  • Apparatus for Optically Measuring the Distance to a Target Object
    Publication number: 20220342042
    Abstract: An apparatus for optically measuring a distance to a target object which is embodied as a scattering target object or a reflecting target object. The apparatus has a distance measuring device and an adjustment device. In the distance measuring device, a laser beam is generated which is adjusted with the aid of the adjustment device to an external optical unit. The adjustment device includes a beam shaping optical unit and a focal shift device.
