【摘要】 本文介绍利用数字像元全息图技术制作体视数字像元全息图的原理及一种通过对多幅图像灰阶和位移的编码合成体视数字像元全息图的方法。实验中确定单幅拍摄图像分辨率为400dpi,合成图像幅数为九幅。分别对九幅图像的像元光栅点的角度位移编码,实现多幅图像的叠加,制作出体视效果的数字像元全息图。并且按照不同的编码取向,可制作出不同观察效果的体视数字元全息图,观察的视觉效果与传统的三维拍摄的类似。它对模压全息标识的实际生产有一定的意义。更多还原

【Abstract】 The theory of making stereoscopic digital pixel hologram by digital pixelholography and a method of synthesizing stereoscopic digital pixel hologram with images’gray scales and displacements encoding are presented in this paper. Resolution of the singleimage were assigned to be 400dpi and nine images were taken in our experiment.Orientation and displacements of nine images’ pixel raster are separately encoded toaccomplish the overlap of images and made the digital pixel hologram with stereoscopiceffect. In term of different orientations stereoscopic encoding, the digital pixel hologramrepresents different stereoscopic effect. It looks like a traditional 3D rainbow hologram. Itmakes sense to practical production of embossing holographic label.更多还原
