Paper Abstract

High-definition computer holography based on the polygon-based method commonly uses the silhouette method to shield light behind objects for hidden surface removal. However, the light-shielding is not perfect and causes leakage light passing through many gaps between silhouette-shaped masks. Although we have proposed the principle of more rigorous technique to remove the leakage light, the technique has never been applied to the actual high-definition computer holography because of its long computation time. We propose some techniques to reduce the computation time and apply the rigorous technique to high-definition computer holography. A CGH created by the proposed method is demonstrated.
