After a total internal reflection on a dielectric interface, a light beam elliptically polarized undergoes simultaneously longitudinal (or Goos-Hänchen) and transverse (or Imbert-Fedorov) shifts. An original experimental set-up based on the combination of a liquid crystal valve and a position sensitive detector has been implemented to observe this two-dimensional displacement after a single total reflection. The experimental results are compared with numerical models based on energy conservation originally proposed by Renard model and show a good agreement between theory and experiment.
