Abstract

Using polymer optical fibre and Moire patterns an angular and displacement sensor is demonstrated. Using two transparent superimposed planar gratings on an optical mirror, Moire fringes are generated. Measuring the period and the number of periods, the relative angle and the displacement are both obtained. With this technique very low angles with very high resolution can be measure. The sensor principle are successfully checked in the laboratory.
