Abstract
(A1) Die vorliegende Erfindung bezieht sich im Bereich der diffraktiven Optik auf ein pixelliertes, diffraktives optisches Element zur Erzeugung eines beliebigen, quasi-kontinuierlichen Phasenhubs.

 

DE 102009037629 A1 UPAB: 20110302 NOVELTY - The diffractive optical element has an element section and multiple pixels for realizing an adjusting phase shift with a basis surface. A part of the pixels has a height profile with surfaces. An altitudinal belt is realized between the surfaces. The altitudinal belt is synchronized to an adjusted maximum phase shift of the diffractive optical element. The altitudinal belt has a constant height difference for the pixel with altitude profile. USE - Diffractive optical element for generating a phase distribution. ADVANTAGE - The diffractive optical element has an element section and multiple pixels for realizing an adjusting phase shift with a basis surface, and thus ensures improved diffractive optical element.
