Abstract

본 발명은 입체프로젝터에 관한 것으로, 특히 2개의 마스터렌즈와 편광빔합성기를 형성하는 1개의 투사광학계를 구비하여 각각으로 입사되는 좌안용 영상과 우안용 영상을 합성하여 스크린에 투사되도록 함으로써, 광량을 손실없이 100% 사용할 수 있도록 하여 보다 선명하고 확실한 입체영상을 구현함은 물론 뛰어난 전력 절감을 이룰 수 있는 DMD 입체프로젝터에 관한 것이다. 구성은 광원과, 광원의 일측으로 형성된 칼라필터를 통과하여 진행하는 광을 혼합하여 진행시키는 복수의 글라스로드와, 진행하는 광을 좌안용 조명과 우안용 조명으로 분리하는 편광빔분리기와, 진행하는 좌안용 조명 및 우안용 조명의 방향을 원하는 방향으로 바꾸는 복수의 미러와 조명렌즈를 포함하여 이루어지는 조명광학계와; 상기 조명광학계를 통과하여 진행하는 좌안용 조명과 우안용 조명을 전반사시키는 복수의 전반사프리즘과; 전반사프리즘을 통해 진행하는 좌안용 조명 및 우안용 조명을 영상화하여 반사시키는 복수의 DMD와; 복수의 마스터렌즈를 갖고, 상기 각 마스터렌즈를 통해 진행하는 좌안용 영상 및 우안용 영상을 합성하여 투사시키는 투사광학계; 를 포함하여 이루어지는 것을 특징으로 한다.
