Title (EN) MULTI-SEGMENTED AIMING DIFFRACTIVE OPTICAL ELEMENTS
(FR) ÉLÉMENTS OPTIQUES DIFFRACTIFS DE VISÉE À MULTIPLES SEGMENTS
Abstract: front page image
(EN)A system having a light source generating a light beam, a collimating lens collimating the light beam into a collimated light beam and a pattern generating element comprising a diffractive optical element portion and a refractive optical element portion, the pattern generating element creating a target pattern from the collimated light beam incident on the pattern generating element.
(FR)L'invention porte sur un système ayant une source de lumière générant un faisceau lumineux, une lentille de collimation collimatant le faisceau lumineux en un faisceau lumineux collimaté et un élément de génération de motif comportant une partie d'élément optique de diffraction et une partie d'élément optique de réfraction, l'élément de génération de motif créant un motif cible à partir du faisceau lumineux collimaté incident sur l'élément de génération de motif.
