Method and a device for optically detecting the position of an object by measuring the light reflected by this object

摘要

This detection method comprises: a step during which a receiver measures the quantity of light reflected by an object when the object is illuminated by an emitter for at least two different emitter-receiver pairs on the same side relative to the object, a step of calculating at least two characteristic values from the measured values, and a step of determining at least one position of the object by directly reading a table indexed by the two characteristic values, the content of said table being predetermined and set before said measurement step.
