The present disclosure relates to a flexure mechanism that includes a plurality of thin material structures, each thin material structure including a weak-link portion and a separable constraint portion. The separable constraint portion is linked to the weak-link portion and configured to stabilize the weak-link portion. Additionally, the plurality of thin material structures are stacked and secured together to form a laminar structure.

Constrained flexure mechanism and method for manufacturing the same

Phase contrast and dark-field X-ray imaging enable imaging of objects that absorb or reflect very little X-ray light. Disclosed is a method and systems for performing coded-mask-based multi-contrast imaging (CMMI). The method includes providing radiation to a coded mask that has a known phase and absorption profile according to a pre-determined pattern. The radiation is then impingent upon a sample, and the radiation is detected to perform phase-reconstruction and image processing. The method and associated systems allow for the use of maximum-likelihood and machine learning methods for reconstruction images of the sample from the detected radiation.

Coded-mask-based X-ray phase-contrast and dark-field imaging

Methods and related equipment for dynamic on-axis in-situ interferometry where the reference surface is positioned in an vacuum chamber. The systems use a wavelength shifting, or a phase shifting interferometer that allows the freedom to eliminate the need to step the cavity length physically with the reference surface, allowing the reference surface to be placed inside the vacuum chamber.
