Abstract

A large viewing angle 3D light-field display based on a single lens array with the optical-digital joint optimization algorithm is proposed. Aberrations generated by the single lens array are suppressed with the presented algorithm to increase the viewing angle. The proposed algorithm consists of aberration optional-correction module and digital image optimization module. Some aberrations selected by aberration analyses are suppressed to zero or minimums with the single lens unit optical structure in aberration optional-correction module, and residual aberrations are suppressed by pre-correcting based on Wiener filtering in digital image optimization module. Experimental results confirm that the optical-digital joint optimization algorithm can suppress aberrations effectively, and a 52-degree viewing angle 3D light-field display is realized.
