  • Patent number: 8779483
    Abstract: Electronic devices may be provided with imaging modules that include plasmonic light collectors. Plasmonic light collectors may be configured to exploit an interaction between incoming light and plasmons in the plasmonic light collector to alter the path of the incoming light. Plasmonic light collectors may include one or more spectrally tuned plasmonic image pixels configured to preferentially trap light of a given frequency. Spectrally tuned plasmonic image pixels may include plasmonic structures formed form a patterned metal layer over doped silicon layers. Doped silicon layers may be interposed between plasmonic structures and a reflective layer. Plasmonic image pixels may be used to absorb and detect as much as, or more than, ninety percent of incident light at wavelengths ranging from the infrared to the ultraviolet. Plasmonic image pixels that capture light of different colors may be arranged in patterned arrays to form imager modules or imaging spectrometers for optofluidic microscopes.

  • Patent number: 8780086
    Abstract: A light-based input device may be based on a wedge-shaped light-guide structure. Light may be introduced into the interior of the light-guide structure from a light source and corresponding reflected light exiting the light-guide structure may be measured using a light detector such as an image sensor. The location at which a user places an object in contact with an upper surface of the light-guide structure may be detected by analyzing the pattern of reflected light that exits the light-guide structure. Multiple layers of light-guide structures may be separated from each other by opaque material such as plastic so that the device can determine the direction in which the object is traversing the light-guide layers. A light-based input device may be implemented using free-space light beams that are interrupted by the user. Keys may be provided in a light-based input device by movably mounting contact pads to a light-guide structure.

  • Patent number: 8749525
    Abstract: A light-based input device may have multiple branches each based on a respective light-guide structure. A light source may launch light into the light-guide structures. A light sensor may detect light reflected from the light-guide structures or transmitted through the light-guide structures. The light-based input device may be used to gather user input from a user of an electronic device. The user may move an object into contact with the light-guide structures. The light sensor may monitor light intensity fluctuations from the light-guide structures to determine where the light-guide structures have been contacted by the object. Multiple wavelengths of light may be used by the light source and light sensor to reduce crosstalk between adjacent branches of the light-based input device.

  • Patent number: 8680455
    Abstract: An electronic device may be provided with imaging modules or communications modules. Imaging modules and communications modules may be improved with the use of plasmonic light collectors. Plasmonic light collectors exploit the interaction between incoming light and plasmons in the plasmonic light collector to redirect the path of the incoming light. Plasmonic light collectors may be used to form lenses for image pixels in an imaging module or to form light pipes or lenses for use in injecting optical communications into a fiber optic cable. Plasmonic lenses may be formed by lithography of metallic surfaces, by implantation or by stacking and patterning of layers of materials having different dielectric properties. Plasmonic image pixels may be smaller and more efficient than conventional image pixels. Plasmonic light guides may have significantly less signal loss than conventional lenses and light guides.

  • Patent number: 8538120
    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: 20130100082
    Abstract: An electronic device may have a touch panel. The touch panel may detect touch events using one or more cameras. The touch panel may include a planar exterior surface, such as a cover glass, that extends over an active region of a display and an inactive peripheral region. The cameras may be located underneath the inactive peripheral region. The cameras may include a light turning element to allow the cameras to detect touch events, without being raised above the exterior surface of the active region of the display (e.g., without having a raised profile). The touch panel may detect touch events using dynamic zooming techniques. As an example, the touch panel may divide the active region into sections, search for touch events in each section, zoom into sections in which touch events are found, and further search the sections in which touch events were found.

  • Publication number: 20130100266
    Abstract: Electronic devices may include imaging systems with camera modules and light sources. A camera module may be used to capture images while operating one or more light sources. Operating the light sources may generate changing illumination patterns on surfaces of objects to be imaged. Images of an object may be captured under one or more different illumination conditions generated using the light sources. Shadow patterns in the captured images may change from one image captured under one illumination condition to another image captured under a different illumination condition. The electronic device may detect changes in the shadow patterns between multiple captured images. The detected changes in shadow patterns may be used to determine whether an object in an image is a planar object or an object having protruding features. A user authentication system in the device may permit or deny access to the device based, in part, on that determination.

  • Publication number: 20130100020
    Abstract: Electronic devices may include touch-free user input components that include camera modules having overlapping fields-of-view. The overlapping fields-of-view may form a gesture tracking volume in which multi-dimensional user gestures can be tracked using images captured with the camera modules. A camera module may include an image sensor having an array of image pixels and a diffractive element that redirects light onto the array of image pixels. The diffractive element may re-orient the field-of-view of each camera module so that an outer edge of the field-of-view runs along an outer surface of a display for the device. The device may include processing circuitry that operates the device using user input data based on the user gestures in the gesture tracking volume. The processing circuitry may operate the display based on the user gestures by displaying regional markers having a size and a location that depend on the user gestures.

  • Publication number: 20130070109
    Abstract: An electronic device may have a camera module. The camera module may include a camera sensor capable of capturing foveated images. The camera sensor may be hardwired to capture foveated images with fixed regions of different quality levels or may be dynamically-reconfigurable to capture foveated images with selected regions of different quality levels. As one example, the camera module may be hardwired to capture a center region of an image at full resolution and peripheral regions at reduced resolutions, so that a user can merely center objects of interest in the image to capture a foveated image. As another example, the camera module may analyze previous images to identify objects of interest and may then reconfigure itself to capture the identified objects of interest at a high quality level, while capturing other regions at reduced quality levels.

  • Publication number: 20120326009
    Abstract: An electronic device may be provided a plasmonic light sensor. Plasmonic light sensors may include arrays of plasmonic image pixels that detect evanescent electron density waves, or plasmons, generated in the plasmonic image pixel through an interaction with incoming light. Plasmonic image pixels may include microlenses that focus the light onto conducting wires in the plasmonic image pixel. Plasmons generated on the surface of the conducting wire may propagate along the conducting wire. Detector circuitry may be coupled to the wire on which the plasmons propagate to detect the light through detection of the evanescent electron density wave. Detector circuitry may include a biasing component for biasing a photodiode such that a small amount of light results in an avalanche of charge, or a sudden increase in current, produced in the detector circuitry in response to the evanescent wave.
