Researchers have developed a ” holographic display built with standard semiconductor processes; Francesco Pessolano, manager of Imec’s NVision program, suspects detailed 3-D video displays can be made by moving reflective microelectromechanical systems (MEMS) structures up and down like microscopic pistons.” Video demonstration after the break.

After topping that entire grid with a fine layer of reflective aluminum, they shine laser light onto the pixels at an angle, and the varying ways this light diffracts from the uneven surface they’ve created cause the light to interfere with itself both constructively and destructively. Long story short, if the pixels have been precisely etched a 3-D holographic still image emerges.
