Abstract:

To solve the problem of the narrow viewing zone in electro-holography, we propose a method using eye-tracking and a property of holography where the viewing zone varies with the angle of the reconstruction light. The method can enlarge the viewing zone without moving the optical elements for higher-order diffracted light removal and high-refresh-rate devices. The size of the reconstructed image is also enlarged using lenses. We conducted an experiment to validate the effectiveness of our method, and the results indicate that the viewing zone was enlarged by 1.44 times and the size of the reconstructed image was enlarged by 1.49 times.
