Abstract

Three-dimensional imaging is important content of computer vision and image processing. However,3D image showed on CRT is really 2D, failing to provide many visual depth cues. Technology of 3D holographic imaging can create true 3D image with all depth cues (motionparallax, ocular accommodation, occlusion, etc) and resolution sufficient to provide extreme realism. Diffraction Specific CGH Algorithms by Lucente whilst at Spatial Imaging Group of MIT Media Laboratory, which progress in diffraction-specific fringe computation of 3D holographic imaging, computation of basis fringes is according to a point imaging. In this papaer, we propose a new method of computing the basis fringe with wavelet transform, computed basis fringe function, analyzed spectrum of basis fringe, realized basis fringe model in Physics and completed a display of a spatial point image. Experimental results show that the method proposed in this paper is obviously advantageous and robust.
