Fiber optic strain sensor (high spatial resolution type)
【Features】 ● Continuous distribution measurement of strain is possible with a pitch of less than 1mm !! (Values equivalent to hundreds of 1mm strain gauges can be derived from a single fiber) ● Excellent water resistance, explosion-proof properties, and heat resistance, allowing for long-term absolute strain measurement (without drift)

Company information
Generally, when we think of optical fibers, we recall optical communication, but optical fibers, represented by optical waveguides (the paths through which light travels), can also serve as sensors. Optical fiber sensors are gaining attention as next-generation measurement devices. To realize a safe and secure society, it is crucial to ensure that civil structures supporting the foundation of society and production facilities generating economic benefits remain in a sound state against challenges such as natural disasters like earthquakes and aging. Sensing technology can be likened to the sensory nerves of the human body. By leveraging the unique advantages of optical fibers, such as explosion resistance, durability, electromagnetic resistance, and heat resistance, we aim to realize a safe society as the sensory nerves of society; this is our goal. At times, safety and security are described as "out of sight, out of mind." However, in places that do not attract public attention, diligent operational management, safety management, and maintenance work are carried out day and night with significant manpower and time. Enhancing and complementing this precious and costly environment of "safety and security" with light is our collective goal and the philosophy of "sweat and high-tech."
