Abstract:
1. A method for measuring a scattering medium performed by an apparatus including a light detector, a signal processing unit, and a waveform processing unit, the method comprising: a light incident step in which pulse light with a predetermined wavelength is made incident within a light incident arrangement from a light incident position to a scattering medium which is a measurement object and a scattering medium for reference; a light detecting step in which the pulse light made incident in the light incident step and transmitted inside each of the scattering media is detected by the light detector at a light detecting position to acquire a light detection signal; a signal processing step in which a measurement waveform showing temporal change in light intensity is acquired by the signal processing unit on the basis of the light detection signal detected by the light detector in the light detecting step; a waveform processing step in which when the measurement waveform of the scattering medium which is the measurement object acquired by the signal processing unit in the signal processing step is given as P  and an internal information calculation step in which on the basis of the theoretical waveform of the scattering medium which is the measurement object expressed by the function having the specified parameter in the waveform processing step, calculation is made by the waveform processing unit for the internal information of the scattering medium which is the measurement object.
