摘要： A projection display apparatus includes: an illumination optical unit which emits beams; an image display element which modulates the beams according to image information; a spatial-beam changing unit which changes spatial positions of the beams emitted from the illumination optical unit; and a uniform-beam distribution unit, disposed between the spatial-beam changing unit and the image display element, which uniformly distributes the beams. The spatial-beam changing unit includes a moveable prism, a movement of which changes the spatial positions of the beams emitted therefrom.

摘要： A projection apparatus including a light source which generates light beams, an optical projection system which projects the light beams generated by the light source onto a screen, and a reflection device which is positioned between the light source and the optical projection system. The reflection device includes a plurality of mirrors capable of reflecting incident beams generated by the light source to travel toward the optical projection system. The projection apparatus also includes an optical illumination system which is positioned in an optical path between the light source and the reflection device and is tilted or decentered with respect to the optical axis of the light source to allow light beams generated by the light source to enter the reflection device at a predetermined angle. Since the optical paths of the optical projection system and the optical illumination system can be separated from each other by installing lenses in the optical illumination system, it is possible to manufacture the projection apparatus through a simple assembly and improve optical efficiency and a contrast ratio.

摘要： An optical illumination system and an image projection system including the same include a light source, at least one illuminating lens and a Mangin mirror that illuminate light emitted from the light source on a predetermined reflective device, the Mangin mirror including a concave refracting surface that refracts and transmits light incident from the illuminating lens, and a convex reflecting surface disposed behind the concave refracting surface to internally reflect the light refracted by the concave refracting surface back toward the concave refracting surface and tilted with respect to the illuminating lenses. The light reflected from the convex reflecting surface and then refracted through the concave refracting surface propagates along a path that is different from a path of the light emitted from the illuminating lens.
