Abstract: front page image
(EN)The present invention presents a stereoscopic image device comprising: a first polarizing beam splitter (PBS) for spatially splitting image light emitted from a projector into one or more transmitted light beams and one or more reflected light beams according to polarization components, and emitting the split image light; a first modulator performing modulation so as to have circularly polarized light beams different from each other, according to the alternate emitting, to a left image and a right image, of transmitted light in a time-division manner, such that the transmitted light beams are emitted at a screen; a second modulator performing modulation so as to have circularly polarized light beams different from each other, according to the alternately emitting, to a left image and a right image, of reflected light in a time-division manner, such that the reflected light beams are emitted at a screen; and a second PBS arranged between the second modulator and 3D glasses so as to block light having a specific polarization component, which is not converted into circularly polarized light by the second modulator.
(FR)La présente invention concerne un dispositif d'image stéréoscopique qui comprend : un premier séparateur de faisceau polarisant (PBS) destiné à séparer spatialement une lumière d'image émise par un projecteur en un ou un plusieurs faisceaux de lumière transmise et un ou plusieurs faisceaux de lumière réfléchie, selon des composantes de polarisation, et à émettre la lumière d'image séparée; un premier modulateur qui effectue une modulation de façon à avoir des faisceaux de lumière à polarisation circulaire différents les uns des autres, selon l'émission alternée, vers une image de gauche et une image de droite, de lumière transmise en répartition dans le temps, de sorte que les faisceaux de lumière transmise soient émis au niveau d'un écran; un second modulateur qui effectue une modulation de façon à avoir des faisceaux de lumière à polarisation circulaire différents les uns des autres, selon l'émission alternée, vers une image de gauche et une image de droite, de lumière réfléchie en répartition dans le temps, de sorte que les faisceaux de lumière réfléchie soient émis au niveau d'un écran; et un second PBS placé entre le second modulateur et des lunettes 3D de façon à bloquer la lumière qui possède une composante de polarisation spécifique, qui n'est pas convertie en lumière à polarisation circulaire par le second modulateur.
(KO)본 발명에서는 프로젝터로부터 조사된 영상광을 편광성분에 따라 하나 이상의 투과광 및 하나 이상의 반사광으로 공간적으로 분할하여 조사하는 제 1 편광 광분할기(PBS); 상기 투과광이 시분할적으로 번갈아 좌측 영상 또는 우측 영상으로 조사됨에 따라 서로 다른 원편광을 가지도록 변조를 수행하여 스크린으로 조사되도록 하는 제 1 변조기; 상기 반사광이 시분할적으로 번갈아 좌측 영상 또는 우측 영상으로 조사됨에 따라 서로 다른 원편광을 가지도록 변조를 수행하여 상기 스크린으로 조사되도록 하는 제 2 변조기; 및 상기 제 2 변조기와 3D 안경 사이에 배치되어 상기 제 2 변조기에 의해 원편광으로 변환되지 않은 특정 편광 성분의 광을 차단하는 제 2 PBS를 포함하는 입체영상 장치를 제안한다.
