Distortion-Corrected Integral Imaging 3D Display System Based on Lens Array Holographic Optical Element

We propose a distortion-corrected integral imaging (II) 3D display system based on lens array holographic optical element (LAHOE). The LAHOE is used as projection screen. beam of the parallel light. Hence, consists spatial light modulator, reverse lens, relay element, and telecentric lens. acquired data reconstructed image II are symmetrically related to each other. Therefore, there distortion in system. To avoid affecting viewing experience viewers, elemental (EIA) projected obliquely LAHOE, causing lateral EIA. There position deviation system, so EIA has geometric deformation. Due EIA, it difficult precisely align which results serious flip images. affects asymmetry reconstruction. Lens can be solved by compensation method. Lateral deformation perspective transformations computer graphics. After correction, undistorted projected, little distortion. In process reconstruction, causes reconstruction analyzed, issues that generate these asymmetric factors addressed. Experimental indicate better effect achieved.
