体视数字像元全息图的研究

The principle, method and an arrangement of making stereoscopic digital pixel hologram are studied in our work. Conception of digital dot matrix combination unit is presented. The relation between the coding regularity of the combination unit and the stereoscope result of digital pixel hologram are studied. An etching arrangement of digital pixel hologram making stereoscopic hologram is made by us. Good qualitative stereoscopic digital pixel hologram is made using this arrangement. Technique and an arrangement of making synthetic stereoscopic hologram using digital micromirror device (DMD) are studied. We got a patent for an arrangement of making synthetic stereoscopic hologram. These new technology are very useful and powerful for production of holographic paking material of goods and anti-counterfeiting of quality goods and negotiable securities.

在研究数字像元的基础上,提出数字点阵组合的概念,同时研制出有立体视觉效果的数字点阵组合元的编码规律.基于数字点阵组合元的概念和体现数字像元全息图刻蚀系统制作的体视.数字像元全息图除具有虚拟的立体视觉效果外,其分辨率较常规数字像元全息图提高三倍以上.在防伪包装上有实用价值.
