Abstract: Ultrafast photoelectron holography is studied by solving a 3-D time-dependent molecular Schrödinger equation and a corresponding classical model. We report subcycle interference dynamics between direct and rescattered photoelectrons. Four different interference patterns are predicted by the classical model[1], and used to interpret the quantum simulations, involving forward and backward rescattering in above threshold ionization (ATI). The numerical simulations provide attosecond time-resolved tools for the electronic
imaging of molecular structure [2]. Dynamic imaging of a linear
symmetric molecule H2+ and dipolar molecule HeH2+ are studied
as examples.
