OPTOELEKTRONISCHER SENSOR
The sensor has two light transmitters (12) for sending light signals into a monitoring region. Codes of different transmitters are generated by quasi-orthogonal Hadamard-Walsh-codes or one of the codes in form a pseudo random code is assigned to the respective transmitter, where the pseudo random co...

| Zusammenfassung: | The sensor has two light transmitters (12) for sending light signals into a monitoring region. Codes of different transmitters are generated by quasi-orthogonal Hadamard-Walsh-codes or one of the codes in form a pseudo random code is assigned to the respective transmitter, where the pseudo random code forms a pattern sequence, which is divided into code segments. The other code is assigned to the other transmitter, and is generated by cyclic movement of the segments. The codes of the transmitters form a quasi-orthogonal code. |
