Deep-reactive-ion-etching in X-ray grating fabrication: a review

September 8, 2025
Author(s)
Daniel Josell, Zhitian Shi, Konstantins Jefimovs, Joan Vial Comamala, Alexandre Pereira, Marco Stampanoni, Lucia Romano
The development of grating fabrication shares its journey with the development of X-ray phase contrast imaging. Indeed, the fabrication of gratings with features of sufficiently high aspect ratio is one of the bottlenecks preventing the widespread

Calibrating laser Doppler anemometers utilizing an optical chopper

January 31, 2025
Author(s)
Christopher Crowley, Iosif Isaakovich Shinder, Michael R. Moldover, Joey Boyd, James Filla, Aaron Johnson
Laser Doppler anemometers (LDAs) use scattered light to determine velocity components of a flowing fluid. The operating principal of LDAs is simple conceptually; however, it is impractical to trace the LDA-determined velocities to the SI by characterizing
