Reflection of particles

Fig. 15. Theoretical calculations of the reflection of energy and the reflection of particles for H, He, and T from copper. Calculations based on computer simulation. Normal incidence. R /Rn is the average fractional energy of a reflected particle. (From Ref. )...

Optic fiber sensors used in multiphase flows are based on the reflectivity of particles against incident light. This kind of optic fiber sensor, the so-called intensity modulated optic fiber sensor, is simple in structure, easy in operation and high in sensitivity.
