METHOD OF REDUCING EFFECTIVE PIXEL PITCH IN ELECTROHOLOGRAPHIC DISPLAY AND ELECTROHOLOGRAPHIC DISPLAY INCLUDING THE SAME |
摘要 |
An electroholographic display system (500) includes a coherent light source (130) adapted to produce a coherent, collimated light beam, a spatial light modulator (SLM) (120) adapted to modulate the light beam, an optical unit (350, 450) in an optical path between the SLM (120) and the image plane (580) where a holographic image is projected. The optical unit (350, 450), which may include a pair of convex lenses (460, 470), operates to effectively decrease the pitch (220) of the pixels (210) of the SLM (120). This allows the electroholographic display system (500) to exhibit a desired range of diffraction even when it includes an SLM (120) whose pixel pitch (220) is larger than would otherwise be required for the desired diffraction range. |
