Leslie G. Butler 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).

  • High energy grating techniques
    Patent number: 10117629
    Abstract: Imaging techniques that may be used in applications such as differential phase contrast imaging are disclosed that include, for example, configuring a beam source and a beam detector such that a beam connects the two, positioning an object, a phase grating and an analyzer grating in the beam path, producing multiple data sets based on various analyzer grating positions, and conducting a regression analysis using a predetermined function having a set of fitting coefficients to establish those fitting coefficients. In those techniques, the fitting coefficients may be used to characterize a set of interference properties associated with the object.
