Paper Abstract

In the paper, the main properties of Moire fringe, such as average effect, amplification effect, corresponding relation are elaborated, and the principle of Moire Ct technique is represented. On the basis of main features of Moire fringe, multidirectional Moire Ct deflection system is designed using high accuracy Ccd, grating, filter, lens, planar mirror and optical splitter. The system has simple light path, and can be easily made into the one that has large caliber.It can analyze multidirectional records of the probe at the same time, and can obtain clear interference patterns.The iterative technique combined with computer chromatography algorithms is used to achieve inversion of multidirectional clear interference patterns so that the required parameters can be acquired. Moire Ct technique is applied to laser flexible manufacture. Produced parts are delaminated on the paper, and are stratified manufactured until they are connected to forming. Cad/Cam system is adopted to construct Spatial three-dimensional geometric model, and the data files are formed. Then by using the Small triangle plane, the inner and outer surfaces of the data files are discretized. Discretized parts model is made chromatography with mathematical methods using Cam software. A series of parallel horizontal intersecting planes are generated. The problems of filtering arrangement tangent points are solved by recombining the shape and structure relationship among the triangular mesh. Several conclusions are presented.
