Filtering of Digital Hologram

摘要：

　　With the development of computer technology and high-resolution charge coupled device (CCD),digital holography is widely used.However,there are noises in digital hologram inevitably,which is very unfavorable to reconstruct hologram and analysis fringes.From two aspects:frequency domain and space domain,we adopted mean filter,medium filter and Butterworth low-pass filterto remove the noise in digital hologram obtained with experiment.The experimental result showed that digital hologram was clearer and its contrast was enhanced.There was better reconstructing effect.
