Analysis of the relationship between display depth and 3D image definition in light-field display from visual perspective

An analysis method for the relationship between light-field display (LFD) depth and 3D image definition from visual perspective is presented in this paper. A simplified analytical model suitable for standard LFD system is established, which can be used to analyze the formation of voxels from a perspective that is more consistent with visual perception. Moreover, the formula for calculating voxel size is derived in relation to the depth plane and viewing position. Reasonable simulation programs and LFD devices with different parameters are used in experiments to verify the correctness of the theoretical analysis. The analysis and experimental results presented in this paper may contribute to a better understanding of the principle of light-field display, and it is helpful to design and optimize the LFD system with better display effect.
