Abstract
In a method for scanning distance and velocity determination of at least one object, a light source emits an optical signal with a time-varying frequency. A first difference frequency distribution is determined that represents, for different pixels on the at least one object, a difference frequency between a measurement signal originating from the optical signal and reflected at the respective pixel and a reference signal not reflected at the object. At a later time, a second difference frequency distribution is determined. Then the first and the second difference frequency distributions are aligned by performing a transformation of the pixels of the first and of the second difference frequency distributions in such a way that after this alignment, pixels corresponding to each other both distributions correspond to the same object point. Finally, the distance and velocity for each pixel is determined using the two aligned difference frequency distributions.
