Abstract

A novel low-coherence interferometer (LCI) using a self-mixing superluminescent diode is described. The optical scheme proposed uses the photodiode on the back-face of a commercial super luminescent diode to detect the interference signal from a Fizeau interferometer. Interesting characteristics are low cost and small size, high stability and resolution. The proposed interferometer is expected to have several industrial as well as medical applications.
