Patent application number | Description | Published |
20090073451 | Spectrally diverse, spatially sensitive apparatus and associated methods - A spectrometer for use with a desired wavelength range includes an array of filters. Each filter outputs at least two non-contiguous wavelength peaks within the desired wavelength range. The array of filters is spectrally diverse over the desired wavelength range, and each filter in the array of filters outputs a spectrum of a first resolution. An array of detectors has a detector for receiving an output of a corresponding filter. A processor receives signals from each detector, and outputs a reconstructed spectrum having a second resolution, the second resolution being higher than any of the first resolution of each filter. Filters and detectors may be arranged into a plurality of imaging units, each imaging unit including first and second filters and first and second photosensing regions. A processor receives signals from each imaging unit, and generates a reconstructed spatial image comprised of discrete spatial units corresponding to each imaging unit. | 03-19-2009 |
20090290833 | Optical device including at least one replicated surface and associated methods - An optical device includes a substrate. a non-planar transparent structure on a first surface of the substrate, the non-planar transparent structure being made of a first material, and a molded refractive surface on the first surface of the substrate adjacent the non-planar transparent structure, the molded refractive surface being made of a second material, different from the first material. | 11-26-2009 |
20100321564 | Camera system and associated methods - A camera system may include an optics stack including two substrates, the optics stack forming an imaging system, each substrate having two surfaces that are parallel to each other and perpendicular to an optical axis of the imaging system, the optics stack including a securing region on opposing surfaces of the two substrates, the two substrates being secured together on a wafer level at their respective securing regions, at least one of the surfaces of the two substrates including a refractive surface of the imaging system, a detector substrate having an active area and a cover structure protecting at least the active area of the detector substrate, the optics stack being secured to an upper surface of the cover structure. | 12-23-2010 |
20110068258 | NONROTATIONALLY SYMMETRIC LENS, IMAGING SYSTEM INCLUDING THE SAME, AND ASSOCIATED METHODS - A singlet lens with opposing first and second surfaces has at least one surface being nonrotationally symmetric, the singlet lens substantially maintaining a ratio of magnification along orthogonal axes. The nonrotationally symmetric surface may be used in an imaging system, which may be used in a mobile handset. | 03-24-2011 |
20120076456 | Optical element and system using the same - A method for transmitting a signal in an optical system includes generating an optical signal along an optical axis for transmission through an optical element, positioning the optical element so that a surface discontinuity is positioned along the optical axis such that the optical signal defines a substantially radially symmetric intensity profile, and launching the optical signal into an input face of an optical fiber such that the intensity profile is substantially null proximate an optical axis associated with the optical fiber. | 03-29-2012 |
