‘World’s smallest optical gyroscope developed’
The new gyroscope, described in the journal Nature Photonics, is 500 times smaller than the current state-of-the-art device. Originally, gyroscopes were sets of nested wheels, each spinning on a different axis, said researchers from the California Institute of Technology in the US. However, today’s cellphones have microelectromechanical sensor (MEMS), the modern-day equivalent, which measures changes … Read more
