Effect analysis of local error on image quality in integral imaging display system

The effect of the local error in the display module on the reconstructed image quality of the integral imaging system is analyzed. First, the geometric optics and the ray tracing theory are utilized to build the local error theoretical model based on the integral imaging principle by considering the optical axis transform and the pixel information dislocation. The simulation experiments are carried out to verify the validity of the above analysis. Experimental results show that the homologous points on EIs form two separate images. The separation distance depends on the local error, the size of the lenslet and the magnification ratio of the integral imaging system.
