摘要：
We propose measuring the size of particles suspended in a liquid by light beating spectroscopy of scattered light using an optical fiber probe inserted into a medium and consisting of three multimode optical fibers. One of them is used to transmit light, the other two - to transmit scattered light to a unit providing its spatial coherence and further to a photodetector. In very turbid media, the multiple-to-single light-scattering spectral line width ratio is determined by the ratio of line widths in two collecting optical fibers. Then the particle size is determined by the spectrum of multiple rather than single scattering.
