Now, researchers from the California Institute of Technology are developing a laser-based accelerometer, that they claim should offer much better performance than is currently possible.

In fact, because the instrument uses laser light of a known frequency to measure acceleration, it may ultimately serve as a portable reference standard to calibrate other accelerometers now on the ...

A laser pulse is fired at the atom that puts it in a superposition ... Such a device can also be used as an extremely sensitive vertical accelerometer. Now, Ed Hinds and colleagues at Imperial College ...

Miniature accelerometers are already common (most mobile phones, for example, contain one), but these are mechanical rather than laser-based devices. Their job is inertial navigation, which ...

“A quantum accelerometer will reduce that to just ... state that is easily perturbed by an outside force – and another laser beam can then be used to track them. This looks out for any changes ...
