Paper Abstract

A new optical method for measuring the diameter of transparent filaments has been developed. It is based on determining the dimension of a sharp shadow image of the filament on a photo-detector. The influence of transmitted light is diminished by spatial filtering. The resolution is better than 1% for diameters down to 10 μm.
