Abstract:
1. An optical sensor for detecting a signal emitted by a light source, for use in a placement detection system, the optical sensor comprising: a line-sensor having a detection line comprising a pixel line consisting of pixels, an optical imaging means imaging the light of the light source onto a light strip being cross-directional to the detection line of the line-sensor, the optical imaging means being arranged with a distance from the line-sensor, the light strip having strip-boundary transitions on each of its two edges in the direction of the detection line, wherein the detection line comprises a pixel line, in which there are gaps between adjacent pixels, the optical sensor has a detection range ensuring that at least one of the strip-boundary transitions always falls at least in part onto a pixel, and the optical imaging means increasing-in the direction of the detection line-the dimension of the strip-boundary transitions.
