By combining the unique strengths of tabletop, coherent, EUV high-harmonic sources with excellent phase stability and CDI, we can address imaging science challenges associated with the synthesis and integration of next-generation quantum, semiconductor, and spintronic devices and heterostructures, independent of architecture.

2018年11月12日 · In this study, we report on a newly established high photon flux and highly monochromatic 30 nm HHG beamline. Furthermore, we applied ptychography, a scanning CDI version, to probe a nearly...

Coherent diffractive imaging (CDI) is a lensless imaging technique that pro-vides both amplitude and phase infor-mation about the sample – enabling both topographical and chemical data to be determined. EUV light generated from lasers is tunable, much like synchrotron radia-tion.

Coherent diffractive imaging (CDI) using ultra-short wavelength light source has become an three-dimensional(3D) nanoimaging technique. In CDI, a target sample is first illuminated by a coherent EUV and soft X-ray light, then the diffraction pattern is recorded by using a charge coupled device (CCD), and finally the image of the sample is ...

2015年9月8日 · Here we demonstrate sparsity-based coherent diffraction imaging of 1D objects using extreme-ultraviolet radiation produced from high harmonic generation. Using sparsity as prior information removes...

EUV CDI provides a unique capability for quantitative, chemically-speci c imaging of buried structures. This will make possible unprecedented studies of material evo-lution at buried interfaces, compared with all other ap-proaches. In the future, the fast temporal resolution of high harmonics can be harnessed for imaging dynamically

2015年11月1日 · Coherent diffractive imaging (CDI) is an important new full field imaging technique that can achieve very high spatial and temporal resolution simultaneously. In CDI, a spatially coherent beam illuminates an object, and the intensity of the scattered light is then collected on a pixel array detector.

2013年9月23日 · By implementing keyhole coherent diffractive imaging with curved mirrors and a tabletop high harmonic source, we achieve improved efficiency of the imaging system as well as more uniform...

ultraviolet (EUV) sources, we demonstrate coherent diffraction imaging (CDI) with relative bandwidth of ≈20%. The coherence properties of the illumination probe are identified using the same imaging setup. The presented methods allow us to use fewer monochromating optics, obtaining higher flux

2015年12月1日 · We report the demonstration of a scanning probe coherent diffractive imaging method (also known as ptychographic CDI) using a compact and partially coherent gas-discharge plasma source of extreme ultraviolet (EUV) radiation at a 17.3 nm wavelength.
