Abstract

A simple and sensitive method to determine tissue scattering dynamic parameters is presented. A mode-locked laser is used as an impulse radiation source. Amplitude and number of generation modes are connected to duration and shape of the pulse via Fourier transformation. Scattered optical signal, containing multiple scattering information, is broadened in comparison with incident pulse. Analysis of the output signal is performed by measuring spectral components on the frequencies of mode beating. This approach allows us to increase sensitivity.
