Abstract

A three-dimensional (3D) digital holographic display system with image processing is presented. By use of phase-shifting digital holography, we obtain the complex amplitude of a 3D object at a recording plane. Image processing techniques are introduced to improve the quality of the reconstructed 3D object or manipulate 3D objects for elimination and addition of information by modifying the complex amplitude. The results show that the information processing is effective in such manipulations of 3D objects. We also show a fast recording system of 3D objects based on phase-shifting digital holography for display with image processing. The acquisition of 3D object information at 500 Hz is demonstrated experimentally.

摘要

本文提出了一种具有图像处理功能的三维（3D）数字全息显示系统。通过使用相移数字全息术，我们在记录平面上获得三维物体的复振幅。引入图像处理技术以提高重建三维物体的质量，或通过修改复振幅来对三维物体进行信息消除和添加的操作。结果表明，信息处理在三维物体的此类操作中是有效的。我们还展示了一种基于相移数字全息术的三维物体快速记录系统，用于配合图像处理进行显示。实验证明了以500赫兹的频率采集三维物体信息的可行性。
