| Abstract: | Dynamic light scattering (DLS) as an important technique has been intensively researched and applied widely for more than three decades. Specially, in recent years, much significant progress has been made, such as miniature laser light scattering instrumentation for particle size analysis, modification for the thermal blooming effect to yield the correct particle size, statistical processing of photons(SPP), one-beam or two-beam cross correlation technique and use of higher order photon correlation spectroscopy to recover asymmetric spectral lineshape. |

| Keywords: | particle sizing dynamic light scattering photon correlation spectroscopy |
