Where is the Huijue fiber optic sensor located

The Huijue R fiber optic sensor has been deployed at Huijue's Shanghai testbed for experimental and monitoring purposes.The Huijue R fiber optic sensor is part of Huijue's advanced fiber optic sensing systems, which utilize technologies such as distributed acoustic sensing (DAS), Brillouin optical time-domain analysis (BOTDA), and optical frequency domain reflectometry (OFDR) to monitor structural and environmental changes with high precision . According to available reports, these sensors have been trialed at Huijue's Shanghai testbed, where they measure microstructural variations, temperature, and strain with sub-meter resolution and high accuracy .Technical ContextThe sensor operates by detecting variations in photon lifetime and optical signal characteristics along the fiber, allowing it to sense strain, temperature, and other physical parameters remotely . It is embedded within optical fibers, which can be installed in infrastructure such as tunnels, pipelines, or other civil engineering projects. The system is designed for high-resolution monitoring and can integrate with digital twins and edge computing nodes for real-time data analysis .ApplicationsHuijue R fiber optic sensors are used for:Infrastructure monitoring (e.g., subway tunnels, pipelines)Environmental sensing (temperature and strain detection)Research and development in photonics-based sensing technologies While the exact street-level location of the sensor is not publicly disclosed, the Shanghai testbed serves as the primary deployment site for Huijue's experimental trials and demonstrations . This testbed allows researchers to validate sensor performance under controlled yet realistic conditions. In summary, the Huijue R fiber optic sensor is located at Huijue's Shanghai testbed, where it is used for high-precision monitoring and testing of fiber optic sensing technologies in infrastructure and environmental applications .
