But there’s a problem. While it’s a simple matter to build mirrors and beam splitters for photons, it’s extremely difficult to do that for matter waves. As a result, matter-wave interferometers are ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...

Circular thinking: light a ring laser has been used to measure the Earth’s rotation. (Courtesy: iStock/amtitus) A gyroscope sensitive enough to detect Earth’s rotation has been created using a ...

A gyroscope is any rotating body that exhibits two properties: gyroscopic inertia or rigidity in space and precession or the tilting of the axis at right angles to any force tending to alter the plane ...

The modern smartphone is only possible because of sensors. Their svelte form factor conceals accelerometers, magnetometers, temperature sensors, a GPS unit, and gyroscopes. They all consume volume and ...
