Abstract
A method for multiple phase light modulation, said method comprising providing a pixel (20) having at least two modulating elements (22), (24). The method further comprising addressing said at least two modulating elements (22), (24) whereby light incident on said addressed element undergoes discrete phase changes between addressable states. The method further comprises resolving light from said at least two modulating elements (22), (24), into a response having at least three unique phases. Other devices, systems and methods are also disclosed.
