Analysis on the 2D/3D convertible display system based on the integral imaging technique

摘要

Recently, a two-dimension/three-dimension (2D/3D) convertible display system based on the integral imaging technique was proposed. The 2D/3D convertible system shares similar characteristics with integral imaging, but the analysis on the integral imaging cannot be directly applied to the 2D/3D convertible system. In this paper, the 2D/3D convertible display system is analyzed using wave optics to consider the effect of diffraction which plays an important role since the dimension of the 2D/3D convertible system is fairly small. First, the equation that governs the diffraction effect in the three-dimensional image display mode of the 2D/3D convertible system is derived assuming monochromatic and coherent point light source. Based on the equation, simulations and analyses of the 2D/3D convertible system are given.
