Show affiliationsIn this paper, we present a technique to reconstruct a 3D object by its measurement data using a computer generated hologram (CGH). First, both the range image and the intensity image of a 3D object are acquired simultaneously using a 3D shape measurement system. Then, the Fresnel CGH is designed and fabricated using these data. Finally, by combining CGH with optical holography, an image hologram is recorded. This technique resolves how to obtain a 3D image in a CGH as well as how to reproduce the measurements of object images in three-dimensional object shapes. In this paper the principle behind the proposed method, the technology for designing and fabricating the CGH and optical hologram, and the experimental results are given.
