摘要： The wide angle lens system described herein allows projection devices (e.g., rear projection display devices) to be more compact than would otherwise be possible. The lens system includes a wide angle lens stage and a relay lens stage. When operating as a projection device, the relay lens stage projects a distorted intermediate image to the wide angle lens stage, which projects the image for display. The distortion cause by the relay lens stage compensates (i.e., is approximately equal and opposite) for the distortion caused by the wide angle stage. The distortion can be the image shape and/or the focal plane. When operating as a taking device, the wide angle stage provides a distorted image to the relay lens stage, which compensates for the distortion and provide a less distorted, or even non-distorted image, for capture.

摘要： A zoom lens system includes: a primary image forming lens group that forms light from an object side into an intermediate image and a relay lens group that forms light from the intermediate image into a final image. The primary image forming lens group includes, in order from the object side, a first fixed lens group G1 with negative refractive power, a stop St, and a second fixed lens group G2 with positive refractive power, and the relay lens group includes, in order from the object side, a third fixed lens group G3 with negative refractive power, a first moving lens group G4 with positive refractive power, and a second moving lens group G5 with positive refractive power.

摘要： A rear projection display device is provided. In an embodiment, the display device includes a laminate screen including a microstructure lamina having a non-planar input surface, a substantially planar output surface and a first index of refraction. The laminate screen further may include a diffusion screen lamina having a substantially planar input surface, an output surface and a second index of refraction. The diffusion screen lamina may be in optical communication with the microstructure lamina. Moreover, the planar output surface of the microstructure lamina and the planar input surface of the diffusion screen lamina may be in facing relationship.
