Taking a laser beam of astigmatic aberration as an example, the state of the laser beam compensating system can be given by the axial hologram of the laser beam.
我们以象散光束为例，根据轴向全息图能够给出该光束补偿系统的状态。

The purpose of the present paper is:(1)to build up a three-dimensional(3-D)model of simulating the propagation of circular Gaussina beam, simple and com-plex astigmatic Gaussian beam;
