Three-dimensional visualization of shape measurement data based on CGH

Abstract

In this paper, we propose a technique to reconstruct 3-D object shape by its measurement data using CGH.Firstly, both the range image and the intensity image of 3D object are acquired simultaneously using 3D shape measurement system. Then, the Fresnel CGH is designed and fabricated using these data. Finally, combining CGH with optical holography, an image hologram is recorded. The principle of the proposed method, the technology for designing and fabrication of the CGH and optical hologram, and the experimental results are also given in this paper.
