    摘要: A relative movement sensor for measuring movement of an object (15) and the sensor relative to each other, the sensor comprising a plurality of lasers (3,5) for generating respective measuring beams and illuminating the object (15) therewith, and a plurality of respective photodiodes (4,6) for measuring changes in operation of each laser cavity caused by reflected measuring beam radiation re-entering the respective laser cavity and the optical wave in the laser cavity. The plurality of lasers (3,5) are operated in a time-multiplexed manner such that only a subset (i.e. one or more) of the lasers is operated at any one time, the remaining lasers being idle. This reduces peak power dissipation and prevents erroneous interference caused by measuring beam radiation from one laser entering the cavity of another laser.

    摘要: The present invention relates to a method for measuring blood flow in living tissue and a device for performing the method. The device comprises a laser and a photo sensor. The laser is arranged to illuminate (10) the tissue in such a way that a portion of the light beam, scattered by the tissue, re-enters the laser in order to obtain a self-mixing effect. The resulting light, that is registered (11) as an electric signal by the photo sensor, contains a speckle pattern that is depending on blood cell movement in the tissue. A Fourier transform is applied (12) to this signal and an exponential fit is applied (13) to the resulting frequency domain spectrum. Thereby parameters corresponding to the amount of blood cells and the average velocity of these cells may be obtained.
