摘　　要：根据电磁场的边值关系,导出了不同于菲涅耳公式的晶体界面光振幅的关系,提出了晶体锥光干涉中两相干光的位相差和振幅的计算方法.计算结果用数字图像表示,能够直观地显示出晶体锥光干涉图的特征.对不同取向的铌酸锂晶片进行实验,实验干涉图与理论干涉图的特征完全一致.According to the boundary conditions of the electromagnetic field, relation of electric field amplitude on crystal interface has been deduced, which differs from Fresnel formula. Calculation method about phase difference and amplitude in interference pattern of convergent light has been proposed. Experiment of the conoscopic interference was completed for LiNbO_3 crystals with different direction. The calculated results well coincide with the experimental results.
