Abstract
An interferometer having a tunable optical resonator using a monomode optical fiber as the light propagation medium. According to a preferred embodiment the fiber (1) is wound around a cylindrical mandrel (7) made from a piezoelectric ceramic material. Multiple reflections are ensured by reflecting deposits at the fiber ends. Rapid scanning of several orders of interference can be obtained by applying an alternating voltage V to the ceramic material.
