Title
(EN) DISTANCE SENSOR
(FR) CAPTEUR DE DISTANCE
Abstract
(EN)
In one embodiment, a distance sensor includes a projection light source, a first light guiding means positioned to guide light emitted by the projection light source, a diffractive optical element positioned to split the light guided by the first light guiding means into a plurality of projection beams traveling in different directions, and an image capturing device positioned to capture an image of a field of view, including a projection pattern created by an incidence of the plurality of projection beams on an object in the field of view.
(FR)
Dans un mode de réalisation, un capteur de distance comprend une source de lumière de projection, un premier moyen de guidage de lumière positionné de manière à guider la lumière émise par la source de lumière de projection, un élément optique de diffraction positionné pour diviser la lumière guidée par le premier moyen de guidage de lumière en une pluralité de faisceaux de projection se déplaçant dans des directions différentes, et un dispositif de capture d'image positionné pour capturer une image d'un champ de vision, comprenant un motif de projection créé par une incidence de la pluralité de faisceaux de projection sur un objet dans le champ de vision.
