The Imbert–Fiodaraŭ effect (named after
Fiodar Ivanavič Fiodaraŭ (1911 – 1994) and Christian Imbert (1937 – 1998)
[http://e-ico.org/node/81] is an
optical phenomenon
Optical phenomena are any observable events that result from the interaction of light and matter.
All optical phenomena coincide with quantum phenomena. Common optical phenomena are often due to the interaction of light from the sun or moon wit ...

In electrodynamics, elliptical polarization is the polarization of electromagnetic radiation such that the tip of the electric field vector describes an ellipse in any fixed plane intersecting, and normal to, the direction of propagation. An elli ...
light undergoes a small sideways shift, when refracted or
totally internally reflected. The sideways shift is perpendicular to the plane containing the incident and reflected beams. This effect is the circular polarization analog of the
Goos–Hänchen effect
The Goos–Hänchen effect (named after Hermann Fritz Gustav Goos (1883 – 1968) and Hilda Hänchen (1919 – 2013) is an optical phenomenon in which linearly polarized light undergoes a small lateral shift when totally internally refl ...
