Color holographic magnification system based on spatial light modulators

In this paper, we propose a color holographic magnification system based on spatial light modulators. Three spatial light modulators are used to set up the system in our experiment by using space-division method. With the similarity principle of Fourier transform, the size of the reconstructed images can be magnified. By setting the green reconstructed image as standard and readjusting the sizes of the red and blue reconstructed images, the color images can be magnified to four times without chromatic aberration, which is verified by the experiment.
