摘要： An optical sensor (600) for detecting the movement of an object relative to the position of the optical sensor (600), using self-mixing interference, is described. The optical sensor (600) comprises a laser (100), a detector (200) and a filter device (500). The filter device (500) suppresses measurement signals generated by means of the detector (200) when movements of the object at a velocity below a defined threshold value cause the measurement signals. The optical sensor (600) may be used in a switch in order to enable selective switching depending on the velocity of the movement of the object.

摘要： An apparatus, method and computer program for measuring a distance using a self-mixing interference (SMI) unit that generates an SMI signal. The SMI unit comprises a laser emitting a first laser beam directed to an object and wherein the SMI signal depends on an interference of the first laser beam and a second laser beam reflected by the object. A peak width determination unit determines a peak width of the SMI signal, and a distance determination unit 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： The method is based on a determination of the orientation of the sensor to the surface moving with respect to the sensor and then acquiring data where the lateral velocity is small and the forward velocity is large. Then, the orientation of the sensor with respect to the direction of the forward velocity is determined and the velocity data subsequently measured are corrected using the measured orientation of the sensor with respect to the reference surface and the forward velocity direction.

摘要： The invention relates to a velocity determination apparatus for determining a relative velocity between a first object (12), to which the velocity determination apparatus is attachable, and a second object (1). The velocity determination apparatus comprises a laser (3) having a laser cavity (4) for emitting first radiation (5), which is reflected by the second object (1), wherein the reflected radiation interferes with the first radiation (5) within the laser cavity (4). An interference signal detector (7) detects an interference signal depending on the interference within the laser cavity (4) and a velocity determination unit (8) determines the relative velocity based on the interference signal. A reliability value determination unit (9) determines a reliability value for indicating the reliability of the determined relative velocity based on at least one of the group consisting of the detected interference signal, the determined relative velocity and a characteristic of the laser.

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.
