摘　　要：理论分析表明，用5束相干光干涉可以制作10重对称的准晶光子晶体．实验中，为了简化光路，利用5个光栅对一束平行光进行衍射，通过控制5个光栅的分布及光栅常数，进而得到制作10重对称准晶所需的5个光束偏转角度．实验结果与计算结果完全相符．
Ten symmetrical photonic quasicrystals can be created by interference of five laser beam by theoretical analysis. In the experiment in order to simplify the optical path, five making beams is obtained by parallel light diffracted by five gratings. Through adjusting the distribution of five gratings and grating constant, the required beam deflection angle is obtained. And the measured lattice constants are coincident well with the calculated values.
