- Abstract
In this paper, we demonstrate a color holographic system without undesirable light based on area sampling of a digital lens. This system, which improves the quality of the reconstructed color image, is fundamentally realized by using three spatial light modulators and a rectangle aperture. By altering the sampling area of the digital lens on the spatial light modulator panels, we can control the offset position of the reconstructed image. Thus, the zero-order diffraction light as the undesirable light and the reconstructed images are separated, and the chromatic aberration can be corrected. In addition, a rectangle aperture is used to eliminate the zero-order diffraction light. The final reconstructed image with improved quality can be observed, which verifies the effectiveness of our proposed system.
