1. one kind is used for sensor device that object (6) is carried out optical detection, and this sensor device has:



  • first transmitting apparatus (3), it is arranged to and sends the first transmission ray;



    first receiving equipment (11), it is arranged to and receives the first reception ray;



    second receiving equipment (12), it is arranged to and receives the second reception ray;

    And●

    analytic unit (16), it is connected on first receiving equipment (11) and second receiving equipment (12) afterwards,Wherein the first reception ray and/or the second reception ray have the scattered light that is produced at the first transmission ray under the situation that object (6) is located to be scattered at least in part;

    AndWherein analytic unit (16) and first receiving equipment (11) and second receiving equipment (12) are coupled, and make it possible to the difference signal between second output signal of first output signal of analytic unit (16) conveying first receiving equipment (11) and second receiving equipment (12).
