摘要： The invention relates to a method for the recording of an object space with an opto-electronic distance sensor by a signal propagation time method, with a transmitter for transmitting optical signals, in particular those of a laser, and a receiver device for receiving optical signals, in particular laser radiation, which is reflected from objects located in the target space. The distance sensor is combined with a scanning device for deflecting the optical axes of the transmitter and receiver device, and it has an evaluation device, which from the propagation time or phase angle of the optical signal emitted ascertains distance values. Downstream of the scanning device, that is, out of the region oriented toward the distance sensor, part of the beam is split off from the beam path of the transmitter and/or receiver device and is directed to receiver diodes or the like, and from the corresponding signals, a pixel is ascertained and each pixel is assigned a distance value and a space angle.

摘要： Apparatus for measurement of the reception time of a pulse in a receiving system, which contains at least one receiving channel with a non-linear transmission response, which receiving channel produces at its output a received signal, having a memory, in which the received signals of reference pulses with a predetermined different amplitude are available as reference signals with respect to a time scale, and having an evaluation device, which is connected to the receiving system and to the memory and compares a received signal with each reference signal with a variant time offset in order to determine that reference signal and that time offset for which the comparison discrepancy is a minimum, and outputs this time offset as the reception time with respect to the time scale.
