摘要

The measuring system based on photon correlation spectroscopy is improved through several means. The distribution of nanometer particle's sizes measured by new systems is more stable and accurate. All of the experiments are done in an ultra-clean chamber. The temperature is controlled and changes from about 13 degrees centigrade to 22 degrees centigrade. Fibers with different core diameters are used to transmit scattering light. The "Y" type fibers with different core diameters are used to transmit both the incident laser and the scattering light. The microscope objectives with different numerical apertures are used to collect and couple the scattering light into fiber. The software of real time correlation is tried to be used in the measuring system and it is compared with the static correlation. The Labview is used to integrate the software of correlation and inverse algorithms of nanometer particle sizes. Influences of incident laser with different power and mode are analyzed.
