Reaction Microscope-based, complete and time-resolved Coulomb explosion imaging of vibrating and dissociating D2+ molecules with femtosecond time-resolution allowed us to perform an inter-nuclear distance (R-)dependent Fourier analysis of the corresponding wave-packets. Calculations demonstrate that the obtained two-dimensional R-dependent frequency spectra enable the complete characterization of the wave-packet dynamics and directly visualize the field-modified molecular potential curves in intense, ultrashort laser pulses.
