Abstract (en)
[origin: CA2985403A1] The invention relates to a device for optically measuring the distance from a reflective target object, comprising a beam source, a detector, a beam-shaping system having an optical transmission system and an optical receiving system, and a laser beam-shaping element (62) which can be arranged in the optical path of the laser beam (51). Said laser beam-shaping element (62) is in the form of a transmission aperture arrangement that has at least one transmission aperture (63), said at least one transmission aperture (63) generating a sub-beam (64) and expanding this sub-beam (64) to one or more opening angles (a1) no smaller than a minimum critical angle of 1.0 mrad.
