Abstract

We develop a self-mixing interferometer capable of measuring the position (with half-wavelength resolution) and the two attitude angles - pitch and yaw - (with 15 microrad resolution) of a machine tool turret. The three measurements are performed, for the first time to the best of our knowledge, simultaneously and using a single channel optical signal.
