Abstract:
(EN) Provided is a laser light source shutter system using a variable-focus optical device. A light source shutter system, according to an embodiment of the present invention, comprises: a light source; a variable-focus optical device which transmits a beam irradiated from the light source; a pinhole which is positioned on an optical path on which the beam transmitted from the variable-focus optical device travels; and a controller for controlling the focal length of the variable-focus optical device to be the length from the variable-focus optical device to the pinhole or lengths other than the length from the variable-focus optical device to the pinhole. Therefore, by means of the variable-focus optical device (a variable-focus lens or a variable-focus mirror), a laser light source shutter having a high blocking rate at a low cost can be operated electronically i.e. free from vibration.
(FR) L'invention concerne un système d'obturateur de source de lumière laser utilisant un dispositif optique à focale variable. Un système d'obturateur de source de lumière, selon un mode de réalisation de la présente invention, comprend : une source de lumière ; un dispositif optique à focale variable qui transmet un faisceau émis depuis la source de lumière ; un trou sténopéïque qui est positionné sur un trajet optique sur lequel se déplace le faisceau émis par le dispositif optique à focale variable ; et un dispositif de commande permettant de commander la longueur focale du dispositif optique à focale variable de sorte à être équivalente à la longueur comprise à partir du dispositif optique à focale variable jusqu'au trou sténopéïque ou à des longueurs différentes de la longueur comprise à partir du dispositif optique à focale variable jusqu'au trou sténopéïque. Par conséquent, au moyen du dispositif optique à focale variable (un objectif à focale variable ou un miroir à focale variable), un obturateur de source de lumière laser ayant un taux de blocage élevé à faible coût peut être commandé électroniquement, à savoir sans vibrations.
(KO) 가변초점 광학소자를 이용한 레이저 광원 셔터 시스템이 제공된다. 본 발명의 실시예에 따른 광원 셔터 시스템은, 광원, 광원에서 조사되는 빔을 투과시키는 가변초점 광학소자, 가변초점 광학소자에서 투과된 빔이 진행하는 광 경로 상에 위치하는 핀홀 및 가변초점 광학소자의 초점거리를 '가변초점 광학소자로부터 핀홀까지의 거리' 또는 '그 외의 거리'로 제어하는 컨트롤러를 포함한다. 이에 의해, 가변초점 광학소자(가변초점 렌즈, 가변초점 거울)를 이용하여, 저비용으로 높은 차단율을 갖는 레이저 광원용 셔터를 진동으로부터 자유로운 전자식으로 구현할 수 있게 된다.
