Development of A Real 3D Display System

Abstract

This paper introduces a three-dimensional light field display system, which is composed of a high-speed projector, a directional scattering mirror, a circular stainless-steel bearing plate, a rotating shaft and a high-speed micro motor. The system reduces information redundancy and computational complexity by reconstructing the light intensity distribution of the observed object, thus generating a real three-dimensional suspended image. The experimental results show that the suspension three-dimensional image can be generated by properly adjusting the projection rate of the image and the rotation speed of the rotating mirror (i.e. the motor speed). The clarity and accuracy of a three-dimension display depending on the number of slices selected, meaning that the more slices can be projected per minute, the finer the three-dimension display. Finally, this study provides the basic parameter matching, which shows the feasibility of developing a real light field 3D display system with stable performance, strong portability, easy implementation, and low cost. In short, naked-eye 3D allows the observer to view objects from any angle and direction, without the need for any auxiliary tools (such as glasses, helmets, etc.).
