Simple Fabrication Techniques of Fourier Transform Hologram with Gray Lever/Quasi-Colors and Visual Appearance of Opticall Reconstructed Diffractive Images Simple Fabrication Techniques of Fourier Transform Hologram with Gray Lever/Quasi-Colors and Visual Appearance of Opticall Reconstructed Diffractive Images 飯塚, 昌行 3067 イイズカ, マサユキ 大熊, 良夫 453 オオクマ, ヨシオ 中嶋, 芳雄 3066 ナカシマ, ヨシオ IIZUKA, Masayuki 917 OOKUMA, Yoshio 918 NAKASHIMA, Yoshio 919 A binary computer generated hologram (CGH) and a Fourier transform hologram (FTH) with gray level/quasi-colors are similar to all appearance in the structure of hologram cell. However, they are wholly distinct each other in display techniques. We directly take a picture of reduced size of FTH displayed on a standard color LCD/CRT using a special negative film with high contrast in this study. A few examples of optical diffractive images are demonstrated for the comparison of the proposed FTH techniques with the classic binary CGH techniques from the viewpoint of visual appearance and image quality. 7 KJ00000124160 論文 Article departmental bulletin paper 2000 application/pdf 東京工芸大学工学部紀要 1 23 35 46 The Academic Reports, the Faculty of Engineering, Tokyo Polytechnic University AN00159741 03876055 https://kougei.repo.nii.ac.jp/record/347/files/KJ00000124160.pdf https://kougei.repo.nii.ac.jp/records/347 eng
