Abstract: The invention relates to a distance measuring method comprising at least the step of emitting at least one measurement signal to a target object, in which at least one start signal is produced, and the measurement signal is back scattered from the target object as a target signal. Said target signal and optionally also the start signal is sampled in a first and a second sampling at various sampling rates and determines the distance to the target object from the relative position from the start signal and the target signal.

Abstract: The invention relates to a distance measuring method comprising at least the step of emitting at least one measurement signal to a target object, in which at least one start signal is produced, and the measurement signal is back scattered from the target object as a target signal. Said target signal is sampled at a sampling frequency and the relative position of the start signal and the target signal is determined for deriving a distance to the target object from the relative position from the start signal and the target signal. The sampling frequency can be adjusted and is set in accordance with a large distance to the target object.

Abstract: A total station including an electro-optical distance measuring unit and a scanning functionality is disclosed. The total station may include an analysis unit for analysis of the registered measuring signal data and conversion thereof into scanning points for a point cloud, whereby a point cloud having the scanning points can be generated. The distance measuring unit may be configured in such a manner that the distance measurement can be carried out by means of runtime measurement and/or waveform digitizing (WFD). In addition, the total station may have a program storage unit which may provide at least two scanning modes, wherein the at least two scanning modes differ at least in a measuring rate such as, for example, in the number of scanning points per unit of time.

Abstract: Some embodiments of the invention may include an electro-optical distance measurement method having at least one emission of a light signal, in particular of laser light, from at least one light source onto a target object, detection of a fraction of the light signal returning from the target object using a detector and a signal processing electronics system connected downstream from the detector, and/or determination of a distance to the target object. In some embodiments, the emitted light signal comprises in this case a sequence of sequential elements of, in each case at least one light pulse and one light signal train. In some embodiments, the light pulses each have a higher intensity amplitude than the light signal trains. Some embodiments may also an electro-optical distance meter having the features analogous to The distance measurement method according to the invention.

Abstract: An optical measuring device having a base for placing the measuring device and a targeting unit that is rotatable with respect to the base and defines a target axis for targeting a target object that is to be measured. The targeting unit has a first beam path for emitting optical measurement radiation in the direction of the target object that is to be measured. The targeting unit furthermore has a diffractive optical element (DOE), which is arranged or arrangeable in the beam path such that the optical measurement radiation is homogenized.
