PROBLEM TO BE SOLVED: To provide a device and a method that enable precise calculation of a conversion scattering coefficient and an absorption coefficient.SOLUTION: A scattering absorber measuring device 1A comprises: a light source part 31 that emits multiple light pulses P(n) mutually differing in wavelength to a scattering absorber B; a light detection part 41 that detects the respective light pulses P(n) propagating through the inside of the scattering absorber B; and an operation part 5 that calculates a conversion scattering coefficient and an absorption coefficient by a time-resolved spectroscopic measurement method. The calculation part 5 preliminarily has data D2 about a conversion scattering coefficient ratio between the wavelengths of the light pulses P(n), and calculates the conversion scattering coefficient and the absorption coefficient by collectively fitting time-resolved measurement profiles of multiple wavelengths to a solution for a light diffusion equation, on the assumption that the conversion scattering coefficient for each wavelength is subjected to the conversion scattering coefficient ratio. |
