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 ...

With two key product lines in that category, Zygo offers an optical profiler and a laser interferometer as well as producing displacement measuring interferometers as a part of its PPS product line.

However, the new instrument self-corrects for these flaws to achieve record-breaking precision, in contrast to other atom interferometers that are constrained by the faults in the light itself.

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 ...
