  • Patent number: 11251952
    Abstract: Systems and methods for quantum clock synchronization are provided. Various embodiments can use time-energy and polarization entangled photons to securely extract the absolute time difference between two remote clocks. In some embodiments, two parties can each have a source of entangled photons. Each party can detect one member of the pair locally and time stamp the detection time, while the other photon gets sent over a common channel (single optical mode) to the other party where the transmitted photon is detected and time stamped. The time stamp values can be shared over an open authenticated channel and each receiver can run a cross-correlation of the detection times. The authenticity and non-spoofability of the timing signal are ensured if each party does not just perform a simple time of arrival measurement but also incorporate polarization measurements whose joint values constitute a Bell test.

  • Patent number: 10533957
    Abstract: First ROI pixel values of a first region of interest 101 of a radiographic intensity distribution image 10, and second ROI pixel values of a second region of interest 102 of the radiographic intensity distribution image 10, are acquired. One of the first and second regions of interest is set to be at a position, or vicinity thereof, where a phase difference in the intensity modulation period within the radiographic intensity distribution image, with respect to the other region of interest, becomes ?/2. Next, an elliptical locus obtained by plotting the first and second ROI pixel values for each radiographic intensity distribution image is determined. k angle region images are then acquired using the radiographic intensity distribution images corresponding to at least k angle regions that have been obtained by dividing the elliptical locus for each given angle. A radiographic image is then generated using the k angle region images. k is an integer of three or more.

  • Patent number: 10423002
    Abstract: The cost and power consumption of an imaging apparatus are reduced by facilitating detection of an incident angle of a light beam transmitted through a grating substrate. An image sensor converts an optical image captured by pixels arranged on an imaging surface and outputs the converted image signal. A modulator is configured to modulate intensity of light; and an image processing circuit performs image processing of the output image signal. The modulator has a grating substrate, a grating pattern formed on a back surface side of the grating substrate arranged in proximity to the light receiving surface of the image sensor; and a grating pattern formed on a front surface facing the back surface. Each of the grating patterns is constituted of concentric circles. The modulator performs intensity modulation on the light transmitted through the grating pattern and outputs the modulated light to the image sensor.

  • Patent number: 10389953
    Abstract: A shutter assembly may be provided for an infrared imaging module to selectively block external infrared radiation from reaching infrared sensors of the infrared imaging module. For example, the shutter assembly may comprise a paddle situated external to an optical element (e.g., lens) and adapted to be selectively moved by an actuator to substantially block external infrared radiation from entering the optical element. The shutter assembly may be stacked relative to a housing of the infrared imaging module without excessively increasing the overall profile of the infrared imaging module. A substantially reflective low emissivity interior surface may be provided on the paddle to reflect infrared radiation originating from an infrared sensor assembly of the infrared imaging module back to the infrared sensor assembly.
