A pulse characterization scheme based on interferometric, spectrally resolved imaging of self-diffraction [1] is presented. Similar to interferometric FROG [2] and MEFISTO [3], interferograms of the nonlinear signal are recorded for different pulse delays. Due to the noncollinear nature of the setup, it can be applied to over octave spanning waveforms by separating signals on the spatial frequency axis. Additionally to the temporal waveform the method also resolves one spatial dimension and is therefore not limited by geometrical effects like beam smearing [4], known from other noncollinear schemes. In fact, both fundamental pulses can be recovered from the same measurement. The retrieval of the pulses is carried out solely in the (temporal) frequency domain and can be done analytically as well as iterative numerically which is more robust when dealing with noisy data.
