Three-dimensional Reconstruction of Strain Field and Temperature Field

Three-dimensional (3D) reconstruction of strain field and temperature field based on distributed fiber-optic sensing technology use optical fibers as sensors to measure physical quantities, such as strain and temperature, along the entire length of the fiber. This technology is particularly useful for monitoring and analyzing structural behavior and integrity in various applications, including civil engineering, geotechnical monitoring, and industrial processes. Distributed fiber-optic sensors offer several advantages over traditional point-based sensors, including continuous and high-resolution measurements, immunity to electromagnetic interference, and the ability to sense over long distances.

The temperature and strain field reconstruction software is based on the principle of color intensity mapping, and it is divided into modules including data reception, data processing, intensity color mapping, interpolation mapping, display, and save/playback data. Each module performs its respective function and is coordinated and controlled by the main program. The sensor data is collected, processed, and displayed in real-time as a cloud map, achieving the visualization of collected data. The three-dimensional reconstruction software supports five types of fiber optic sensor layouts, namely: straight line, arc, spiral, circle, and cylinder.

Composite Materials Fatigue Detection

Composite materials, characterized by their lightweight, high strength, and ease of molding, have found extensive applications in sectors such as aviation, automotive, and wind power. Lightweighting is a prevailing trend in the composite materials industry. Ensuring quality and performance while achieving greater lightness presents a new challenge. Whether in the production process control of high-quality composites or in monitoring the operational state of finished products, fiber optic sensing technology, as a non-destructive measurement method, is highly suitable for testing and monitoring.

Fiber optics, as a new type of sensor, has advantages such as being lightweight, flexible, and resistant to electromagnetic interference. Its small size allows it to be embedded within materials without compromising strength performance, making it an ideal choice for testing various parameters of composite materials. When used for material inspection, it exhibits high accuracy and tracking measurements. Through failure analysis, it helps identify potential reasons for the failure of composite materials in design, production, processes, and usage stages. This in-depth examination of the failure mechanism provides a theoretical basis for improving product yield and optimizing processes.
