Abstract: The invention relates to a method for creating an image on a surface or in a volume of a part (9), the image comprising a repetition of a pattern (11), the method comprising the following steps: —creating the pattern (11) on the surface or in the volume of the part (9) by shaping and focusing a coherent beam (8A), the pattern comprising at least two local contrast maxima; —carrying out a cycle of the following steps at least once: —moving the beam and the part relative to one another, and —creating the pattern (11) on the surface or in the volume by shaping and focusing the beam such that the patterns created do not overlap. The invention also relates to a system for creating an image on a surface or in a volume of a part using the method.

Abstract: The present invention relates to a micromachining method for patterning a material. The pattern is made up of a plurality of points. Said method includes the following steps: —emitting a spatially and temporally coherent pulsed light beam; —dynamically shaping said spatially and temporally coherent pulsed light beam in a modulation plane of a dynamic optical modulation device by applying at least one phase modulation so as to shape said light beam in accordance with the plurality of points forming the pattern; and —focusing the thus-shaped light beam, by means of a focusing device, on one surface of said material placed within a working plane in a Fourier configuration relative to the modulation plane.
