Abstract

L'invention concerne un appareil de modification de la mise au point, conçu pour un balayeur optique et qui augmente la profondeur du champ de ce dernier. Ledit appareil est placé optiquement entre une source laser et un miroir de balayage et comporte plusieurs facettes courbes et plates en alternance. Autrement, un miroir piézoélectrique déformable peut être placé optiquement entre la source laser et un miroir de balayage à facettes plates de sorte que la profondeur de champ du balayeur optique soit augmentée.
