Abstract
In order to improve a sensor comprising an emitting element emitting a bundle of light rays in a direction of propagation, a receiving element receiving the bundle of light rays and having at least one receiving surface for the bundle of light rays, and an evaluating device generating an output signal of the sensor, such that exact determination of the deflection and the direction of deflection is possible, it is proposed that in each deflection position, a receiving surface be illuminated by only a partial bundle of rays of the bundle of light rays in the direction of deflection, that the receiving element generate for the receiving surface an integral intensity signal corresponding to the total intensity impinging upon this receiving surface and that the evaluating device detect the intensity signal and determine the deflection with a processor.
