Integral wide angle diffuser screen
Nettet15. nov. 2024 · We propose a 360-degree viewable tabletop three-dimensional (3D) display system based on integral imaging by using a perspective-oriented layer (POL). The proposed system is composed of a two-dimensional (2D) display device, a POL, a lens array with large pitch and a light shaping diffuser screen. NettetThus for a given area ratio and given value of k, the configuration of the most efficient diffuser using a screen is that of narrow angle terminating in a wide angle. Concerning separation and filling, it is indicated that multiple screens in a diffuser of an arbitrary shape can be as effective as a single screen in a diffuser of a special shape.
