Title (EN) OPTICAL IMAGING SYSTEM
(FR) SYSTÈME D'IMAGERIE OPTIQUE
Abstract:
(EN) An optical imaging system (100) including an elongated lightguide (105) having pluralities of first and second light extractors (110) forming respective first and second patterns along the length of the lightguide is described. Light extracted by the first light extractors exit the lightguide primarily along a first direction toward a target location (150), and light extracted by the second light extractors exit the lightguide primarily along a second direction different from the first direction. The optical imaging system includes a first reflector (114) for receiving light exiting the lightguide primarily along the second direction and reflecting the received light toward the target location. The first reflector forms a first virtual image (132) of the second pattern behind the first reflector. The first pattern and the first virtual image are visible to a viewer (152) viewing the optical imaging system from the target location.
(FR) L'invention concerne un système d'imagerie optique (100) comprenant un guide de lumière allongé (105) ayant des pluralités de premiers et seconds extracteurs de lumière (110) formant des premiers et seconds motifs respectifs sur la longueur du guide de lumière. La lumière extraite par les premiers extracteurs de lumière sort du guide de lumière principalement le long d'une première direction vers un emplacement cible (150), et la lumière extraite par les seconds extracteurs de lumière sort du guide de lumière principalement le long d'une seconde direction différente de la première direction. Le système d'imagerie optique comprend un premier réflecteur (114) pour recevoir la lumière sortant du guide de lumière principalement le long de la seconde direction et réfléchir la lumière reçue vers l'emplacement cible. Le premier réflecteur forme une première image virtuelle (132) du second motif derrière le premier réflecteur. Le premier motif et la première image virtuelle sont visibles pour un observateur (152) observant le système d'imagerie optique à partir de l'emplacement cible.
