Abstract
The invention relates to an optoelectronic sensor, in particular a bar code reader, with an optical receiving system positioned in front of a light receiver for the deflection of a light beam reflected from an object, in particular a bar code, onto the light receiver. Through the provision of aperture diaphragms, or a plurality of light receivers, or regions with different image forming characteristics in the optical receiving system, a situation is achieved in which the receiving characteristics of the overall system, which result by reason of the shape of the sensing laser beam, as a result of the characteristics of the electronic evaluation system and as a result of different light intensities of the light returned, for example from a bar code, are optimized for different sensing distances.
