Experimental observation of the Imbert-Fedorov transverse displacement after a single total reflection

摘要

We describe a simple experimental setup with which to observe the transverse shift—also known as the Imbert-Fedorov effect—that circularly or elliptically polarized optical beams undergo after a single total internal reflection on a dielectric plane. A comparison between a theoretical model based on the conservation of energy and experimental measurements shows good agreement simultaneously for longitudinal (Goos-Hanchen) and transverse (Imbert-Fedorov) displacements.
