| 摘要 |
The invention relates to a device for localizing modulated optical radiation sources, comprising a diaphragm unit (9; 12, 13) and a detector unit (2, 3), which is located behind the diaphragm opening (5, 7) in relation to radiation shining in along a main incidence axis, wherein the detector unit (2, 3) comprises at least three detector elements (4a-d; 6a-d) disposed around a center (Z2, Z3; Z), and the diaphragm unit comprises a diaphragm opening (5, 7), which is disposed centrally over the center (Z2, Z3; Z) and spaced apart from the center (Z2, Z3; Z) along the main incidence axis and covers all detector elements (4a-d; 6a-d) only partially as viewed along the main incidence axis (A2, A3; A). |
