平面一般位移场的代数重构算法

The Algebraic Reconstruction Techniques for Ordinary Plane Displacement Field

根据位移重构原理，提出了平面位移场代数重构的投影方式和相应的重构方式，算例说明了平面一般位移场代数重构（ＡＲＴ）的可行性，指出了实现正确重构的必要条件，并获得了高精度的重构结果．

According to the principle of displacement reconstruction, the projection and correspondingreconstruction mode is raised for 2-dimensional displacement field. The calculations show the feasibility of the reconstruction for ordinary plane displacement field, indicate the necessary conditions for correct reconstruction and obtain the results with high exactitude.
