Abstract: Highly accurate electro-optical time of flight distance measuring device for determining a distance to a target, including a transmitter for sending out a pulse shaped optical radiation to the target as well as a receiver for an optical signal built for turning the optical signal to an electrical signal, and a filter with a transfer function for filtering the electrical signal whereby the filter is built in such a way that its transfer-function is of at least 4th order, in particular 5th or 7th or higher order, so that aliasing is suppressed. Further a waveform-sampler, as an analog-to-digital-converter, for digitalizing the pulse shape from the filtered electrical signal as time- and value-quantized digital data, and a computation means for a numerical evaluation of the distance according to the pulse shape or a pulse shape representing numerical signature from the digital data.

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.

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: 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.
