摘要： The invention relates to a velocity determination apparatus (1) for determining a velocity of an object (2). A Doppler frequency measuring unit is adapted to measure Doppler frequencies in at least three different frequency directions, wherein a Doppler frequency calculation unit is adapted to calculate a Doppler frequency for a calculation frequency direction being similar to one of the at least three different frequency directions depending on the Doppler frequencies measured for at least two further frequency directions of the at least three different frequency directions. The velocity can then be determined depending on the calculated Doppler frequency and the measured Doppler frequencies. Since in the calculation frequency direction the measured Doppler frequency is not needed for determining the velocity, a reliable velocity can be determined also in the calculation frequency direction, even if the measurement of the Doppler frequency in this calculation frequency direction is disturbed.

摘要： The invention relates to an apparatus for measuring a distance. A self-mixing interference (SMI) unit (2) generates an SMI signal, wherein the SMI unit comprises a laser (3) emitting a first laser beam (4) for being directed to an object (5) and wherein the SMI signal depends on an interference of the first laser beam and a second laser beam (6) reflected by the object. A peak width determination unit (8) determines a peak width of the SMI signal, and a distance determination unit (9) determines a distance between the object and the SMI unit depending on the determined peak width of the SMI signal. Since the distance is determined depending on the peak width of the SMI signal, without requiring a laser driving current modulation, advanced electronics for modulating the driving current of the laser are not needed. This reduces the technical efforts needed for determining the distance.

摘要： A sensor system is described, using self-mixing laser sensors (10) and an analyzer circuit (30) in order to determine the velocity of a vehicle, such as a car, and the rotational velocity of a wheel (20) of the car. Deviations between the velocity of the vehicle and the rotational velocity of the wheel (20) can be used to determine sliding of the wheel (20) and, finally, the traction or, more specifically, the coefficient of driving friction between the wheel (20) and the surface the car is driving on.

The test accelerations initiate short periods of sliding of the wheel (20) and the sliding is detected by means of the sensor system.

摘要： The present invention refers to a method of operating a self-mixing interference sensor and a corresponding self-mixing interference sensor device. In the method the laser (1) of the device is controlled to periodically emit a laser pulse followed by an emission period of laser radiation having a lower amplitude. The pulse width of the laser pulse is selected such that the pulse after reflection at the object (3) re-enters the laser (1) during the emission period of laser radiation with lower amplitude. The corresponding SMI signal has an increased signal to noise ratio.
