  • Publication number: 20240110833
    Abstract: A dispersion measurement apparatus includes a pulse forming unit, a correlation optical system, a beam splitter, an operation unit, an imaging unit, a spatial filter unit, and a photodetector. The pulse forming unit forms a light pulse train including light pulses having time differences and different center wavelengths. The beam splitter branches the light pulse train passed through a measurement object. The imaging unit disperses one light pulse train and images each light pulse. The spatial filter unit extracts light of a partial region of the other light pulse train. The correlation optical system outputs correlation light including a cross-correlation or an autocorrelation of the extracted light. The photodetector detects a temporal waveform of the correlation light. The operation unit estimates a wavelength dispersion amount in the measurement object based on a feature value of the temporal waveform.
