Abstract: In described examples, a projector includes a light source to produce first light of a first color. The projector also includes a phosphor to selectively receive the first light and produce second light of a second color in response to the first light. The projector also includes a dichroic mirror to pass a portion of the second light to produce a third light of a third color. The dichroic mirror reflects a portion of the second light as fourth light of a fourth color.

Abstract: Described examples include a projection system having projection optics with a projection optics axis tilted from an axis perpendicular to an image target, the projection optics configured to project an image. The projection system also having an image source, the image source configured to provide the image, the image source having an offset from the projection optics axis, a plane of the image source having an angle from perpendicular to the projection optics axis such that a projected image from the image source projected by the projection optics is focused onto the image target along an extent of the projected image.

Abstract: In described examples, a method of creating multiple light images uses spatially-separated light sources, arranged in an array, operated in multiplexed fashion, for driving a spatial light modulator. Each of the light sources is time-sequenced to direct light at the spatial light modulator during a predetermined time interval. The spatial light modulator is synchronized with the light sources and controlled to produce a desired image during each time interval. The resulting images are received by an optical lens system to provide light images along an image plane. Alternately, the optical lens system focuses the modulated light images on a hogel plane to produce a light field. The pixel count of the spatial light modulator is effectively multiplied by the number of light sources. Each light source may sequentially provide multiple colors to produce a full-color image. The light source array may, in turn, be driven by one or more remotely-located master light sources.

Abstract: Apparatus and methods are described for creating multiple different heads-up display (HUD) images at different apparent distances from a viewer using a single picture generator. First and second images are generated using respective first and second subsets of modulating elements of an array of image pixel modulating elements of a spatial light modulator. Light from the first and second images is directed along respective first and second optical paths onto a transparent display surface to form respective first and second virtual images at different apparent distances within a field of view of a viewer looking through the display surface. In a described example, the modulating elements are micromirrors of a digital micromirror device (DMD) and optical elements of the respective optical paths are relatively movable to set relative path lengths.
