双四棱锥偏振全息三维立体成像装置

A Double-Quadrangular Pyramid Polarization Holographic Three-Dimensional Imaging Device

基于光的偏振原理,本文设计和构建了一种新型的全息三维立体成像装置。该装置的基本成像单元为透明亚克力薄板构成的空心正四棱锥结构,两个该四棱锥相互嵌合并加装偏振片构成全息三维立体成像系统。投影源为分别放置于该成像系统上下两侧的平板电脑。投影源投出的光经过偏振片转换为偏振光,经成像系统反射后到达人眼时偏振角度夹角为90°,经偏振3D眼镜观察可见逼真的全息三维成像效果,实现立体成像。本文的设计为大学物理光学综合性实验提供了新的素材。

Based on the principle of light polarization,a new type of holographic three-dimensional imaging device is designed and constructed.The basic imaging unit of the device is a hollow square pyramid structure composed of transparent acrylic sheets,two pyramids are fitted with each other and polarizers are added to form the holographic three-dimensional imaging system.The projection source are two tablets placed on the upper and lower sides of the imaging system.The light projected by the projection source is converted into polarized light by the polarizers,and the polarization angle is 90°when it reaches the human eye after being reflected by the imaging system.Observed by polarized 3D glasses,a realistic holographic three-dimensional imaging effect can be hence observed,achieving the three-dimensional imaging.The design of this article provides new materials for the comprehensive optical experiments for the university physics.
