LASER SOURCE COMPRISING AN ANGULAR SCANNING DEVICE

摘要

The invention generally pertains to the field of laser scanning devices including a coherent laser source emitting N elementary sub-beams and a first angular deflection system (1) including N phase shifters controlled by a phase lock device (3). The device of the invention includes a second angular deflection system (4) arranged in series with the first angular deflection system on the same optical axis, and including N identical collimation optical sub-systems mounted on a common mechanical structure, each sub-system being provided in front of one of said elementary sub-beams, and the structure being capable of a translation movement in a plane substantially perpendicular to the common optical axis of the beams so that the translation of the structure results in a simultaneous deflection of the N elementary sub-beams, the second deflection angle being added to the first deflection angle.
