- W1978422026 abstract "In this paper, the reconstruction process of digital image's Computer Generated Hologram (CGH) is mathematically analyzed from the point of Discrete Fourier Transform (DFT). Based on such analysis, a convenient and effective method is proposed to improve the quality of digital image's CGH reconstruction. By eliminating the Direct Component (DC) of the DFT output of the hologram, the original digital image can be precisely reconstructed from the Burch CGH. Experiments have been done and the results show that the reconstructed realimage is exactly the same as the original digital image used to create the CGH, except that the pixel values are being scaled by some certain ratios. The experiment results also show that the proposed method can effectively improve the reconstruction quality of Huang's CGH and Wai-Hon-Lee's CGH." @default.
