Abstract:
(EN) Provided are a rotating zoom lens system and a method for realizing the same. The rotating zoom lens system comprises a first lens assembly (1), a second lens assembly (2), and a liquid crystal module (3). An optical axis of the first lens assembly (1) and an optical axis of the second lens assembly (2) are arranged on the same straight line. A focal length of the stacked first lens assembly (1) and second lens assembly (2) changes with a change in relative angles of the first lens assembly (1) and second lens assembly (2). The liquid crystal module (3) is installed at one side of the first lens assembly (1) or one side of the second lens assembly (2). The rotating zoom lens system performs zooming by changing relative angles of lens assemblies without having to adjust a distance between the lens assemblies, such that the system has a compact size, can be manufactured easily, and is applicable to the field of optical instruments.
(FR) La présente invention concerne un système de zoom rotatif, et un procédé permettant de réaliser ce système de zoom rotatif. Le système de zoom rotatif comprend un premier ensemble lentille (1), un second ensemble lentille (2), et un module à cristaux liquides (3). Un axe optique du premier ensemble lentille (1) et un axe optique du second ensemble lentille (2) sont placés sur la même ligne droite. Une longueur focale du premier ensemble lentille (1) et du second ensemble lentille (2) empilés change lorsque des angles relatifs de ce premier ensemble lentille (1) et de ce second ensemble lentille (2) changent. Le module à cristaux liquides (3) est installé sur un côté dudit premier ensemble lentille (1) ou un côté dudit second ensemble lentille (2). Le système de zoom rotatif effectue un zoom grâce à un changement d'angles relatifs des ensembles lentilles sans avoir à ajuster une distance entre les ensembles lentilles, de telle sorte que le système ait une taille compacte, puisse être fabriqué facilement, et puisse être appliqué au domaine des instruments optiques.
(ZH) 一种旋转变焦透镜系统及其实现方法,包括第一透镜组(1)、第二透镜组(2)和液晶模块(3)。第一透镜组(1)的光轴和第二透镜组(2)的光轴在同一直线上,第一透镜组(1)和第二透镜组(2)叠加后的焦距随着第一透镜组(1)和第二透镜组(2)的相对角度变化而变化,液晶模块(3)安装在第一透镜组(1)的一侧或者第二透镜组(2)的一侧。旋转变焦透镜系统通过改变透镜组之间的相对角度来变焦,不需通过调整透镜组之间的距离来变焦,使得系统的体积小,制造简单,可应用于光学仪器领域。
