| 中文摘要 | a cascaded fresnel digital hologram (cfdh) is proposed, together with its mathematical derivation. its application to watermarking has been demonstrated by a simulation procedure, in which the watermark image to be hidden is encoded into the phase of the host image. the watermark image can be deciphered by the cfdh setup, the reconstructed image shows good quality and the error is almost closed to zeros. compared with previous technique, this is a lensless architecture, which minimizes the hardware requirement.
