摘要：<p>The device has a light source (1) directing light-beam bundles (2) to a reflecting surface. A detector (3) is provided for the reception of the bundles reflected by the surface, where the impinging location of the bundles on the detector is a measure for the distance between the surface and the detector. A lens (4) is provided between the source and the surface, where the characteristics of the lens focus the bundles on the detector.</p>
