Paper Abstract

A low coherence speckle interferometer implemented using single mode optical fiber and a multimode laser diode as a pseudo-low coherence source is described. The design of the interferometer is presented and demonstrated on simple test objects. Signal processing techniques to improve the performance of the system are discussed.
