摘　　要：近年来三维显示技术得到了学术界与工业界的广泛关注,其目标是使观察者在不佩戴任何辅助设备的情况下,使用裸眼观察到与实际物体近乎一致的三维图像。基于多层半透明薄膜结构实现了在平面上的三维显示。与传统的三维显示技术相比,这种显示技术的分辨率与对比度更高,结构也更加简单,易于制造。基于这种多层平面三维显示原型,进一步利用镜面反射原理,将其扩展成空间三维显示,使观察者可以在半空中多角度观察到虚拟的三维物体。Three-dimensional display technology, which aims at presenting almost-realistic three-dimensional images to the observer without any auxiliary devices, has drawn great attention from both academia and industry in recent years. In this paper, we implement a flat three-dimensional display using multi-layer semitransparent thin film structure. Compared to traditional three-dimensional display technologies, the proposed display technology has higher resolution, higher contrast, and simpler structure, thus easier to fabricate. Based on our prototype of flat three-dimensional display with multi-layer, we further extend it to spatial three-dimensional display using the principle of specular reflection, which allows observers to see virtual three-dimensional objects from different directions in the air.
