A design method of anamorphic optical system

Anamorphic optical system has double-plane symmetry. it's focal length in the two symmetry planes are different. The anamorphic optical system can obtain a wider field of view when using sensors of conventional size. Based on the first-order aberration characteristics of anamorphic optical systems, a method for designing anamorphic optical systems is proposed in this paper. An anamorphic optical system is designed by using Biconic Surface.
