Do fiber optic sensors have directionality

The directionality, or directional sensitivity, of a fiber sensor to a sound wave depends on the sound frequency and wave-length, and on the geometric structure of the sensor. A fiber-optic sensor is a sensor that uses optical fiber 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 remote sensing. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. This article will explore the principles behind fiber optic current sensors.
