Abstract: An integrated circuit that includes a substrate, a photodiode, and a Fresnel structure. The photodiode is formed on the substrate, and it has a p-n junction. The Fresnel structure is formed above the photodiode, and it defines a focal zone that is positioned within a proximity of the p-n junction. In one aspect, the Fresnel structure may include a trench pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In another aspect, the Fresnel structure may include a wiring pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In yet another aspect, the Fresnel structure may include a transparent dielectric pattern that functions as a refractive means for redirecting and concentrating incident photons to the focal zone.

Abstract: An imaging system includes an imager housing having a primary aperture defining an optical axis. A primary lens is disposed over the primary aperture. A first focal plane array (FPA) is within the imager housing. A second FPA is within the imager housing. A digital micro-mirror device (DMD) is angled with respect to the optical axis and optically coupled to the primary lens to selectively reflect light entering the primary aperture to at least one of the first FPA or the second FPA.

Abstract: An electronic device may be provided with light sensors. The electronic device may have an electronic device housing in which a display is mounted. The display may have a transparent layer such as a transparent display cover layer, a thin-film transistor layer, or a color filter layer. An opaque masking layer such as a layer of black ink may be used to cover an inner surface of the transparent layer in an inactive area of the display. Sensor window openings may be formed in the black ink layer. A layer of ink may be formed in each sensor window opening. Each layer of ink may have a diffuse reflectivity that is matched to that of the black ink. A diffuser layer such as a polymer coating layer with light-scattering particles may be coated on the inner surface of the layer of ink in a sensor window opening.

Abstract: A passive infrared motion detection sensor that includes a Fresnel focusing arrangement that creates at least a first infrared sensing region, a second infrared sensing region, and a third infrared sensing region, in which target detection in one or more infrared sensing regions is weighted to be distinguishable from target detection in remaining infrared sensing regions. The Fresnel focusing arrangement creates the weighted infrared sensing regions using a lenslet region, an optically opaque region and a plurality of extruded cylindrical lenslets that extend across a portion of both the lenslet region and the optically opaque region. The signal detection in at least the second weighted infrared sensing region, for example, an infrared sensing range between 6 and 10 feet, is weighted to easily distinguish between a pet within the second infrared sensing range and a person at any infrared sensing range.
