  • Publication number: 20120274811
    Abstract: Electronic devices may include array cameras having lens arrays, an corresponding color filter arrays, and corresponding image sensor arrays. Lenses in lens arrays may be aligned with positions on associated image sensors other than the centers of the associated image sensors. Lens arrays may include one or more layers of lenses formed by compression molding of transparent materials such as plastic. Lens arrays may be mounted directly onto integrated circuit dies on which the image sensor arrays are formed. Color filter arrays may include one or more red filters, one or more green filters and one or more blue filters. Offsetting the centers of lenses with respect to the centers of associated image sensors may allow capture of spatially offset single-color images by the image sensors. Spatially offset single-color images may be combined into super-resolution images using the processing circuitry.

  • Publication number: 20120045103
    Abstract: An image sensor integrated circuit may contain image sensor pixels. A channel containing a fluid with particles such as cells may be formed on top of the image sensor. Some of the image sensor pixels may form a calibration sensor and some of the image sensor pixels may form an imager. As the fluid and particles flow through the channel at a flow rate, the calibration sensor may measures the flow rate and illumination intensity in the channel. Based on calibration data such as measured flow rate and measured illumination intensity, adjustments may be made to ensure that the imager acquires satisfactory image data. The adjustments may include flow rate adjustments, image acquisition data rate adjustments, and illumination adjustments. A processing unit in the channel may contain a laser or other component to destroy selected cells. A flared region in the channel may be used as a chromatograph.

  • Publication number: 20120044339
    Abstract: An image sensor integrated circuit may contain image sensor pixels. A channel containing a fluid with particles such as cells may be formed on top of the image sensor. The image sensor pixels may form light sensors and imagers. The imagers may gather images of the cells or other particles as the fluid passes over the imagers. The channel may have multiple branches. Gating structures and other fluid control structures may control the flow of fluid through the channel branches. Portions of the channel may be used to form chambers. The chambers may each be provided with one or more light sensors, light sources, and color filters to alter the color of illumination form a light source, one or more reactants such as dyes, antigens, and antibodies, and heaters. The branches may route the fluid to respective chambers each of which has a different set of capabilities.

  • Patent number: 7991240
    Abstract: Methods, systems and apparatuses for modeling high resolution images which significantly shortens computation time and reduces image artifacts, as compared to known methods. Embodiments implement a look-up table, to compute once and store the point spread functions for various points of an image. During modeling of the optical system, previously stored point spread functions may be used to determine the point spread function for a specified point using a weighted interpolation of the point spread functions that have been stored for nearby points.

  • Publication number: 20060238545
    Abstract: A display device (10) having pixels elements (118) divided into subpixel zones (131), so that each subpixel zone is associated to a predetermined viewing direction (160, 162, and 164). The light outputs of subpixel zones are controlled by an array of scanning focused electron beams (82). Each electron beam corresponds to a different pixel. The subpixel zones of the pixel are activated by electron beam in accordance with the input data signal (280). An array of microlenses (120) is provided in front of the pixels, so that each column of microlenses corresponds to a different column of pixels. The microlens projects the light outputs of the subpixel zones of the corresponding pixel into observation directions (170, 204) creating direction-dependent view of the pixel. The thin-panel display device is capable generating high-resolution real-like 3D images of scenes, objects, and models. Observers do not require wearing any special devices or glasses.

  • Publication number: 20050105103
    Abstract: A characteristic of a surface is measured by illuminating the surface with optical radiation over a wide angle and receiving radiation reflected from the surface over an angle that depends on the extend of the illumination angle. An emissivity measurement is made for the surface, and, alternatively, if a reflectivity measurement is made, it becomes more accurate. One application is to measure the thickness of a layer or layers, either a layer made of transparent material or a metal layer. A one or multiple wavelength technique allow very precise measurements of layer thickness. Noise from ambient radiation is minimized by modulating the radiation source at a frequency where such noise is a minimum or non-existent. The measurements may be made during processing of the surface in order to allow precise control of processing semiconductor wafers, flat panel displays, or other articles. A principal application is in situ monitoring of film thickness reduction by chemical-mechanical-polishing (CMP).

  • Publication number: 20050024736
    Abstract: In the beam path of an Optical Cross Connect between the front face of a fiber block and a moveable mirror array are placed a telecentric lens and multi-surface optical element. The lens is placed adjacent the front face with a front focal plane coinciding with the front face. The substantially parallel beam path axes between the front face and the telecentric lens are converted by the lens into dispersing directions towards the optical element. Discrete optical surfaces of the optical element redirect the dispersing beam paths in a fashion such that the beam paths coincide in the following with corresponding moveable mirrors of a mirror array. Pitches of arrayed fiber ends and of the optical surfaces as well as the moveable mirrors are independently selectable. The telecentric lens simultaneously focuses the signal beams with improved beam separation and reduced signal loss.
