Aiming at the measurement of waveform and phase of optical pulses at 1.55 /spl mu/m, we construct an optical sampling system that enables sonogram characterization of optical pulses. We demonstrate the measurement of impulse response of an optical bandpass filter as a specific application of the system. The measured intensity and phase responses clearly show the effect of the dispersion slope of the filter.
