The use of index medium for viewing angle enhancement in integral imaging

摘要

In conventional integral imaging, the viewing angle is limited by the size of elemental image and focal length of the corresponding elemental lens. In this regard, the proposed method employs a refractive index medium. The viewing angle enhancement depends on the refracting property of the ray light from high index medium to lower index. In this paper, viewing angle enhanced integral imaging system is analyzed. The experiment is carried out using planoconvex lens array with and without refractive index medium, and the results are compared.
