ABSTRACT:
To determine the position of a control stick which can be adjusted in three axes, reliably and accurately in all three axes in a constructionally simple, compact and light-weight manner by means of a single sensor in an opto-electronic fashion, the sensor according to the invention contains a beam emitter which is fixedly connected with the control stick and emits at least two mutually spatially separate light beams. A stationary, light-sensitive detector mosaic situated along the whole adjusting range of the control stick in the beam path of both light beams, determines the position coordinates of the two light spots generated thereon by the light beams. An analyzing circuit determines the rolling, pitching and yawing position of the control stick from the position coordinates of the two light spots.
