Abstract

An embodiment of the invention relates to a sensor (3) providing at least one surveillance channel (SVC). The at least one surveillance channel (SVC) comprises a first and a second sub-channel (SUB1, SUB2), wherein the first sub-channel (SUB1) is formed by a first radiation emitter (T×1) and an individually assigned first detector (R×1), wherein the second sub-channel (SUB2) is formed by a second radiation emitter (Tx2) and an individually assigned second detector (Rx2), wherein an emitter control unit (35) is configured to control the radiation emitters such that the first radiation emitter (T×1) inputs a first stream (SBI1) of information into its allocated sub-channel (SUB1) and the second radiation emitter (Tx2) inputs a second stream (SBI2) of information into its allocated sub-channel (SUB2), wherein the first stream (SBI1) is inverse to the second stream (SBI2), and wherein an evaluation unit (36) is configured to evaluate detection signals of the first and second detector (R×1, Rx2) and generate a warning signal (WS) if the detection signal of the first detector (R×1) is not inverse or not sufficiently inverse according to a predefined deviation limit with respect to the detection signal of the second detector (Rx2).
