Abstract: Disclosed are a light guide (750) and an electronic device including a light guide for coupling ambient light to a light sensor. The light guide (750) that is a structure of light-transmitting material having an elongate shape including a first end (752) for receiving ambient light and a second end (754) for collecting ambient light to transmit to a light sensor. The first end (752) of the light guide has a concave shape and the second end (754) of the light guide also has a concave shape. An electronic device may support the light guide and a light sensor. The concave shape of the second end of the light sensor may disperse light toward the light sensor, rather than tightly focusing the light toward the light sensor. Accordingly, the light sensor may have a sensing area that forms a detection plane so that the detection plane is positioned adjacent to the second end.

Abstract: An electronic optical zoom system (100) includes a first lens assembly (101) and a second lens assembly (102). The first lens assembly (101) and the second lens assembly (102) may be adjacently disposed or concentrically disposed. The first lens assembly (101) and second lens assembly (102), in one embodiment, have different magnification configurations. An image sensor (103) captures electronic images of a subject (109). Optical zoom capability is achieved by an alterable electronic optical device (851), such as a switchable mirror (105). The alterable electronic optical device (851) selectively redirects received light between a first optical path (107) from a reflective surface (106) to a second optical path (117) from the alterable electronic optical device (851) depending upon the state of the alterable electronic optical device (851). The electronic optical zoom system (100) thereby provides optical zoom capabilities in a compact package without the need for physically moving lens assemblies.

Abstract: The present invention provides a system for reducing the size of a projection display system. This is achieved by using an emissive imager that comprises a large number of emissive pixels. The emissive pixels provide both light output and light modulation functions. This eliminates the need for a separate illumination source. Each emissive pixel represents a pixel (or a sub- pixel for color projection) of an image to be projected. The light signals produced and modulated by the emissive imager are passed through a microlens array. The microlens array collects and reshapes the emitted light signals from the emissive pixels. Each microlens forms a light beam with a concentrated non-Lambertian radiation profile. The non-Lambertian radiation profile helps in effective collection of light at a projection lens. Finally, the projection lens collects this light and projects a magnified image on a projection screen.

Abstract: A projector system comprises an illumination system (104), at least one imager (106, 202, 302), a diffuser (108), and a projection lens (110). The illumination system generates a collimated light (112), which is provided to the imager. The at least one imager modulates the collimated light according to the information required for image formation. The diffuser receives the modulated collimated light (114), and diffuses it into a divergent light (116), thereby relaying the image from the imager to the diffuser. The projection lens projects the divergent light on the projection screen (102).

Abstract: The present invention provides a compact color illumination device (100) for emitting collimated light. The illumination device comprises a reflector cup (102), a blazed diffraction grating (108) formed on the inner surface of the reflector cup, and a plurality of light emitting sources (110) positioned linearly in a focal plane of the reflector cup. Each light emitting source emits a different color of light that is incident on the blazed diffraction grating. The light emitted by the light emitting sources is reflected by the blazed diffraction grating, wherein the reflected light is collimated.
