Fiber Bragg Grating Temperature Compensation - FBG Stress and Strain Displacement Sensor - Technical Solution of Temperature Compensation Principle
This page provides a dedicated introduction to temperature compensation for fiber Bragg grating (FBG) sensors, focusing on the following aspects:
1. Principles of Temperature Compensation for Fiber Bragg Grating Sensors
Considering the principles of FBG and the sensing formulas of FBG, it is known that FBGs are sensitive to both stress and temperature (ultimately reflected as strain changes, i.e., length changes). When various physical quantities are measured using FBG sensors, they are often affected by changes in the environmental temperature. Therefore, in order to achieve accurate measurements of stress, strain, shape, angle, and vibration, temperature compensation for FBG sensors is essential.
2. Accurate Testing of Fiber Bragg Grating Temperature Sensors as a Prerequisite for Temperature Compensation
From the principles of FBG and the temperature compensation for FBG sensors, the premise for performing temperature compensation on various FBG sensors is to have a highly accurate FBG temperature sensor. DCYS provides a series of OFSCN® capillary seamless steel tube FBG temperature sensors that offer precise temperature measurements.
3. Temperature Compensation Principles and Schemes for Various OFSCN Fiber Bragg Grating Sensors
This includes temperature compensation for FBG stress sensors, FBG strain sensors, FBG shape sensors, FBG angle sensors, and FBG vibration sensors.
