 Fresnel predicted that if the prisms were cut from monocrystalline quartz with their optic axes aligned along the row, and with alternating directions of optical rotation, an object seen by looking along the common optic axis would give two images, which would seem unpolarized if viewed through an analyzer alone; but if viewed through a Fresnel rhomb, they would be polarized at ±45° to the plane of reflection.Confirmation of this prediction was reported in a memoir submitted in December 1822, in which Fresnel coined the terms "linear polarization", "circular polarization", and "elliptical polarization".In the experiment, the Fresnel rhomb revealed that the two images were circularly polarized in opposite directions, and the separation of the images showed that the different (circular) polarizations propagated at different speeds.
