Shrink rays may exist only in science fiction, but similar effects are at work in the real world at the National Institute of Standards and Technology (NIST). After successfully miniaturizing both ...

Researchers have demonstrated a compact atomic gyroscope design that could, with further development, be portable, low power, and accurate enough to be used for navigation. Shrink rays may exist only ...

After successfully miniaturizing both clocks and magnetometers based on the properties of individual atoms, NIST physicists have now turned to precision gyroscopes, which measure rotation. NIST’s ...

Optical gyroscopes are widely used in vehicle navigation. They use laser beams in a fibre-optic loop, and the beams produce interference when the device's orientation changes. Optical devices are more ...
