[Paper] Depth Enhancement of Light Field Display by Multilayering Display Surface Using Lens Arrays with Multiple Types of Lenses

抄録

One of the problems with light field displays is that the resolution decreases the further away from the display surface. As a result, there is a limit to the displayable range in the depth direction. To solve this problem, the display surface is multilayered. By making the display surface multilayered, the distance between the display object and the display surface becomes closer, the resolution improves, and the displayable range in the depth direction is expanded. As a method to multilayer the display surface, this study proposes the use of two lens arrays with multiple types of lenses. In addition, this study proposes a method that allows a larger spacing between display surfaces using two lens arrays. Simulations are performed and it is confirmed that the display surfaces are multilayered and the resolution is improved.
