Abstract
(DE)
Verfahren zur Erzeugung von Bildpunktgruppen mit Laserstrahlen im Raum und in der Ebene, wobei der Laserstrahl in seiner Funktion als Bildstrahl in einen Hauptstrahl und einen oder mehrere Nebenstrahlen aufgeteilt wird, und die Nebenstrahlen durch geeignete Vorrichtungen in Gruppen von einzelnen Bildpunkten umgewandelt werden, wodurch in der bildlichen Darstellung von Raumbildern neben den Hauptbildern Nebenbilder entstehen, die sich als Gruppe aus einzelnen Bildpunkten zusammensetzen.
(EN)
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.
(FR)
La présente invention concerne un procédé de production de groupes de points d'image au moyen de rayons laser dans l'espace ou dans le plan. Le rayon laser, dans sa fonction de rayon d'image, est divisé en un rayon principal et en un ou plusieurs rayons secondaires. Les rayons secondaires sont transformés en groupes de points d'image individuels par des dispositifs adaptés. Ainsi, dans la représentation en image des images en trois dimensions, des images secondaires composées de groupes de points d'image individuels apparaissent en plus des images principales.
