By using the complex Gaussian expansion of the aperture function and the generalized integral formula ,an approximate analytical formula for an anomalous hollow beam passing through a hard-apertured misaligned paraxial optical system is derived .As an application example ,the propagation properties of an anomalous hollow beam through a hard-apertured misaligned thin lens are studied by numerical calculations . The results show that , the normalized intensity distribution of the output beam and the propagation properties are closely related with the factors of aperture width ,the misalignment and the transmission distance .
