Fiber Bragg Grating (FBG) sensing technology is a new type of sensing technology that has developed over the past decade internationally. It uses optical fibers both for signal sensing and transmission, representing the most outstanding example of fiber-based sensing technologies. Currently, this technology has become relatively mature and has been successfully applied in multiple related industries. FBG sensors can measure various physical quantities such as pressure, acceleration, displacement, water level, etc., and can achieve distributed multi-point measurements along a single fiber.
The FBG sensing system employs high-power wavelength-scanning lasers. Its modular design makes it more convenient for users to select appropriate products based on actual engineering needs. The scanning speed can reach up to 250Hz, suitable for real-time analysis. This system is not only suitable for practical engineering applications but also for laboratory use, and can be customized according to user requirements.
