| Abstract: | The digital reconstruction technique is applied to the reconstruction process of the T.S. Huang’s Fourier computer generated hologram (CGH). The CGH is made and reconstructed directly through the method of digital reconstruction. By using digital image processing method directly, twin-images and zero-order of diffraction images are eliminated and clear real-image are obtained. The CGH of the computer image is presented in this paper, together with the results of digital reconstruction. |
