研究了由三个光学双轴KGd(WO4)(2)晶体组成的级联锥形衍射系统。研究了左、右手圆偏振入射光对远离系统焦像平面（即晶体各向同性时入射光束束腰聚焦的平面）的环形图案的影响。图像和强度分布缩放距离（zeta值）为2.75,3.00和3.25的焦点图像平面。根据入射光束的旋向性产生的模式之间的差异与最近的理论预测一致。(C) 2012美国光学学会
A cascade conical diffraction system consisting of three optically biaxial KGd(WO4)(2) crystals is considered. The effect of left-and right-handed circularly polarized incident light on the ring patterns produced away from the focal image plane of the system, the plane in which the incident beam waist would be focused if the crystals were isotropic, is investigated. Images and intensity distributions for scaled distances (zeta values) of 2.75, 3.00, and 3.25 from the focal image plane are presented. A discrepancy between the patterns produced depending on the handedness of the incident beam is observed in agreement with the recent theoretical predictions. (C) 2012 Optical Society of America
