The Collins formula in spatial frequency domain is generalized into axially nonsymmetrical optical system in terms of tensor analysis method. Based on this formula, the tensor ABCD law in spatial frequency domain is derived.

• 运用张量分析方法把轴对称系统中的空间频率域的柯林斯公式推广到一般的非轴对称光学系统 ,并推导了在空间频率域中适用于非轴对称光学系统的张量ABCD定律。
