摘要：

An asymmetric transfer function - based on the symmetric one used in optical cases to correct blurring and defocusing effects in systems with circular aperture - is presented here to restore STM (scanning tunneling microscopy) images. A Wien filter is implemented that utilize this transfer function. In the STM case, the defocusing has two different origins depending on the scan direction that produce a set of two fitting parameters.
