摘要： A method for controlling an opto-electronic measuring device for radiation based object point measuring such as a laser tracker, laser scanner, multi beam scanner, laser profiler, scanning total station, flash lidar, airborne scanning lidar or scanning multi station. The power of the emitted measurement radiation is object individually automatically varied specific for a direction and distance to respective objects whereby the power is adjusted in such a way that it does not exceed a predefined distance dependent power limit applying to the respective object distance precisely when the measurement radiation is emitted in the respective object direction.

摘要： A distance meter for the high-accuracy single-point distance measurement to a target point by means of an oriented emitted beam, wherein the receiver has an optoelectronic sensor based on an arrangement of microcells for acquiring the received beam. The receiver and a computer unit are configured in this case for deriving a set of runtimes with respect to different cross-sectional components of the received beam acquired using subregions of the receiver, and therefore, for example, an evaluation is enabled as to whether the received beam has parts of the emitted beam reflected on a single target or a multiple target in its lateral extension.

摘要： A distance measuring method and an electronic laser distance measuring module, for determining a distance to a target object, wherein the transmitted signal is emitted with selected polarization states by a transmitting unit of the laser distance measuring module. The transmitted signal is emitted and the received signal is acquired such that a polarization identifier of the polarization state of the transmitted signal adheres to the received signal and an evaluation of the received signal is derived based on the polarization identifier, to take into consideration multiple reflections during the processing of the received signal to determine the distance.
