<p>The scanner (10) has a semiconductor light source (12) provided for transmission of light rays (16). Rotary mirrors (20) are provided for periodic deflection of the rays in a deflection direction. A light receiver (38) i.e. photo diode, produces receiving signals from light rays (32) that are reflected in a monitoring area. A diverting mirror (42) diverts the reflected light rays to an oscillation mirror (44), which is designed for periodic deflection of the light rays (16, 32) in another deflection direction that is transverse to the former deflection direction.</p> |
