PROBLEM TO BE SOLVED: To provide a method for imaging the spatial distribution of absorption substance concentration in a scattering body by light. SOLUTION: An imaging method consists of a step 1 that generates a measurement-value matrix Y according to measured detection light intensity, a step 2 that obtains the absorbance coefficient of an absorption substance inside a scattering body and light path data for allowing light in the scattering body being obtained by simulating the scattering body where the absorption substance does not exist to pass by the Monte-Carlo method and generates a space distribution matrix A of an average light path length according to the light pat data, a step 3 that derives an unknown matrix X according to the matrixes Y and A, and a step 4 that obtains absorption substance concentration inside a specimen according to the obtained unknown matrix X and displays the spatial distribution. When the light path is calculated by the Monte-Carlo method before the processing of the step 2 is started, and the light path data is stored, the stored light path data is used, thus accurately and quickly imaging the three-dimensional distribution of the absorption substance concentration with a high resolution.
