用数字图像处理方法增强全息再现像

Strengthening the Holographic Reconstructed Image by Using the Digital Image Processing Method

数字全息中直透光和共轭像的去除是影响到全息能否得到更广泛应用的关键因素。介绍了全息图像中数字图像的基本原理,就数字图像的处理方法进行了探讨。

The elimination of the zero-order diffraction and conjugate image in the digital holography is the key factor influencing whether or not the holography is utilized widely, This paper introduces the basic principles of digital image in the hologram image, and probes into the digital image processing method.
