Beschreibung
Zusammenfassung:	An optical system is claimed for the treatment of materials incorporating a luminous source (1) illuminating an inlet surface of a spatial light modulator (3) which is destined to transmit a modulated light beam onto a material to be treated. The system comprises:-a) a luminous source (1), such as a laser power source; b) an optic (2) for the spatial expansion of a light beam in a manner that spreads the energy of the beam across the inlet surface of a spatial light modulator (3); c) a spatial light modulator (3), such as a liquid crystal screen; d) an optic (4) for the spatial concentration of the modulated light beam in a manner to focus the beam onto the component to be treated; and e) a control system (15), such as an electronic control system, that allows control of the spatial light modulator (3). The modulation induced may be reconfigured by this control system and may be synchronised with the control of the emission form the luminous source so that for each control of luminous emission it is possible to modify the display of the spatial modulator (3). Système optique pour le traitement de matériaux comprenant une source lumineuse (1) éclairant une surface d'entrée d'un modulateur spatial de lumière (3) lequel est destiné à transmettre un faisceau de lumière modulée à un matériau à traiter. Ce système comporte:- une optique (2) d'expansion spatiale du faisceau de façon à étendre l'énergie du faisceau selon la surface d'entrée du modulateur spatial de lumière (3); - une optique (4) de concentration spatiale du faisceau modulé par le modulateur spatial de lumière (3) de façon à focaliser le faisceau.Différentes variantes de réalisation de l'invention sont prévues.Applications: Traitement de matériaux tel que notamment la gravure superficielle d'objets.
