Claim Text:
1. An interferometer comprising: an optical element; a frame; a bendable membrane that couples the optical element to the frame, the bendable membrane extending from an outer circumference of the optical element to the frame; at least one piezoelectric actuator that is substantially mounted on said bendable membrane between the frame and the optical element, the at least one piezoelectric actuator being adapted to contract in a radial direction and bend the bendable membrane to provide a movement to the optical element subject to signal from a signal generator; an at least partially reflective surface disposed on the optical element; a housing comprising: wherein the frame is mounted in the housing; and wherein the at least partially reflective surface and the second reflective surface are positioned at a distance from each other constituting a Fabry-Perot element, the distance being adjusted by the movements induced by said at least one piezoelectric actuator.
