Abstract[English]
An optical device, such a lens, or that includes a lens or lenses. The lens or lenses each have integrated therein a prism correction stage and an atoric correction stage. The prism correction stage operates to redirect an image of an object or scene so that the line of sight associated with the eye or eyes of a viewer are directed straight forward towards the lens or lenses, whereby the vergence angle between the eyes is reduced to zero or near zero degrees. The atoric correction stage operates to reshape the image so that the trapezoidal distortion caused by the redirection of the image due to the prism correction stage is at least reduced if not eliminated, and without affecting the reduction of the vergence angle as a result of the redirection of the image by the prism correction stage. In a case where the optical device has two lenses, the prism correction stage and the atoric correction integrated into each lens operate in such a way so as to reduce or elminate stereopsis and produce, for each eye, an identical, or monoscopic image such that the viewer sees the object or scene at optical infinity.[French]
Dispositif optique, comme une lentille, ou qui comprend une ou des lentilles. La ou les lentilles intègrent chacune un étage de correction de prisme et un étage de correction atorique. L'étage de correction de prisme sert à rediriger une image d'un objet ou d'une scène de telle sorte que la ligne de visée associée à l’œil ou aux yeux d'un observateur est dirigée directement vers l'avant en direction de la ou des lentilles, l'angle de vergence entre les yeux étant réduit à zéro ou proche de zéro degré. L'étage de correction atorique sert à remodeler l'image de telle sorte que la distorsion trapézoïdale provoquée par la redirection de l'image due à l'étage de correction de prisme est au moins réduite, voire éliminée, et sans affecter la réduction de l'angle de vergence suite à la redirection de l'image par l'étage de correction de prisme. Dans un cas où le dispositif optique comporte deux lentilles, l'étage de correction de prisme et la correction atorique intégrés dans chaque lentille servent à réduire ou à éliminer la stéréopsie et à produire, pour chaque œil, une image identique ou monoscopique de sorte que l'observateur voit l'objet ou la scène à l'infini optique.
