Object e.g. person, optical detection device for use in e.g. automated production site, has laser scanner, and tilted mirror arranged in form of interior reflected cover part section of truncated cone in circulation area of beam

摘要

The device has a laser scanner (2) provided with a transmitter device that produces a collimated beam of impulses of electromagnetic radiation. A receiver receives reflected impulses from a monitoring area. The scanner circularly moves the beam around an axis of rotation with a deflection device (16). An evaluation unit determines relative spatial coordinates of objects in the area from angle and transition time of the impulses. A tilted mirror (1) in the form of an interior reflected cover part section of a truncated cone is arranged in a circulation area of the beam.
