A system for recording an object space has a opto-electronic distance sensor which uses a signal propagation time method, and a transmitter for transmitting optical, signals, as well as a receiver (E) for receiving optical signals, reflected by objects located in the target space. The system comprises a scanner for deflecting optical axes of the transmitter and receiver (S and E). The optical axes of the transmitter and receiver (S and E) for example, are substantially parallel. An evaluation system determines distance values from the propagation time or phase position of the transmittal optical signals, and the space coordinates of the individual data elements result from the distance values and the beam deflection implemented by the scanner. The system comprises a rotary measurement head mounted on a pillow block, and a mirror system fixed relative to the measurement head, which deflects beams axially incident on the hollow shaft in the radial direction and vice versa. The radiation from stationary transmitter (S) can be introduced in the axial direction relative to the hollow shaft and can be transmitted in the radial direction through the mirror system. The radiation reflected by the targets located in the object space, can be deflected by the mirror system in the direction of the axis of the hollow shaft and be supplied to the receiver (E), which is also stationary.
