Abstract:
A programmable beam blocker includes a liquid crystal based grid of pixels, one or more groups of pixels, or plurality of pixels, corresponding to individual beams of light. The application of a voltage through one pixel can change the phase of the liquid crystal material to prevent the transmission of light through it.
