Fragment-resolved momentum imaging for attosecond pump-probe measurement of intramolecular charge migration processes in polyatomic molecules is developed. Fluorescence from 2D detector is modulated with a light intensity modulator for recovering the temporal information on all kinds of fragment ions. This method enables us to record the momentum image of multiple fragment species simultaneously.
