摘要： A method is provided for reconstructing an image transmitted through a thick distorting medium. A remote source provides coherent light at the object plane, and a local source, typically derived from the remote source, provides corresponding light that is coherent with respect to the remote source. Light from the remote source is directed through the thick aberrator and into a holographic medium, such as a photorefractive crystal, to interact with corresponding light from the local source and produce a volume hologram. An angularly multiplexed volume hologram, which covers the entire object field, is written into the holographic medium by successive exposures of light from the remote and local sources for successive pixels of the object plane. Light from an object, which comprises two-dimensional information from the object plane, can be reconstructed by the volume hologram after being distorted by the thick aberrator. Light from each point of the object accesses the set of gratings in the volume hologram and reconstructs only the reference wave associated with it. Reconstructed waves emerging from the hologram are then focused by a following lens to form a high resolution image of the object at the image plane of the lens.

摘要： This disclosure provides systems, methods, and devices for actuating, charging and calibrating the charge on a movable electrode in electromechanical systems (EMS) devices. The electromechanical systems device can include a first electrode, a second electrode spaced apart from the first electrode by a gap, a complementary electrode, at least one electrical contact, and a movable third electrode disposed between the first electrode and the second electrode. In one implementation, a method of calibrating charge on the movable electrode of the EMS device includes electrically connecting a complementary electrode to the first electrode to form a compound electrode and applying a calibration voltage across the compound electrode and the second electrode to produce a uniform electric field in the gap. Under the electric field the third electrode moves towards the first electrode until it connects with the at least one electrical contact. Once in contact with the electrical contact, an electrical charge on the third electrode can be changed and calibrated when the third electrode is in a second position. When a mechanical restorative force on the third electrode exceeds the electric force of the uniform electric field on the third electrode, the third electrode then moves to a third position.

摘要： A low power microfabricated atomic clock generates a Coherent Population Trapping resonance. An absorption cell is disposed within a resonator cavity of a Fabry-Perot (FP) resonator or an optical ring resonator to enhance a modulation term of a transmittance. A modulated laser source, external to the resonator, is configured to excite the resonator and the absorption cell with a laser beam passing therethrough. A detector then determines a frequency associated with the CPT resonance of laser light exiting the resonator, and a frequency controller is coupled to the detector to adjust the modulated laser source based on the determined frequency. First and second quarter wave plates are positioned adjacent to respective first and second sides of the resonator.

摘要： In one example, an apparatus includes a processor configured to extract a first set of one or more keypoints from a first set of blurred images of a first octave of a received image, calculate a first set of one or more descriptors for the first set of keypoints, receive a confidence value for a result produced by querying a feature descriptor database with the first set of descriptors, wherein the result comprises information describing an identity of an object in the received image, and extract a second set of one or more keypoints from a second set of blurred images of a second octave of the received image when the confidence value does not exceed a confidence threshold. In this manner, the processor may perform incremental feature descriptor extraction, which may improve computational efficiency of object recognition in digital images.
