Abstract
The invention relates to a method for producing picture element groups by means of laser rays in space and on a plane. The laser ray, functioning as a picture ray, is divided into a main ray and one or more secondary rays. The secondary rays are transformed into groups of individual picture elements by adapted devices. In the pictorial representation of 3D images, secondary images arise consisting of an individual picture group made of individual picture elements.
