ABSTRACT:
An apparatus for the recognition an object in space in accordance with the pulsed time-of-flight principle. The apparatus has a pulsed laser and a photoreceiver arrangement which receives the light pulses reflected back from the object present in the space. The apparatus has a first light deflection apparatus which outputs a first angular position signal representative of its instantaneous angular position to the evaluation circuit, wherein the first light deflection apparatus is arranged rotatably or pivotably about a first axis of rotation and is made for the transmission of light pulses following one another at changing angles in a first plane, wherein a second light deflection apparatus is arranged between the first light deflection apparatus. The apparatus outputs a second angular position signal representative of its instantaneous angular position to the evaluation circuit which has a deflection plate which is arranged rotatably or pivotably about a second axis of rotation.
