Abstract
It is possible to control the amplitude and phase modulation of light independently and simultaneously. The invention described here details how to do so by dividing a picture element into smaller modulating elements, providing independent addressing for each element, setting the necessary angle for each element and then resolving them into the picture element. The invention also show one embodiment of the invention.
