Abstract
The dislocation sensor based on the contrast phenomenon in an unbalanced fiber optic Michelson interferometer with a 3 x 3 coupler and a semiconductor multimode laser. Periodic contrast oscillations, which depend on a laser spectrum, occur if a measuring arm of the interferometer is elongated. A conception of the elongation sensor that based on linearization of contrast oscillations is shown. Next, a setup of the sensor and signal processing scheme of the sensor is presented. During measurements, for 1-m long sensor we obtained 5-mm measuring range with ±28-μm uncertainty. Explanation of these differences and conclusion to further research are formulated.
