Later , he coined the terms " linear polarization " , " circular polarization " , and " elliptical polarization " , explained how optical rotation could be understood as a difference in propagation speeds for the two directions of circular polarization , and ( by allowing the reflection coefficient to be complex ) accounted for the change in polarization due to total internal reflection , as exploited in the Fresnel rhomb .
