Abstract
A device for measuring the distances (d) to far-off objects () and close objects by emitting modulated laser beams () that are reflected on the objects. The device includes an objective (), structure(s) () for selecting beams, and a receiver (). Beams are bundled by the objective, the beams not only containing the laser beams () reflected on the objects but also background beams (). The beams in an associated cross-sectional region () of the bundle are selected from a bundle of beams by the selection structure(s) (). The cross-sectional region includes a first section () and at least one second section (), laser beams () reflected by a far-off object being associated with the first section (), and laser beams () reflected by a close object () being associated with the at least second section ().
