HIGH-DENSITY SPATIAL LIGHT MODULATOR

摘要

In one embodiment, a high-density spatial light modulator (300) includes a substrate (402) having a reflective surface (404) and a reflective ribbon (304) over the reflective surface. The ribbon (304) may have one or more openings, such as rectangular slots (308). The openings allow light to pass through the ribbon and impinge on the reflective surface. Deflecting the ribbon (304) towards the substrate (402) thus allows for dynamically-controllable diffraction of incident light. The spatial light modulator pixel requires less space than a conventional light modulator, thus allowing for relatively large pixel count within a manufacturable device size. Other embodiments are also disclosed.
