On a silicon wafer, a tiny grid of tunable crystals is used to control the magnitude and time delay, or phase, of reflected light shined at the surface of the chip from a laser. Software adjusts the crystals to create patterns of interference in the light, resulting in a three-dimensional light field.<\/p>\n<p>In experiments, the team has used the chip to create solid objects by projecting holograms into containers of various light-activated monomers.
