Zusammenfassung:	The system has a light source e.g. laser diode, for emitting a laser light beam, and a primary detection device for detecting a digital optical code. The device is connected to an electronic processing unit, and comprises a detection cell row (8). A rotating body has a series of groups of n-cells for generating the same optical code at the device with spatial gap of luminous spots (9) based on luminous spots of codes of adjacent cells of the same group. The spatial gap of the luminous spots is applied to secondary detection devices (12, 13) to detect fractions of the optical code.
