摘要： An optical projection system for use with a display surface includes at least one image source comprising an array of source image pixels, a projector to project a first projection of the array of source image pixels, and at least one mirror including at least one curved reflecting surface having a curved profile. The at least one curved reflecting surface is adapted to convert the first projection to a curved second projection directed onto the display surface to provide an array of displayed image pixels on the display surface corresponding to the array of source image pixels, wherein the array of displayed image pixels have constant pixel pitch among adjacent displayed image pixels.

摘要： An optical projection system includes an image source that is configured to generate an array of image pixels. A lens assembly is configured to project the array of image pixels onto a hemispherical surface at a projection angle greater than 180°. The lens assembly may include a wide-angle lens assembly and an image relay lens assembly that is configured to reduce dispersion in the array of image pixels between the image source and the wide-angle lens assembly. The wide-angle lens assembly may include a meniscus lens assembly and a wavefront shaping lens assembly. The lens assembly may be further configured to project the array of image pixels onto the hemispherical surface such that there is a constant angular separation between adjacent image pixels. An optical projection system may also include two image sources that are configured to generate first and second arrays of image pixels and two lens assemblies that are configured to respectively project the first and second arrays of image pixels at projection angles that are greater than 180° onto a surface in opposite directions of each other. The combination of the first and second arrays of image pixels may cover a continuous, 360° portion of the hemispherical surface.

摘要： An optical projection system includes a first optical image projector that is configured to generate a first array of image pixels having a first pupil associated therewith. A second optical image projector is configured to generate a second array of image pixels having a second pupil associated therewith. An optical element is configured to superimpose the first and second pupils to create a single exit pupil.
