| Abstract: | Different aperture fiber were applied for transmission of laser and scattered photons, different aperture y-type fiber were used for transmission of incident and scattered light synchronously. Based on photon correlation spectroscopy the nanometer particle measuring system was designed. Besides, the af- fects of fiber core diameter, microscope objectives numerical aperture, temperature and scattering angle were discussed. Experiments show that it is accurate and stable for nano-particle size distribution meas- urement, all experiments were finished in super clean room,in which temperature was controlled at about 13-22 ℃. |
