Abstract

A rapid algorithm of multi-plane holographic display is given. A proper thin lens phase factor was combined with fast Fourier transform (FFT) in this algorithm to move the reconstructed image of Fourier transform hologram to specify depth from infinity and the imaging effect of this algorithm is identical with Fresnel diffraction. Using this simple operation replaced complicated Fresnel diffraction integral in the Ping-Pong iteration algorithm, the computational load of multi-plane hologram was reduced and computational speed was significantly increased. Moreover, the hologram of a 3-D object consists of two pictures at different depths was computed by this modified Ping-Pong algorithm. The reconstructing of this obtained hologram was also simulated in MATLAB. The result showed the new algorithm is feasible and effective.
