Abstract
We propose an integral imaging 3D display based on top‐hat diffusing screen. The integral imaging 3D display consists of a 2D display, a micro‐lens array, and a top‐hat diffusing screen. The top‐hat diffusing screen is composed of multiple elemental lenses with different pitches. The light rays pass through the top‐hat diffusing screen to form a regular light spot, and the light intensity distribution of the light spot is top‐hat type. This can make the 3D image smooth and natural. The experimental results verify the feasibility of the proposed integral imaging 3D display.
