ABSTRACT:
An optical transducer for converting pressure variations to variations in amplitude of an optical signal. A first optical transmission line is positioned above a base in a manner to maintain its end face stationary while a second optical transmission line is positioned above the base in a manner to permit the axis to be displaced from the axis of the optical fiber with the stationary end face in accordance with variations of pressure applied thereto. Optical signals propagating in one of the optical transmission lines will couple to the other with a coupling factor dependent upon the axial displacement of the optical fibers. Under conditions of continuous pressure variations, such as that created by an incident acoustic wave, the coupled optical signal will be amplitude modulated in accordance with the pressure variations.
