Title:
VARIABLE TRANSMISSION WINDOW
Document Type and Number:
WIPO Patent Application WO/2012/092443
Kind Code:
A4
Abstract:
The various embodiments include variable optical transmission devices with uniform or patterned polarizers or wave retarders configured to provide continuous or nearly continuous variations in light transmission based on linear translation. For example, embodiments include a variable transmission window including a first uniform polarizer with a first polarization axis, a second uniform polarizer with a second polarization axis, a first patterned wave retarder positioned between the first and second polarizers and including a first plurality of domains configured to vary in at least one of optic axis, thickness, or birefringence, and a second patterned wave retarder positioned between the first and second polarizers and including a second plurality of domains configured to vary in at least one of optic axis, thickness, or birefringence. The first or second wave retarder is configured to be linearly translatable relative to the other wave retarder.
