Laser gyroscopes are pretty much the "if only" of tiny sensors. Essentially, they seem like they should rule the roost in terms of providing a clean and clear signal.

Ring Laser Gyroscope's small size has also made them particularly well suited for tactical aircraft, both manned and unmanned, and weapon systems that once had to rely on much bulkier inertial ...

Basement ring: the laser gyroscope. (Courtesy: K Ulrich Schreiber et al/Nature Photonics). After 30 years of painstaking development, researchers in Germany and New Zealand have unveiled a laser ...

Now a group of researchers split between New Zealand and Germany have put together a laser gyroscope that is sensitive enough to measure the Chandler wobble. The idea is pretty simple.

In the 1980s, laser gyroscopes began to take over the work of their mechanical, and later, electronic, forebears, without the slightest resemblance in principle or operation to the earlier devices.

2. Earth rotation is measured using a microresonator ring laser gyroscope: Counterpropagating SBLs are generated by counterpumping a microresonator (a).

Thanks to the sensitivity and stability of large ring laser gyroscope, the team were able to directly measure the combined effect of the Chandler and the annual wobble of the freely rotating Earth.

In laser gyroscopes, the ring-shaped path consists of a series of discrete mirrors that light bounces off of. Fiber optical gyroscopes, on the other hand, ...
