Paper Abstract

The ability to accurately measure the particle sizes distribution of particle suspensions and dispersions has proven to be crucial for ensuring the success of a wide process materials and final products. We propose tow optical fiber sensors that exploit light intensity modulation in optical fibers. One of them is constructed in a typical reflection-sensing configuration but it sues the backscattering effect on particles in suspension. The other one is lens deflecting the light away from incident beam. Furthermore, we have presented the theoretical framework concerning the light scattering on dielectric spheres and colloidal aggregates. The relevant experimental data are also shown in order to prove the sensors reliability.
