Abstract
We propose and experimentally demonstrate a universal method for dynamic Fourier analysis of continuous broadband high-speed non-stationary fields by mapping the full spectrogram of the incoming waveform onto the temporal domain. The full spectrogram of a GHz-bandwidth microwave signal, sampled by an optical field, is directly captured in a real-time scope, at record speed.
