Abstract
An apparatus for recognizing objects with a laser light source and a light receiver has an at least partly reflective wall and an interspace between the laser light source and the wall, through which an object can be moved or in which an object can be placed. A movable mirror device is arranged between the laser light source and the wall in such a way that light emitted by the laser light source can be directed onto the wall. In a method for recognizing objects a mirror device directs the light onto an at least partly reflective wall and is controlled in such a way that the wall is irradiated by the light. The light receiver detects the light reflected from the wall and, in the process, registers an object moving or placed between the laser light source and the wall by way of a change in the reflected light detected.
