Abstract
In order to make it possible to measure the light absorption coefficient of various sorts of substances contained in a light scattering material with a high precision, the wavelength of light transmitted through the light scattering material is varied and the coefficient of light absorption is calculated, starting from a ratio of variations in the intensity of the transmitted light to variations in the wavelength.
