In order to present a high-quality 3D image for integral imaging displays, it’s vital to correct the axial position error caused by misalignment and deformation of the lens array.

Additionally, a depth-based sub-pixel correction method is proposed to eliminate voxel drifting. Experimental results well confirm that the proposed measuring and correction methods can greatly suppress the voxel drifting caused by the axial position error of the lenses, and greatly improve the 3D image quality.
