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: The invention relates to a method for surveying at least one target using a geodetic device. According to said method, a camera of the device captures a visual image and surveys an angle and/or a distance to the target with geodetic precision, the angle and/or distance surveillance being supported or controlled by the visual image. At the same time of capture of the visual image at least two distance points of a distance image are captured as the spatial distribution of discrete distance points in the area of detection. When the visual image and the distance image are correlated with each other, the target is recognized or the measuring process is controlled.
