Holographic waveguide-type three-dimensional augmented-reality display using the holographic optical element-mirror array

摘要

We proposed a three-dimensional holographic waveguide-type augmented-reality system based on integral imagingusing the holographic optical element-mirror array. As same with the conventional holographic waveguide, twoholographic optical elements are utilized as in- and out-couplers that are located at the input and output parts of thewaveguide. The main role of these films is that reflecting the light beams come from the micro-display into thewaveguide, and transmitting the light beams to the observer’s eye. On the basis of the main advantages ofconventional holographic waveguide structure such as the light-weight and thin size, the proposed system has anadditional critical advantage that the observer can see the realistic three-dimensional visualizations reconstructed bythe out-coupler holographic optical element-mirror array, instead of simple two-dimensional images, with the realworldscenes at the same time. In the experiment, the augmented-reality feature has been successfully verified thatthe real-world scene and reconstructed virtual 3D image were observed simultaneously.
