WebAbstract. An interferometer operating purely on the geometric phase is described. The optical paths traversed by the two beams in this interferometer are always equal, and the phase difference between the beams is varied by operating on the geometric phase WebThe phase of a circularly polarized beam passing through a half-wave plate is changed by an amount 2q as the half-wave plate is rotated an angle q. This phase shifting technique is especially useful in phase-shifting interferometry because the phase shift changes little as the retardation of the half-wave plate changes. For this reason the ...
