    摘要: A light source assembly comprises a light pipe, a first color light source at a first tapered light collector, a second light source at a second tapered light collector, and at least a first dichroic filter operative to pass first color light and to reflect second color light toward a light output port. A light valve may be positioned to receive light from the light pipe. One or more light entrances to the light pipe may have a filter, e.g., a short wave pass filter, oriented in a plane generally parallel to the axial optical pathway.

    摘要: Methods and apparatus for enhancing the performance of reflective LCD systems. The high-contrast color-splitting prism system utilizes a "double-pass" prism assembly. Polarized light enters the prism assembly, is color-split and is emitted as separate colors to reflective imagers which reflect each color in accord with a desired image. The reflected light is passed, once again, through the prism assembly where the separate colors converge and the convergent light is emitted to a projection lens for display of the image on a screen. At least one zero-incidence waveplate compensator is positioned between one reflective imager and the prism assembly. The waveplate compensator effectively decreases the unwanted polarized light entering the prism assembly for the second pass-through, thereby increases the polarization purity of the light that is emitted from the prism assembly to the projection lens to yield a high-contrast projection image.

    摘要: An anamorphic eyepiece. In one implementation, the eyepiece is for use with a display where both the eyepiece and display are head-mounted, with the eyepiece projecting an image from the display into the user's eye. The display has high resolution in a horizontal direction, preferably at least 2000 pixels, but the image produced by the display is compressed in aspect ratio. The anamorphic eyepiece decompresses the aspect ratio.

    摘要: A light source assembly (212) for providing a homogenized light beam (224) includes a first light source (234), a second light source (236), and an optical pipe (228) that defines a pipe passageway (228A). The first light source (234) generates a first light (234A) that is directed into the pipe passageway (228A) at a first region (228I). The second light source (236) generates a second light (236A) that is directed into the pipe passageway (228A) at a second region (228H) that is different than the first region (228I). The optical pipe (228) homogenizing the first light (234A) and the second light (236A). Additionally, the light source assembly (212) can include a third light source (238) that generates a third light (238A) that is directed into the optical pipe (228) at a third region (228G) that is different than the first region (228I) and the second region (228H).

    摘要: A C-plate compensator is disclosed for compensating the residual A-plate and C-plate retardance of a reflective liquid crystal on silicon (LCoS) display or a transmissive liquid crystal (LC) display in a projection display system. The C-plate incorporates a form-birefringent coating, whose retardance magnitude can be adjusted by tilting with respect to the display panel (X-Y) plane. The tilted plate is rotated about the Z-axis by a prescribed amount from the slow axis of the display panel. Criteria are described for choosing the tilt and rotation angles such that the contrast of the display system produced by the compensated panel is optimized.

    摘要: A light source assembly comprises: a light pipe and one or more tapered light collectors operative to reduce the angular distribution of light entering the light pipe from light sources at one or more ports. Dichroic filters and angle-dependent, wavelength selective pass filters control light flow into and through the light pipe. The tapered light collector is operative to reduce the angular distribution of light entering the light pipe. At least a first dichroic filter positioned in the light pipe optically between first and second light entrances is operative to pass first color light from the first light source toward the light port, and to reflect second color light from the second light source toward the light port.
