Abstract
A method for using laser Doppler velocimetry to determine the mass flux (mass per area per time) of a polymer fiber stream without interfering with the flow of the fiber stream wherein a factor is determined for converting laser data rate information into stream flow mass flux values and to determine the diameter of a filament by measuring filament velocity without interfering with the flow of the filament.
