Abstract: 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.

Abstract: A target object providing a large angular incidence range for retroreflection and a reduced amount of interfering reflections. The target object is configured to provide a 360° all-around retroreflection about a vertical axis and ±45° angular incidence range from the horizontal. According to one aspect, the target object comprises eight triple prisms arranged around the arrangement axis in such a way that their contour embeds in an octahedral shape, wherein four of the eight triple prisms are arranged to embed in a first pyramidal body and other four of the eight triple prisms are arranged to embed in a second pyramidal body. Each of the first and the second pyramidal bodies comprises a pyramid base and four lateral surfaces, wherein the pyramid bases of the first and the second pyramidal bodies are arranged parallel to each other.

Abstract: 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.

Abstract: A distance measuring device comprising a sensor for highly accurate distance measurement with a very high dynamic range and range walk compensation, said sensor being provided by means of an array of single photon avalanche photodiodes.

Abstract: 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.
