When the end of the electric field vector travels in an ellipse, the light is elliptically polarized.
He spoke only briefly and elliptically about the mission.

Detecting elliptically polarized light using compound quarter-wave plate
Field integral shimming of elliptically polarized undulator at Shanghai synchrotron radiation facility
Linearly polarized light will in consequence become elliptically polarized on total reflection.
