A distance measurement device which has a lighting unit, including transmission optics with light beam forming optics. Illumination patterns are formed on objects in the measurement area which differ depending on the distances from the measurement device. A light receiving unit is arranged adjacent the lighting unit and generates an image of the illuminated object via receiving optics. A detector array is located in the image plane of the receiving optics which converts the optical image into corresponding electrical signals. The signals from the detector area are forwarded to a signal processing unit that is capable of generating information concerning the distance between the object and the distance measurement device from the detected illumination pattern and the signals generated by the detector.
