Display depth analyses with the wave aberration for the auto-stereoscopic 3D display

• The Fresnel diffraction theory is used to analyze the reconstructed process of the reconstruction volume pixel (RVP) from corresponding pixels and the diffraction field distribution.
• To calculate the display depth with aberration, the minimum angular resolution of human eyes is taken into consideration.
• A set of experimental results demonstrate the correctness of proposed method.
• In addition, increasing the viewing distance or decreasing the lens aperture can improve the display depth.
• Different viewing distance and the LCD with two lenticular sheets are used to verify the conclusion.

Because the aberration severely affects the display performances of the auto-stereoscopic 3D display, the diffraction theory is used to analyze the diffraction field distribution and the display depth through aberration analysis. Based on the proposed method, the display depth of central and marginal reconstructed images is discussed. The experimental results agree with the theoretical analyses. Increasing the viewing distance or decreasing the lens aperture can improve the display depth. Different viewing distances and the LCD with two lens-arrays are used to verify the conclusion.
