The relation between the viewing characteristics and the system parameters of the integral floating system, which is a brand new three-dimensional display technique, is analyzed. The system parameters considered include the focal length and the pitch of the lens array, the focal length of the floating lens, the image resolution of the integrated image, and the distance from the integral imaging system to the floating lens. The viewing characteristics of the integral floating are defined and described in terms of viewing window, floating image resolution, and floating image thickness. The ray-optical analysis is performed for the explanation of the viewing window and the floating image resolution, while the wave-optical methods are used to analyze the image thickness.
