Abstract
Microelectromechanical systems based spatial light modulators (SLMs), and display systems and methods for operating the same are described. Generally, the SLM includes a linear array of a number of electrostatically deflectable ribbons suspended over a surface of a substrate. Each ribbon includes a split-ribbon portion with a plurality of diffractors, each diffractor including a first light reflective surface on a linear portion of the split-ribbon portion and an opening through which a second light reflective surface affixed to the substrate is exposed. The first light reflective surface and the second light reflective surface have equal areas, and when one or more of the ribbons is deflected towards the surface of the substrate a coherent light reflected from the first light reflective surface is brought into constructive or destructive interference with light reflected from the second light reflective surface. The display system can include a projector or a head mounted unit.
