In order to decrease the wave aberration, we propose to use the parallel light as reference light, and reconstruct the master hologram by using the inverse light road.
为了把波像差的影响减少至最小，我们建议使用平行光做参考光，并用逆光路再现母全息图。

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.
