Considering the interaction of the electric field of the incident light and piezoelectric lattice vibrations at infrared frequencies, we proposed the relationships to describe eigenvibrations in alpha-quartz. Orthogonal eigenvibrations are found to be the correlated oscillations with mutual coherence. Such arguments were confirmed by generation of polarized waves on reflection of randomly polarized incident light from alpha-quartz. By incidence of randomly polarized infrared light, the reflected waves are found to be polarized and vibrate in two directions of eigenpolarizations with mutual coherence, corresponding to the ordinary and extraordinary waves, respectively. This observation provides a novel technique to develop the new type of polarizer in the infrared frequency region.
