An optoelectronic arrangement for the detection of relative movements or relative positions of two objects, which comprises at least two position sensitive detectors, with each position sensitive detector being illuminated by a light emitting means in order to form a measuring cell, and a light emitting means illuminates two detectors each in order to form two measuring cells with a common light emitting means. Further, a force and/or moment sensor provided with this arrangement with a first board and a second board, with the first board and the second board being elastically connected with each other and movable relative to one another. Finally, a personal computer keyboard which is provided with such a force and/or moment sensor. |
