Abstract

We propose an advanced holographic see-through display system with 3D/2D switchable modes based on a liquidcrystalline lens array and a one-shot learning model. The liquid-crystalline lens array switches its role that act like a lens array or glass, according to the state of the electrical polarizer. When the switch of an electrical polarizer is on-state, the camera captures the image of a real-world object, and a one-shot learning model estimates the depth data from the captured image. Then, the 3D model is regenerated based on both color and depth images; and the elemental image array is generated and displayed on the microdisplay while the liquid-crystalline lens array reconstructs as a 3D image. On the other hand, when the switch of the electrical polarizer is off-state, the camera captures the image of a real-world object and is directly displayed by the microdisplay, while the liquid-crystalline lens array simply transmits it to the holographic combiner. The experimental results confirmed that the proposed system can be an advantageous way to implement the 3D/2D switchable holographic see-through system.
