Abstract
We show that Doppler shifts are fundamental in gyroscopes. The implication is that it is then possible to perform frequency estimation rather than phase estimation in a passive gyroscope. By utilizing the ultra-steep gain feature of a liquid crystal light valve, we were able to show that we could beat the standard quantum limit of phase estimation by two orders of magnitude compared to a standard interferometer of the same size.
