Abstract
In this work, we have studied the propagation of ultrasound modulation scattering signal in multi-layer scattering media. The relations to the modulation light intensity and its modulation depth contributed by the thickness, absorption coefficient and scattering coefficient of two- and three- layered scattering media are figured out. The results of Monte Carlo simulation and experiments show that the modulated depth of the modulated light is only dependent on optical and ultrasonic properties of scattering media within the ultrasound zoom, and doesn't change in the propagation in multi-layer scattering media. And the modulated depth is a key factor in ultrasound-modulated optical tomography.
