We show theoretically and experimentally that a simple modification of the dynamic spectrogram may be used to characterize a stochastic ensemble of ultrashort optical pulses. The method makes use of the temporal analysis of spectral components to measure an intuitive spectrogram of the ensemble using a low order nonlinear technique. Pulse-shape reconstruction is demonstrated via an iterative inversion algorithm for an ensemble of identical input pulses. For pulses that are not identical, we measure for the first time a representation of the two-time correlation function of the pulsed field, using a non-iterative decorrelation procedure.
