Abstract

A fiber-optic interferometer is disclosed in the figure. A bifurcated optical fiber bundle has a first leg A and a second leg B joined at a second end 2 which is capped with a partially silvered mirror 3 and mechanically anchored to a reference point 4. A reflective surface 5, whose position or motion is to be measured, is located in proximity at a distance delta from the partially silvered mirror 3.
