A modular curved projection screen includes an outer structural component formed of multiple compound curved interlocking sections. Multiple inner compound curved screen components are each supported by a corresponding compound curved interlocking section and extend beyond edges of the interlocking sections. Responsive to interlocking the multiple compound curved interlocking sections, edges of adjacent screen components are compressed against each other to form a smooth concave projection viewing area supported by the outer structural component.

Embodiments include an inflatable support structure enclosing a region fillable by a fluid at a positive pressure above an atmospheric pressure. A flexible screen is attached to the support structure, a region between the flexible screen and the support structure fillable by a fluid at a negative pressure below the atmospheric pressure that holds the flexible screen in a shape suitable for image projection. A method according to embodiments includes inflating an inflatable support structure with a fluid at a positive pressure above an atmospheric pressure and removing fluid from a region between the support structure and a flexible screen attached to the support structure to hold the flexible screen in a shape suitable for image projection with the fluid at the negative pressure below the atmospheric pressure between the flexible screen and the support structure.

Embodiments include a light engine to generate pixels and a number of lenses positioned to receive pixels from the light engine and to project the pixels on to a field with a higher angular pixel density at an edge of the field than at a center of the field. A method according to embodiments includes generating pixels in a light engine, receiving the pixels from the light engine in a plurality of lenses, and projecting the pixels through the plurality of lenses on to a field with a higher angular pixel density at an edge of the field than at a center of the field.

Optical projection system and method of use

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&#xb0;. 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&#xb0; 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&#xb0; portion of the hemispherical surface.

Methods and systems for projecting images at greater than 180 degrees

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.

A visual workstation for use by a viewer includes a dome having an open front end and a truncated spherical inner dome surface. A work surface is disposed in front of and adjacent the dome front end. The work surface defines a viewer area on a side of the work surface opposite the dome. The viewer area is sized and configured to receive the viewer and is positioned relative to the spherical inner dome surface such that the viewer, when located in the viewer area, may view the spherical inner dome surface. A projector is disposed between the viewer area and the dome. The projector is operative to project a truncated spherical projection onto the inner dome surface.

A dual polarization optical projection system and method combines images from first and second image sources. The first image source includes a first array of image pixels wherein the first image source generates a first pixel image having a first polarization. The second image source includes a second array of image pixels wherein the second image source generates a second pixel image having a second polarization orthogonal to the first polarization. The first pixel image having the first polarization is combined with the second pixel image having the second polarization to form a combined pixel image. Each pixel of the combined pixel image corresponds to a combination of a first pixel from the first array of image pixels having the first polarization and a second pixel from the second array of image pixels having the second polarization.
