  • Scattering absorber measurement device and scattering absorber measurement method
    Patent number: 10422745
    Abstract: A scattering absorber measurement device includes a light source for outputting a plurality of light pulses having different wavelengths input to a scattering absorber, a photodetector for detecting each light pulse propagating inside the scattering absorber and output a detection signal, and a computation unit for calculating a reduced scattering coefficient and an absorption coefficient according to a time-resolved spectroscopic measurement method on the basis of the detection signal. The computation unit determines data related to a ratio of reduced scattering coefficients among wavelengths of the plurality of light pulses and calculates the reduced scattering coefficient and the absorption coefficient on the basis of a time-resolved measurement profile of each wavelength based on the detection signal and the data related to the ratio.
