Undistorted pickup method of both virtual and real objects for integral imaging

Abstract

Optically corrected pickup method of both virtual and real objects for integral imaging is proposed. The proposed pickup system has imbricate view volumes which are equivalent to those in the integral imaging display. Therefore, there is no distortion resulting from the discord in directions of elemental image between pickup and display. In this system, the view volumes are transformed by 4f optics and the directions of view are defined by lens array and telecentric lens. Without computational cost for compensation, the pickup of both real and virtual objects is confirmed experimentally.
