Where is the Huijue R 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 Context

The 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 .

Applications

Huijue 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 .
