对于沿双轴晶体其中一个光轴聚焦的光束，由于晶体内锥形折射的影响，在焦像面上形成两个被暗环隔开的亮环。结果表明，当圆偏振的拉盖尔-高斯LG(0)(ℓ)光束进入晶体后，这种经典的双环模式转变为由ℓ+2个亮环组成的多环模式。
For a light beam focused through a biaxial crystal along one of its optical axes, the effect of internal conical refraction in the crystal leads to the formation in the focal image plane of two bright rings separated by a dark ring. It is shown that, with circularly polarized Laguerre-Gauss LG(0)(ℓ) beams entering the crystal, this classical double-ring pattern is transformed into a multiring one consisting of ℓ+2 bright rings.
