Abstract: An image projection system has a first lens with a defined entrance pupil. An image source has an image field and a defined exit pupil. The exit pupil of the image source is configured such that the exit pupil of the image source underfills the entrance pupil of the lens for portions of the image source that are not in the center portion of the image field.

Abstract: Method and apparatus are provided for displaying an image to a viewer with reduced visual artifacts. The apparatus comprises a display panel for forming the image using an array of pixels with distributed active regions, and a viewing arrangement optically situated between the display panel and the viewer for transferring the image formed on the display panel to the viewer with limited angular pixel subtense. The distributed active regions of the pixels are desirably divided into at least two simultaneously switched portions at least partly separated by or surrounding a significant portion of the non-switchable region. First order spatial harmonics and associated artifacts are reduced by the distributed apertures and second order and higher harmonics are reduced by limiting the pixel subtense angle seen by the viewer. A significant reduction in visual artifacts arising from the periodic structure of the display panel is obtained.

Abstract: Methods and apparatus are provided for chromatic vignetting in lens systems. The apparatus includes a projection lens unit having an aperture stop, and a selective filter positioned at the aperture stop. The aperture stop defines a ray bundle boundary of an image passing therethrough. The selective filter includes a transmission area having an optical perimeter based on the ray bundle boundary, and a wavelength band filter partially extending from the optical perimeter into the transmission area. The projection lens unit may be used with an illumination unit having a light source and optics conditioning the light from the light source prior to illumination of a light valve. The selective filter may optionally be positioned at a conjugate plane to the aperture stop in the illumination unit. The method includes passing ray bundles through a lens system having an aperture stop, and selectively filtering one of at least one wavelength band at a boundary of the ray bundles at the aperture stop and at least one wavelength band at a boundary of the ray bundles at a conjugate plane.

Abstract: An arm holding device. The device includes a waist band, a groin strap fitted with an attachment/release buckle, and arms bands which are slidably attached to the waist band. The attachment/release buckle on the groin strap makes placing and removing the device on the patient a simple process. The slidably attached arm bands give the patient limited movement of their arms, while effectively holding the arms of the patient to prevent the patient from aggravating an injury. The device is made of flexible materials to provide as much comfort as possible for the patient, while still being effective.

Abstract: A beam folder increases optical length with polarizing beam splitters and reflectors that repolarize a beam by retarding it. An incident beam encounters the beam splitters multiple times, and are both passed and rejected by the same splitters. The splitters and repolarizing reflectors can be shaped to perform optical functions in a smaller volume. Valves and controls can vary the beam intensity and combine multiple beams. Applications include projection, imaging, collimating, mixing, and balancing.

Abstract: Methods and apparatus are provided for color correction and contrast enhancement of projection displays. A visual display system includes a projector having a light source with a fixed spectral output, a display screen receiving the output of the projector and emitting a diffused output, and a color correction contrast enhancement filter positioned between the diffusing screen and a viewer. The filter differentially attenuates primary colors of the emission from the diffusing screen. The method includes projecting a light output from a light source having a fixed spectral output onto a diffusing screen, and attenuating primary colors of the emission from the diffusing screen with a light filter positioned adjacent to the diffusing screen.
