| 摘要 |
The invention relates to an optical sensor arrangement with a light transmission device (1; 15), which directs an essentially parallel light bundle via an optical sensor element (7; 22) to a light receiver device (9; 15, 26). Between the light transmitter device and light receiver device is arranged either an arrangement of a first and second lens (6, 8) for the production of a convergent light bundle or one lens (20) for the production of a convergent light bundle, of which the focus lies on a reflective layer (21). <IMAGE>
