    "abstract": "Time-resolved optical filtering (TROF) measures the spectrogram or sonogram\nby a fast photodiode followed a tunable narrowband optical filter. For periodic\nsignal and to match the sonogram, numerical TROF algorithm is used to find the\noriginal complex electric field or equivalently both the amplitude and phase.\nFor phase-modulated optical signals, the TROF algorithm is initiated using the\ncraters and ridges of the sonogram.",
