Arrangement for the detection of relative movements or relative positions of two objects
First Claim
1. An optoelectronic arrangement for the detection of relative movements or relative positions of two objects, which comprises at least two position sensitive detectors (42, 62), with each position sensitive detector being illuminated by a light emitting means in order to form a measuring cell, characterised in that a light emitting means illuminates at least two detectors (42, 62) each in order to form two measuring cells with a common light emitting means.

Abstract
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.
