Disclosed is a sensor array comprising several sensor devices, an electromagnetic radiation source, an electromagnetic radiation receiver, and a control device which is designed so as to emit electromagnetic radiation by means of the source and determine a distance that the electromagnetic radiation emitted by the source covers from a reflective surface of an object to the receiver by evaluating the reflected radiation. The inventive sensor devices of the several sensor devices operate at different frequencies or by time-division multiplexing. Also disclosed is a sensor device for a sensor array, the control device being designed so as to measure the distance at different frequencies or by time-division multiplexing. |
