我们开发了一种全息三维(3D)显示器,通过使用非平面光学元件产生发散的宽展开角球面波,使全息显示比传统的平面全息图具有更宽的观看区域。采用凸抛物面反射镜和非平面全息光学元件作为非平面光学元件。如果计算全息图设计得当,考虑到非平面光学元件上的反射,则可以将其中的3D物体再现为虚拟图像。观察者可以从3D物体的外围观察3D物体,光学实验成功地演示了我们提出的方法。
We have developed a holographic three-dimensional (3D) display with a wider viewing zone than conventional planar holograms by using a non-planar optical element generating a diverging spherical wave with a wide spreadangle. The convex parabolic mirror and non-planar holographic optical elements were used as such non-planar optical elements. If the computer-generated holograms are designed properly considering the reflection on the non-planar optical elements, a 3D object can be reconstructed inside them as a virtual image. Viewers can observe 3D objects from the periphery of the 3D object, and optical experiments successfully demonstrated our proposed methods.
