Abstract:
(EN) The present invention relates to a virtual moving lens. The virtual moving lens comprises: a first polarization dependent lens formed so as to be driven as a lens according to a polarization direction of incident light; and a second polarization dependent lens formed so as to be driven as a lens according to a polarization direction of incident light, and stacked on the surface of the first polarization dependent lens, wherein the polarization direction in which the first polarization dependent lens is driven as a lens and the polarization direction in which the second polarization dependent lens is driven as a lens are formed to be perpendicular to each other, such that only one of the first polarization dependent lens or the second polarization dependent lens is driven as a lens according to the polarization direction of incident light. It is preferable that a valley of the first polarization dependent lens and a valley of the second polarization dependent lens are disposed to be spaced apart from each other such that a focal position moves and varies according to the polarization direction of incident light. The virtual moving lens according to the present invention is formed by stacking polarization dependent lenses, which are determined to be driven as lenses according to the polarization direction of incident light, and switches the polarization direction of incident light by using a polarization switching unit driven at a high speed according to an applied voltage, thereby enabling the focal position to vary without a physical position movement of the lens.
(FR) La présente invention concerne une lentille mobile virtuelle. La lentille mobile virtuelle comprend : une première lentille dépendante de la polarisation formée de manière à être entraînée en tant que lentille selon une direction de polarisation de la lumière incidente; et une seconde lentille dépendante de la polarisation formée de manière à être entraînée en tant que lentille selon une direction de polarisation de la lumière incidente, et empilée sur la surface de la première lentille dépendant de la polarisation, la direction de polarisation dans laquelle la première lentille dépendant de la polarisation est entraînée en tant que lentille et la direction de polarisation dans laquelle la seconde lentille dépendant de la polarisation est entraînée en tant que lentille sont formées pour être perpendiculaires l'une à l'autre, de telle sorte que seule l'une de la première lentille dépendant de la polarisation ou de la seconde lentille dépendante de la polarisation est entraînée en tant que lentille selon la direction de polarisation de la lumière incidente. Il est préférable qu'un creux de la première lentille dépendant de la polarisation et un creux de la seconde lentille dépendant de la polarisation soient disposés de manière à être espacés l'un de l'autre de telle sorte qu'une position focale se déplace et varie en fonction de la direction de polarisation de la lumière incidente. La lentille mobile virtuelle selon la présente invention est formée par empilement de lentilles dépendantes de la polarisation, qui sont déterminées comme étant entraînées en tant que lentilles selon la direction de polarisation de la lumière incidente, et commute la direction de polarisation de la lumière incidente à l'aide d'une unité de commutation de polarisation commandée à une vitesse élevée en fonction d'une tension appliquée, ce qui permet à la position focale de varier sans mouvement de position physique de la lentille.
(KO) 본 발명은 가상 이동 렌즈에 관한 것이다. 상기 가상 이동 렌즈는, 입사되는 빛의 편광 방향에 따라 렌즈로 구동되도록 구성된 제 1 편광 의존형 렌즈; 및 입사되는 빛의 편광 방향에 따라 렌즈로 구동되도록 구성되며, 상기 제 1 편광 의존형 렌즈의 표면에 적층된 제 2 편광 의존형 렌즈;를 구비하고, 상기 제 1 편광 의존형 렌즈가 렌즈로 구동되는 편광 방향과 상기 제 2 편광 의존형 렌즈가 렌즈로 구동되는 편광 방향은 서로 수직이 되도록 구성되어, 입사광의 편광 방향에 따라 상기 제 1 편광 의존형 렌즈와 제 2 편광 의존형 렌즈 중 하나만 렌즈로 구동되도특 구성된다. 상기 제 1 편광 의존형 렌즈의 골과 제 2 편광 의존형 렌즈의 골이 서로 이격되게 배치되어, 입사되는 빛의 편광 방향에 따라 초점 위치가 이동되어 가변되는 것이 바람직하다. 본 발명에 따른 가상 이동 렌즈는 입사광의 편광 방향에 따라 렌즈로의 구동이 결정되는 편광 의존형 렌즈들을 적층하여 구성하고, 인가 전압에 따라 고속 구동되는 편광 스위칭부를 이용하여 입사광의 편광 방향을 스위칭시킴으로써, 렌즈의 물리적인 위치 이동없이 초점 위치를 가변시킬 수 있는 것을 특징으로 한다.
