ABSTRACT:
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.
