Abstract
An optoelectronic device for acquiring images of planes, such as bar codes, includes a deflector for deflecting an incident beam emitted by a light source such as an oscillating or rotating cyclic polygonial deflector or mirror. A driver osscilates or rotates the deflector in such a way that the incident beam describes, during each cycle, angular scanning adapted to generate at least one elementary scanning line on the plane. A closed loop control circuit controls the driver and is connected, on the one hand, to the clock in order to receive the transfer signal &PHgr; and, on the other hand, to the driver and adapted to synchronize the beginning of each scanning cycle in phase and frequency with the signal &PHgr; emitted by the clock.
