Abstract: Presented here are devices and methods to correct ambient light measurements made in the presence of optical elements, such as the curved edge of the cover glass associated with the mobile device. In one embodiment, a film with optical properties is placed within the ambient light sensor to diffuse the high-intensity light beam coming from the optical element. In another embodiment, an aperture associated with the ambient light sensor is disposed to prevent the high-intensity light beam from entering the ambient light sensor. In another embodiment, a processor coupled to the ambient light sensor smoothes the peak associated with the high intensity light beam produced by the optical element.

Abstract: The invention relates to a UV light sensor produced in a CMOS method, comprising a substrate that has a surface, one or more sensor elements that detect radiation and are designed in said substrate, at least one passivation layer arranged over said substrate surface, and a functional layer that is arranged over said passivation layer and designed in the form of at least one filter. The problem addressed by the invention of providing a UV light sensor which is sensitive exclusively within the UV wavelength range is solved, in terms of arrangement, by means of filters designed directly on a planar passivation layer, and stray light suppressing means around said at least one sensor element and/or around the UV light sensor. In terms of the method, the problem is solved by measuring two output signal from at least two photo diodes fitted with different filters, and by determining a mathematical relationship between the two output signals.

Abstract: An infrared detector system is provided for detecting infrared radiation from an infrared radiation source or a scene. The system includes a first area that is semiconductor-based and biased to produce negative luminescence, the first area including at least one semiconductor-based detector. The detector system further includes at least one additional area being semiconductor-based and biased to produce negative luminescence. A low-emissivity specular retro-reflector shield is configured to reflect infrared radiation and covers the first area and the at least one additional area. The shield defines an aperture to allow the at least one semiconductor-based detector to receive incident rays of the infrared radiation from the infrared radiation source or the scene via a low-scatter, low-emission optical system such that the radiation incident from the infrared radiation source or scene substantially fills the solid angle defined by the aperture at any point in the first area.

Abstract: A light source includes a light generating chamber and a collector disposed in the light generating chamber. A target material generator configured to propel a quantity of target material toward an irradiation region is disposed in front of a reflective surface of the collector. A plurality of photodetector modules is disposed external to the light generating chamber, with each of the photodetector modules being directed toward the irradiation region. A plurality of tubes is disposed between a corresponding photodetector module and the irradiation region. Each tube has a centerline directed toward the irradiation region, and each tube has a roughened inner surface. The surface roughness of the roughened inner surface is sufficient to cause grazing incidences of light to be eliminated rather than to be reflected off the roughened inner surface. A method of generating light and a method of measuring light energy also are described.
