Title:
エレクトロホログラフィックディスプレイにおける実効画素ピッチを低減する方法及び低減された実効画素ピッチを含むエレクトロホログラフィックディスプレイ
Document Type and Number:
Japanese Patent JP2009540353
Kind Code:
A
Abstract:
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.
