Linear displacement sensor os1100

non-contactfiber opticwith fiber Bragg grating

The os1100 Fiber Bragg Grating (FBG) is designed for use in fiber optic sensing applications. It is a single FBG centered in a two meter length of polyimide coated optical fiber. It may be used individually or can be spliced into an array of many FBGs. Fiber Bragg gratings are the fundamental elements upon which most fiber optic sensors are based. An FBG is an invisible reflector inside the core of the fiber that is set to a specific wavelength of light. When the fiber where the FBG is located is exposed to strain or temperature, the FBGs center wavelength shifts to a higher or lower wavelength. The direction and magnitude of the shift is proportional to the change in strain or temperature. os1100s are available in dozens of distinct center wavelengths. Using different wavelengths allows multiplexing of dozens of FBGs on a single fiber.
