Visualization Using Computer-Generated Hologram (CGH) Based on Three-Dimensional Shape Measurement Data of Object
A technique of reconstructing 3 D object shape by its measurement data using CGH is proposed. Firstly, both the range image and the intensity image of 3 D object are acquired simultaneously by using 3 D sensing system. Then, the Fresnel CGH is designed and fabricated. The problem of combining CGH with optical holography, an image hologram is recorded. This technique resolves how to obtain 3 D data in CGH as well as how to reproduce the object images in measurement of 3 D object shapes. The principle of the proposed method, the technology for designing and fabrication of the CGH and optical hologram and the experimental results are given.
