The diffraction patterns of a conical lens illuminated by plane and spherical waves have been intensively investigated. A practical method is described to transform the Bessel profile of a zero-order Bessel beam into a caustic one through the use of a combination of a conical lens and a cylindrical lens, which in turn transforms the field generated by the conical lens. The cylindrical lens was illuminated by a zero-order Bessel beam, producing a lips caustic beam. It is shown that this type of wave tends to regenerate during propagation, although the waves are severely perturbed.
平面波和球面波照射下圆锥透镜的衍射图样已得到深入研究。描述了一种实用方法，通过结合使用圆锥透镜和柱面透镜，将零阶贝塞尔光束的贝塞尔轮廓转换为焦散轮廓，进而改变圆锥透镜产生的场。柱面透镜由零阶贝塞尔光束照射，产生唇形焦散光束。结果表明，尽管波受到严重扰动，但这种类型的波在传播过程中倾向于再生。
