Abstract
The invention consists of a method of redirecting light to improve the transmission efficiency of wedged multibeam interferometers, either individually or in cascade with other interferometers. Optical fibers are placed to direct reflected light into such positions which enable iterated transmission of this otherwise wasted light through the interferometer. The increased light coupling efficiency provided by the method makes it well suited for applications to fiber optic communication links, fiber optic Bragg sensors, ladars and lidars.
