The osl 200 Fiber Bragg Grating (FBG) Array is designed for use in fiber optic sensing applica- tions. It is a six meter long polyimide coated optical fiber with five FBGs spaced at one meter 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 an FBG is located is exposed to strain or tempera- ture, the FBG's "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. Each osl 200 is built with five FBGs at standard center wavelengths. osl 200 FBG array with optional FC/APC connector os1200's are used in applications ranging from basic experiments with FBGs to construction of complex transducers containing one or more FBGs. The polyimide coating provides excel- lent transfer of strain through the fiber coating to the FBG in the fiber core. Polyimide also performs well over a wide temperature range. The splice free array provides a convenient way to take advantage of the multiplexing capabilities of FBGs. One or two FC/APC connectors, and loose buffer tube protection, are available as packaging
