Abstract
A low coherence speckle interferometer implemented using single mode optical fibre 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 ofthe system are discussed.
