Differential Phase Contrast (DPC) X-ray imaging measures both absorption and index of refraction of materials being imaged. This technique has several advantages compared to traditional absorption-only X-ray imaging.
Stanford researchers have developed an exceptionally fast, sensitive, and compact X-ray imaging system for distinguishing liquids and other materials in aviation security applications.
Stanford researchers have invented a C-Aperture Nano-Tip which provides a new way to further enhance the optical resolution down to smaller than 15 nm.
Stanford researchers have designed a method to increase the photoyield of thin film CsBr/metal photocathodes by activation with electron bombardment, allowing efficient operation at UV and longer incident light wavelengths.
Researchers in Prof. Lambertus Hesselink's laboratory have developed a compact, sensitive X-ray differential phase contrast (DPC) imaging system that improves field of view, increases fringe visibility and shortens imaging times.
