Abstract

In this work,a new approach to measuring the volume scattering function of dual microspheres in a wide angular range is developed.The polydimethylsiloxane microfluidic chip is designed by the simulation of COMSOL,and is supposed to capture dual particles efficiently.After refractive index matching of microfluidic and the chip,this system can measure scattering light from 1° to 170° in a continuous way.Standard polystyrene particles with a size of 23.75 μm,31.10 μm,and 40.01 μm are used as experimental samples.The high stability of the capture and the good repeatability of the experiment makes it having great potential in the study of the volume scattering function.

Key words
