Sony patents beam shaper for precise laser machining
Sony describes a device that uses a digital screen to shape a laser beam into specific patterns. It combines this with a lens that can change its focus to hit a target accurately.
In the filing’s own words
A beam shaping device according to one embodiment of the present disclosure allows wide range and high accuracy modulation of an irradiation pattern to be performed. The beam shaping device of the present disclosure includes a spatial light modulator ( 10) of phase modulation type that displays a phase pattern corresponding to an irradiation pattern to be applied to an object ( 50), and an optical unit ( 21) that has a focal length variable and that converges light modulated by the spatial light modulator on the object.
What exactly they claim (claim 1)
1. A beam shaping device comprising: a spatial light modulator of phase modulation type that displays a phase pattern corresponding to an irradiation pattern to be applied to an object; and an optical unit that has a focal length variable and that converges light modulated by the spatial light modulator on the object.
