ホログラフィックディスプレイの現状と課題

抄録

Holography is an ideal three-dimensional display technique. However, its electronic implementation requires light modulation by tremendous number of pixels whose pitch should be comparable to the wavelength of light. In this paper, several techniques proposed to overcome the above difficulty are shown; the technique using multiple spatial light modulators, the time-multiplexing technique, the technique using acousto-optic modulators, the resolution redistribution technique, and the horizontally scanning technique. Especially, the horizontally scanning technique is explained in detail; it is realized using the screen scanning system and the viewing-zone scanning system. The 360-degree holographic display is also realized based on the latter system.
