Abstract
The invention relates to a method for producing a homogenized distribution of light quantity with a spatial light modulator that comprises a multitude of controllable and tiltable micro-mirrors that are arranged in rows and columns, in which the light of a spatially emitting light source is projected by means of an optical system and an illuminated field of the projected light source is guided over a projection surface, whereby, towards the middle of the illuminated field, an increasing number of pixels is not being illuminated such that the time integral attains a homogenization of the light intensity of all pixels that are illuminated on the projection surface. The invention also relates to a rapid prototyping method, in which a liquid light-curing plastic material is illuminated by means of a method of this type, preferably is illuminated by UV light, whereby the illuminated field is projected onto the surface of the plastic material and the plastic material is cured through the illumination of the illuminated field.
