| Outline of Final Research Achievements |
The objective of this research was to develop a system that combines full-color CGH computation (capturing and recording), wireless transmission, and display. In order to realize a full-color CGH wireless transmission system that is free from the effects of image quality degradation caused by transmission errors. Through this research, the effects of transmission errors that occur during wireless transmission of CGH on CGH itself and the effects of image quality degradation caused by transmission errors on reproduced images were clarified through simulations and optical reconstructed experiments. The feasibility of wireless transmission of full-color CGH without image quality degradation due to transmission errors and the feasibility of streaming of full-color 3D moving images were investigated.

CGHの計算方法やCGHを表示する光学系に関しては盛んに研究されているが，計算したCGHを表示装置へと伝送する研究については数少なく，未解明な点が多かった．本研究では，伝送時に生じる伝送エラーがCGHの再生像へ与える画質劣化の影響を検討し，理論的・実験的にその影響について研究をおこなった．特にフルカラー再生像に与える画質劣化について，波動光学に基づく数値解析により画質劣化の光学的特徴を明らかにし，実環境下におけるCGHの無線伝送とフルカラー再生化の実現生について検討を行った．これにより，計算したCGHの伝送の自由度が向上し，HMDベースのCGH表示などへの応用が期待できる．
