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 Fresnel lens. The Fresnel lens includes an input side configured to receive the image and an output side, opposite the input side, configured to display the image. The input side includes a first facet angled to receive input light constituting at least a portion of the image. The input side also includes a second facet at least partially facing the first facet and a third facet linking the first facet to the second facet, wherein the third facet and the output side are substantially parallel.
