Abstract：This year， we have completed the research for latest international progresses related to the project subjects. Based on the theory of the light field reconstruction true 3D display， two methods of touchable light field 3D display are proposed. First we have verified the principle of the light field reconstruction method based on the light field stitching， and set up a demonstration system. We proposed an automatic geometriccalibrations method based on CCD camera and improved the fineness of splicing and imaging quality. Besides， we set up a high speed color DLP projector using 3 DMD devices. Using this projector， we set up a touchable light field display verification system， which has the view zone of 360 degrees. We analyzed the mechanism of integral imaging light field 3D display， and proposed a moiré-reduced integral imaging display method by tilting the elemental image array based on such mechanism. We also established a theoretical model for integral imaging light field pickup and display， and developed a 3D video-producing software and a 3D video player for integral imaging. We analyzed the mathematical relationships between the parameters of the reconstructed light field and the micro-lens array， as well as the restrictive correlations between them. We also preliminarily developed a liquid micro-lens array device.

Key Words：Touchable display； Light field scanning； Light field splicing； Integral imaging； Light field recording； Light field reconstruction
