Patent number: 10859517Abstract: Single X-ray grating differential phase contrast (DPC) X-ray imaging is provided by replacing the conventional X-ray source with a photo-emitter X-ray source array (PeXSA), and by replacing the conventional X-ray detector with a photonic-channeled X-ray detector array (PcXDA). These substitutions allow for the elimination of the G0 and G2 amplitude X-ray gratings used in conventional DPC X-ray imaging. Equivalent spatial patterns are formed optically in the PeXSA and the PcXDA. The result is DPC imaging that only has a single X-ray grating (i.e., the G1 X-ray phase grating).Type: GrantFiled: June 30, 2017Date of Patent: December 8, 2020Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Lambertus Hesselink, Max Yuen, Yao-Te Cheng, Yuzuru Takashima

Patent number: 8196217Abstract: Transmission efficiency and/or spatial resolution provided by resonant apertures can be enhanced by disposing a tip on part of the screen that extends laterally into the aperture. For example, a tip disposed on the ridge of a C-shaped aperture can dramatically improve performance. A spatial resolution of ?/50 has been experimentally demonstrated with this approach. The combination of high spatial resolution and high transmission efficiency provided by this approach enables many applications, such as near field optical probes for near field scanning optical microscopy (NSOM). Another application is high resolution electron sources, where an photoelectron emitter can be disposed at or near a tip+aperture structure such that the high resolution optical near-field provides a correspondingly high resolution electron source.Type: GrantFiled: August 16, 2010Date of Patent: June 5, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Yao-Te Cheng, Yin Yuen, Paul C.
