A method, an apparatus, and a computer program product for modulating optics in a display are provided. An apparatus forms a plurality of zone plates in a liquid crystal using electric fields. Each zone plate has a center, and the centers are aligned along a first axis of the display. The apparatus moves the plurality of zone plates in a first direction along a second axis of the display different from the first axis of the display, while maintaining alignment of the centers of the plurality of zone plates along the first axis. Such movement is provided through repositioning of electric fields through the liquid crystal.
