Abstract
We proposed a new algorithm that retrieves the projected potentials from the EW of object. This algorithm is based on the traditional multislice method which involves the convolution operation in calculation. The retrieved potential is complex including both the electrostatic and absorptive components. Tests with the simulated exit waves of a 200 K InP crystal prove the algorithm effective for objects in wide thickness range. For thick specimen where dynamical electron diffraction prevails, the retrieved potential could present structure and chemical information of object by completely mapping an atom's scattering potential during interaction with incident electrons.
