Patents by Inventor Jane Sprigg

Jane Sprigg has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Non-classical imaging
    Patent number: 11085870
    Abstract: Intensity values of electromagnetic radiation from an object to be imaged are received from an array of detectors. The array of detectors includes one or more pairs of detectors arranged as antisymmetric pairs of detectors. A Fourier transform of an image of the object is determined by correlating fluctuations of the intensity values for each antisymmetric pair of detectors. An inverse of the Fourier transform is determined, and an image of the object is generated from the inverse Fourier transform. The Fourier transform of the mean intensity pattern across the array of detectors may also be used to determine when the array is properly oriented to separate the image and mirror image.
    Type: Grant
    Filed: May 17, 2019
    Date of Patent: August 10, 2021
    Assignees: Northrop Grumman Systems Corporation, Tarsier Optics, Inc.
