Claims (7)

1. An optical-electronic distance finder system that operates on a time-of-transmission method consists of a transmitter (S) for transmitting an optical signal, specifically a laser signal, and a receiver (E) for the optical signal. The laser beam reflected from an object at a target distance is then deflected by a scanner that deflects the optical axes of the transmitter and receiver (S or E). In an optimal configuration, the deflection is perpendicular to each other in two directions, where the optical axes of the transmitter and receiver (S or E) are essentially parallel. A processor then provides the distance value from the time-of-transmission signal, or the phase position of the emitted optical signal. The coordinates of each data set are determined by the distance value and beam deflection from the scanner, which has the following characteristics: The rotating probe (8) is supported by the path of the hollow axis (33, 34) of the levers (21, 22, 24) and a set of mirrors (41, 42) that are positioned in reference to the probe (8). In this way, the axial incident beam is deflected radially from the hollow axis (33, 34) and vice versa. The ray emitted from the stationary transmitter (S) can be directed axially in reference to the hollow axis (33, 34) and radially by the set of mirrors (41, 42). The ray reflected from the target at a distance from this object is deflected by the set of mirrors (41, 42) in the direction of the axis of the hollow axis (33, 34) and can be directed to the same stationary receiver (44). 2.
