Summary

Description
English: This circularly polarized light is considered left-handed as viewed from the receiver and right-handed as viewed from the source. (Refer here)

A homogenous circular polarizer can be created by sandwiching a linear polarizer between two quarter-wave plates. We take the circular polarizer described previously, which transforms circularly polarized light into linear polarized light, and add to it a second quarter-wave plate rotated 90° relative to the first one. The linearly polarized light that is created by the first quarter-wave plate and then passes through the linear filter is transformed back into left handed circularly polarized light. Right handed polarized light entering would be blocked by the linear polarizer. As a result such circular polarizers pass one handedness of circularly polarized light, unaltered, but block the other polarization. Generally speaking, when either of the two polarizations of circularly polarized enter the first quarter-wave plate, their horizontal components are retarded by one quarter wavelength relative to the vertical component, creating one of two linear polarizations. Depending on which handedness the circularly polarized light is, the linear polarizer will either pass the light or block it. The second quarter-wave plate then retards the vertical component of the linearly polarized light that does pass through the linear polarizer bringing the two components back into their initial phase relationship. By rotating the linear polarizer 90° relative to the quarter-wave plates one can change which handedness of circularly polarized light passes unaltered and which gets blocked.


This image was created using the open source program Inkscape. If you open it using that program the image will still be divided into layers and you will have access to information used to create it. If you need to alter it I would suggest first going to my Wikimedia User page at Dave3457 where information is gathered and other related images are listed.
