    摘要: The invention relates to a method for measuring a velocity of an object surface (O) relative to a sensor (1) with at least one light-sensitive element (2) according to the spatial frequency filtering method, wherein the light-sensitive element (2) is read at time intervals, and wherein the spatial frequency filter is designed as at least one masking grating having a variable grating constant. The method according to the invention is characterized in that the relative velocity is first measured using a first grating constant k1 having a large period length and/or over a short observation time period t1 (rough measurement) and then the measurement of the relative velocity is repeated for a more exact determination using a second grating constant k2 having a small period length and/or over a long observation time period t2 (fine measurement). The invention further relates to a sensor for velocity measurement.

    摘要: The invention relates to a system for determining the speed of a motor vehicle. In order to provide a sufficiently accurate system for determining the speed of a landcraft, in a first step according to the invention, a heat generating source that is arranged on or in the motor vehicle partially heats at least one point of the roadway on which the vehicle travels, and a speed determining device records the time of calefaction. In a second step, a heat sensor located on or in the vehicle senses that the roadway has been partially heated. The speed determining device records or registers the time of sensing by the sensor. According to the invention, the speed determining device knows the predetermined distance between the heat generating source or the point where the roadway is partially heated and the heat sensor. The speed determining device calculates the vehicle speed, especially the forward speed and/or the transversal speed of the vehicle, from the predetermined distance and the difference between the time the heating process occurs and the time the sensor senses the calefaction.
