Abstract
A device for the optical measurement of a distance from a reflecting or scattering target object is disclosed. The device has a distance measurement device and an adjusting device arranged outside of the distance measurement device having a second transmission optical unit adjustable between a first and second position for forming the laser light into a beam, where in the first position, the second transmission optical unit is arranged in the laser beam, and in the second position, it is arranged outside of the laser beam.
Claims9
An apparatus for optical measurement of a distance from a reflecting or scattering target object, comprising:
- a distance measurement device, wherein the distance measurement device includes:
- a beam source, wherein the beam source is a first electro-optical component and emits a laser beam;
- a detector, wherein the detector is a second electro-optical component and receives a reception beam reflected or scattered at the target object;
- and
- a first beam-shaping system with a first transmission optical unit for shaping the laser beam and a first reception optical unit for shaping the reception beam;
- and
- an adjustment device disposed outside of the distance measurement device with a second transmission optical unit displaceable between a first position and a second position for shaping the laser beam;
- wherein in the first position the second transmission optical unit is disposed in the laser beam;
- wherein in the second position the second transmission optical unit is disposed outside of the laser beam;
- wherein the first transmission optical unit is a collimation optical unit and wherein the second transmission optical unit is a scattering optical unit.
