  • Apparatus for generating a light curtain
    Patent number: 5080457
    Abstract: An apparatus is described for generating a light curtain which includes an originally spherical strip-like concave mirror 10 and a light deflecting element 12 arranged in the vicinity of the focal point of the concave mirror. The light deflecting element 12 guides a bundled light beam periodically over the concave mirror 10. The strip-like concave mirror 10 is twisted within itself in such a way that each surface portion of the concave mirror 10 which is illuminated during a complete sweep of the light beam extends at at least substantially the same angle to the beam axis in a plane perpendicular to the scanning direction.
