X-ray astronomy is a somewhat neglected corner of the more general field of astronomy. The biggest names in telescopes, like ...

This technique can be defined as a “frame rate” limited method. The Twyman-Green interferometers offered by 4D Technology use a completely different method. Using a polarization-based Dynamic ...

Image Credit: 4D Technology. Phase-Shifting Interferometers are Limited by Vibration and Turbulence In phase-shifting interferometers, time elapses while acquiring the measurement data, and this ...

They can detect extremely weak magnetic fields, making them valuable tools for applications such as brain imaging, geophysical surveys, and quantum computing. Atomic interferometers use the ...
