ABSTRACT:
Disclosed is a monitoring system and method of monitoring optical-fiber drawing systems. The scattering monitor includes: a scattering monitor housing provided on a path drawing an optical fiber and having holes aligned on the upper and lower ends of the scattering monitor housing with the optical fiber passing there-through; a reflecting plate surrounding the optical fiber in the scattering monitor housing; a light condenser for converging light reflected from the reflecting plate; and, a light detector for detecting converged light and generating a corresponding electrical signal.
