X-ray imaging commonly relies on the attenuation contrast, in which the visibility of internal structures arises from different levels of radiation absorption. In comparison, phase-contrast imaging, ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2024.230034 discusses how the synergy of traditional techniques and deep learning enables single-frame high-precision fringe pattern ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Researchers at the University of Stuttgart, Germany, have developed a waveguide interferometer that uses multimodal light to measure changes in distance or motion. Yuri Ovchinnikov and Tilman Pfau ...
