Abstract:
1. An apparatus for recording an object space containing at least one object to be recorded, said apparatus comprising: opto-electronic range finder means including scanning means for deviating the optical axes of said transmitter and receiver units, said optical axes of the transmitter and receiver units extending substantially in parallel; optical means for directing said optical transmitter signals towards said object and to direct said optical receiver signals to said receiver unit, said optical means including hollow shaft means rotatably supported on said pedestal and defining an axis of rotation; a measuring head on said hollow shaft means for directing said optical transmitter signals towards said object and to obtain said optical receiver signals; mirror means arranged in a stationary fashion with respect to the measuring head, to deviate axially incident beams, in relation to the hollow shaft, in radial direction and vice-versa; an evaluation unit coupled to said range finder means to compare said optical transmitter signals and said optical receiver signals to determine distance values from said delay and to convert them into corresponding data elements, said evaluation unit being also coupled to said scanning means so as to determine spatial coordinates of said individual data elements and the beam deviation of the scanning device.
