Apparatus for ascertaining a velocity component of an object

Abstract

The invention relates to an apparatus for ascertaining a velocity component of an object that moves relative to the apparatus in a detection region at a measurement distance and that reflects light originating from a light source, the object generating reflected light that emanates from the detection region. To this end, the apparatus comprises an objective, a modulator, a reception optical unit and a light detector, wherein the objective detects the reflected light generated by the object in the detection region and elimages said light on the modulator, wherein the modulator modulates the reflected light into a sequence of light signals, wherein the reception optical unit images the sequence of light signals generated by the modulator on the light detector and wherein the light detector converts the sequence of light signals into a sequence of electronic signals. Further, the apparatus comprises an interface which transmits the sequence of electronic signals generated by the light detector to an evaluation unit.
