Fiber Bragg Grating

Caption

Fiber Bragg gratings are used to turn an optical fiber into a sensing element by reflecting a specific wavelength back in the direction from which it came. New dissolvable fiber Bragg gratings can be used as sensors in the body and are safe even if the fiber were to accidently break inside the patient.
