■Features
・A sensor that uses FBG (Fiber Bragg Grating).
・Detects temperature, strain, and pressure.
・Light speed: Since there is nothing faster than light, the detection speed is extremely fast and does not miss even subtle changes.
- Strong against electricity: It is not affected by surrounding electricity.
- Compact and lightweight: Optical fibers are extremely thin (about 0.1mm), so they can be made smaller.
・Ready to use: Provided ready to use as a sensor. We have accumulated 24 years of optical fiber processing technology into procedure manuals.
■FBG mechanism
FGB is an abbreviation for Fiber Bragg Grating, which is made by irradiating an optical fiber with an ultraviolet laser and creating a refractive index modulation section (bragg This is an optical fiber with multiple evenly spaced gratings (diffraction gratings). When optical fibers expand or contract very slightly due to temperature or strain, the spacing between them changes, and the wavelength changes accordingly.
These slight changes are measured spectroscopically using an Interrogator (optical measuring instrument). For example, in the case of the interrogator that we are currently working on, when the length change is 1pm (picometers, 10^-12M), the temperature change is 0.1℃.
