ABSTRACT:
The invention proposes a sensor array having a plurality of sensor devices comprising a source of electromagnetic radiation, a receiver for the electromagnetic radiation and a control device, the control device being designed to use the source to emit electromagnetic radiation and being designed to determine a distance covered by electromagnetic radiation, which is emitted by the source, from a reflection surface of an object to the receiver by evaluating the reflected radiation. According to the invention, the sensor devices of the plurality of sensor devices operate at different frequencies or using time-division multiplexing. The invention also proposes a sensor device for a sensor array, the control device being designed to measure the distance at different frequencies or using time-division multiplexing.
