Apparatus for creating an image indicating distances to objects in a scene. The invention is comprised of a radiation source and modulator, telecentric optics for receiving and collimating the radiation reflected from the scene, a detector and a processor. The detector receives the collimated, reflected radiation and sends a signal to the processor. The processor forms an image having an intensity value distribution indicative of the distance of objects form the apparatus.
