Abstract
The laser patterning device of this invention comprises a turntable on which is placed a processed member, and which rotates the member; a linear slider; a laser serving as a light source; an optical system, mounted on the slider, which condenses the laser light to form a laser spot on a substrate; and an optical modulator which changes the optical intensity of the laser spot. By performing laser patterning of a prescribed pattern on the processed member while moving the optical system mounted on the slider, while rotating the processed member by means of the turntable, a pattern having fine gray scales in the depth direction can be drawn with high precision and in a short amount of time.
