Linearly polarized light has been used extensively as a means of encoding and decoding projected, superimposed stereoscopic images. An inherent property of such linear polarizer systems is that the observer wearing 3-D viewers must keep his head erect in order to maintain proper polarizer orientation and avoid troublesome ghost images. Circularly polarized light provides efficient extinction over a wide range of angular rotation, thus providing the opportunity to view 3-D comfortably with great freedom of head motion and position.
