ABSTRACT:
A linearly polarized transparent or translucent material is stretched to follow a sinusoidal shape so all parts of the resulting panes or lenses are themselves sinusoidal. By providing a structure of two panes or lenses of such material, moving one relative to the other in a linear direction varies an amount of light passing through. Thus, such a linear movement adjusts light translucence, luminosity intensity, brightness and dimness. Applications include windows (home, office, car), motor vehicle windshields, sunglasses, optical lenses, computer monitors, televisions, and fluorescent light fixtures.
