Weak value has been proved to amplify the detecting changes of the meters at
the cost of power due to post-selection. Previous power-recycling schemes
enable the failed post-selection photons to be reselected repeatedly, thus
surpassing the upper noise limit and improving the precision of interferometric
systems. Here we introduce three cyclic methods to improve the sensitivity of
polarization-based weak-value-based angular velocity measurement: power-,
signal- and dual-recycling schemes. By inserting one or two partially
transmitting mirrors inside the system, both the power and precision of
detected signals are greatly enhanced, and the dual-recycling scheme has wider
optimal region than that of power- or signal-recycling schemes. Compared to
non-polarization schemes, polarization-based schemes enjoy lower optical loss
and unique cyclic directions. These reduce the crosstalk among different paths
of light and, theoretically, eliminate the walk-off effect, thus towering in
both theoretical performance and application.Comment: 7 pages, 3 figure
