摘要： An optical assembly for reducing the etendue of a diode laser light source having a plurality of laser light emitters. The optical assembly comprises a first optical device for collimating beams of light emitted from the emitters of the diode laser. A second optical device spatially shifts a portion of the collimated light beams emitted from the diode laser to thereby reduce gaps or dark space between the beams. A third optical device focuses all of the light beams onto a surface, such as a surface of a light modulation surface.

摘要： The invention provides a system and method for reducing laser speckle and interference patterns in a laser projector display when using a laser projector having a spatial light modulator (SLM) with a defined pixel rate. The method can include the operation of polarizing a laser output 104 of a continuous wave laser 102 such that the laser output is s-polarized with respect to a beam combiner 140. The s-polarized laser output 108 can be divided into a first laser beam 112 and a second laser beam 116. A phase of the second laser beam 116 can be modulated with an amplitude sufficient to create a phase delay of approximately half a wavelength of the laser output 104 and at a frequency at least twice that of the SLM' s pixel rate.

摘要： To create a dynamic textured display, images of textured height fields (elevation samples arrayed on a rectangular coordinate grid, as to represent a terrain) are rendered, the system performing an initial pass that resamples the height-field data into a radial form and a subsequent pass using the radial data to create textured, shaded picture elements (pixels) for an instantaneous field of view. Thus, texturing, shading, blending and scan conversion complete the pixel processing to drive a display unit. The system is particularly applicable to the generation of dynamic perspective images of terrain. The process provides pixel-limited textural resolution in the final image with effective antialiasing of internal and horizontal silhouette edges.

摘要： A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.

摘要： A panoramic display system (10’) includes a curved projection screen (14’), a panoramic projector (12’), and a substantially conically shaped barrier (218). The projector (12’) is configured to project an image onto the projection screen (14’) from a projection point located substantially above the projection screen.
