  • X-ray microscope with switchable x-ray source
    Patent number: 7813475
    Abstract: An x-ray imaging system uses a synchrotron radiation beam to acquire x-ray images and at least one integrated x-ray source. The system has an imaging system including sample stage controlled by linear translation stages, objective x-ray lens, and x-ray sensitive detector system, placed on a fixed optical table and a mechanical translation stage system to switch x-ray sources when synchrotron radiation beam is not available.
    Type: Grant
    Filed: March 11, 2009
    Date of Patent: October 12, 2010
    Assignee: Xradia, Inc.
    Inventors: Ziyu Wu, Wenbing Yun, Peiping Zhu, Yuxin Wang, Qingxi Yuan, Andrei Tkachuk, Wanxia Huang, Michael Feser
