What sensing method does a fiber optic sensor utilize
A fiber-optic sensor is a that uses either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in. Depending on the application, fiber may be used because of its small size, or because no is needed at the remote location, or because many sensors can be along the length of a fiber by using light wavelength shift for.
