Scattered light intensity

WebDynamic light scattering DLS measures the correlation function of intensity fluctuations. This can then be mathematically converted into an intensity size distribution, and from there to a volume ... WebDec 16, 2013 · Prior research has shown that intensity modulation (<100 MHz) can be used to “wash-out” the backscatter, resulting in better discrimination of the target and higher contrast. We show that the higher modulation frequencies (>100 MHz) can be also used to suppress forward scattered light, thereby increasing spatial resolution.
