摘要：

In order to improve the response time of fiber optical temperature sensors, a fast response temperature sensor based on the Venturi structure is proposed. This sensor takes advantage of the Venturi structure to increase fluid flow velocity, thereby increasing thermal conductivity and reducing the temperature response time. Simulation analysis of the Venturi temperature sensor based on fiber Bragg grating (VFBGT) showed that it has a shorter response time compared to a bare FBG at different flow velocities. The structure of the VFBGT was optimized to achieve the minimum response time. Experimental results confirmed that the VFBGT can reduce the temperature response time of the bare FBG sensor from 420ms to 210ms at a flow velocity of 1m/s, providing a new approach for dynamic temperature measurement and real-time fast temperature compensation in high-precision systems.
