简易三维立体投影装置制作

摘要

本文报道了一种便携式简易三维立体投影装置：用四个透明反射板拼接成空心梯台，视线能从任何一面穿透，通过投影口放置的视频播放设备产生图像，图像经表面镜射和反射，从而在空心梯台的空间内形成可见的三维影像。该装置制作简单，便于携带，很好地实现了手机等便携式电子设备所播放图像或视频的三维立体投影显示。%This work presents the fabrication of a portable and simple three-dimensional stereoscopic projection device,which is assembled by four transparent trapezoidal reflecting plates to form a hollow tetrahedral cage where the optical line of sight can penetrate from all the side panels. By placing a video playback device on the upper side of the cage to play images,visible three-dimensional images are formed inside the hollow chamber of the cage due to the surface reflection. This device is easy to make and carry,achieving the well-displaying of the images or videos that played by the portable electronic devices such as mobile phones in the form of three-dimensional stereoscopic projection.
