2. Towards Elucidating Effects of Multiple Light Scattering
　　Studies of light scattering from fluctuating random media have been the subject of great interest in a wide range of laser metrology, such as environmental remote sensing, nondestructive testing for a material surfaces and noninvasive sensing for biological tissue. In particular elucidation of multiple scattering effects is essential in connection with, for example, the improvement of the accuracy in measurements and the development of a novel measurement technology.
　　In this project we established an analytical method of describing multiple light scattering from random media and then studied the unsolved problem of changes in the spectrum of light induced by multiple scattering. As a result, the physical origin of such spectral changes has been shown to be attributed to synergistic effects of temporal and spatial fluctuations of the medium. It has also been shown that this phenomenon may be utilized as a novel principle of laser metrology.
