摘要：A device for measuring movement of an object (15) and the device relative toeach other. The device comprises a laser (3) for generating a measuring beam (13), whichis converged by a lens (10) in an action plane. Radiation reflected by the object (15) isconverged to re-enter the laser cavity to generate a self-mixing effect in the laser (3).Measuring means (4) are provided to receive the reflected measuring beam radiation andenable the frequency difference between the measuring beam (13) and the reflectedmeasuring beam radiation to be determined, which is representative of the relativemovement.
