Abstract: An illumination source and a method therefor. A light source includes a light circuit configured to process light and direct light, and a lighting element optically coupled to the light circuit to provide multiple colors of light. The light circuit propagates light using light guides. The use of light guides eliminates the use of free space optical elements, enabling the creation of more compact light sources. Furthermore, the use of light guides may enable the creation of light sources with fewer mechanical restrictions, thereby making the light sources potentially more reliable and less expensive.

Abstract: Improvement of speckling noise is discussed in which a central light beam received at a double-sided mirror is divided into a plurality of sub-beams. An intensity of these sub-beams decays from a second sub-beam to a last sub-beam of the plurality. Each sub-beam is also separated at the double-sided mirror by at least a first length, such as the coherence length or intrinsic divergence, and reflected toward a display screen. The configuration of the double-sided mirror focuses the sub-beams to converge with a first sub-beam on the display screen at different angles. The decreasing intensity and different angles of impact with the screen decreases the spatial coherence of the display light. The angle diversity and combination of multiple sub-beams having different intensities offers a non-time-averaging means to decrease speckle noise without downgrading the beam quality or display resolution.

Abstract: System and method for increasing display brightness in laser illuminated display systems. An illumination source includes a light source to produce light, a disk having a set of lens elements arranged in a circular ring around a center of the disk, a motor coupled to the disk, and an external lens positioned in a light path of the coherent light source. As the disk rotates, the lens elements are moved sequentially through the light, angularly deflecting the light, which may be corrected by the external lens into a spatial deflection. The spatially deflected light may be used to simultaneously illuminate a surface with more than one color of light, thereby increasing the brightness of the light source.
