The current state of the art of embedded motion sensing is based around micro-electromechanical systems (MEMS) devices. These miracles of microfabrication use tiny silicon structures, configured to ...

Interferences in ordinary space are easier to understand than those of the abstract space of quantum states, so it is illuminating to make the analogy between the Ramsey design 20 and a standard ...

Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices. This requires the development of ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

What's on and in a star? What happens in an active galactic nucleus? Answering those questions is the goal of a proposed giant interferometer on the moon. It's called the Artemis-enabled Stellar ...

A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

NASA has selected a new mission to study how the Sun generates and releases giant space weather storms – known as solar particle storms – into planetary space. Not only will such information improve ...

Inconceivable, but true: if you want to detect gravitational waves one day using an installation such as GEO600, you must measure the mutual shift of two light waves by a hundred billionth of a degree ...

An interferometer sounds like something complicated, and in a way, it is. But it is also pretty easy to build one with some common materials. [Let’s Innovate] has instructions for how to make an ...
