) interferometer sensors have long been the focus of researchers in sensing applications because of their simple light path, low cost, compact size and convenient manufacturing methods. The sensing cavity is mounted at the front end of an extended alumina tube and is illuminated by a collimated light.

Fiber Optic Sensor Temperature Drift
Explore the impact of temperature drift on Fiber Optic Gyroscopes (FOGs), effective compensation methods, and experimental results. This study proposes an improved multi-scale permutation entropy complete ensemble empirical mode decomposition with adaptive noise (MPE-CEEMDAN) method based on adaptive Kalman filter (AKF) and grey wolf optimizer-least squares support vector machine (GWO-LSSVM). An algorithm is proposed for pro-cessing the sensors' data in the form of weighted sum of temperature values and its. In this study, the effects of pre-annealing LiNbO 3 crystals at 500 °C on multifunctional integrated optical chips (MIOCs) were investigated through interferometric fiber-optic gyroscope (IFOG) system-level tests. The present invention provides a correction for fiber optic gyro drift rate error due to temperature effects based on either the temperature difference between the gyro housing and the sensor spool, or the rate of change of spool temperature.

External Fiber Optic Sensor
Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required.
