ABSTRACT:
Light having a predetermined wavelength and various incident angle components to be incident on a surface of a scattering medium to generate an equivalent point light source or a group of equivalent point light sources near or on the surface of the scattering medium, and light diffused during propagation in the scattering medium is detected outside, and considering isotropic light from the equivalent light sources is immediately diffused, the optically detected signal is processed to detect a predetermined parameter which is primary information and this predetermined parameter is processed to measure internal information which is secondary information in the scattering medium with high accuracy.
