[net.sci] Circularly polarized light?

palmer@unc.UUCP (Thomas C. Palmer) (02/05/86)

   Light from two slide projectors polarized at right angles
and showing slightly different views of an object can be used
to produce a stereo effect when viewed through properly
polarized glasses.  This is intuitively easy to understand.

   I understand that circularly polarized light can also be
used.  In this case the light is polarized in opposite directions.
Producing linearly polarized light is straightforward.  Questions:

	- How is circularly polarized light generated?

	- How is this used to produce the stereo effect?

Thanks.
