Supermirror phase anisotropy measurement.
The high sensitivity of the eigenstates of a large-finesse passive Fabry-Perot cavity is used to measure the residual anisotropy of supermirrors at strictly normal incidence. An experimental demonstration leads to the measurement of phase retardances of the order of 10(-6) rad.
