Reflection Holography for Threedimensional Display Based on Computergenerated Holography
Both of the computergenerated holograms and optical holograms can be applied to a threedimensional display, but each has its own advantages and shortcomings. A novel technique is proposed based on the combination of computergenerated holography and reflection holography, which can overcome the limitation of optical holography. This technique can record realexisting objects and virtual objects, and achieve the reconstruction image by white light illumination. A 3D scanner is used to obtain 3D data of a realexisting object and calculate Fresnel holographic transmission distribution by point cloud algorithm. The Fresnel hologram is outputted by a holographic microfilming system. And, the reconstructed real image H1 of the computing hologram is used as the recording object for optical reflection hologram. The principle of this technique is explained in detail and the experimental results demonstrate that the technique is feasible.
