Abstract

The invention relates to the analysis of defects in materials such as molten glass. According to the invention, the material passes by a monochrome beam the wavelength of which is below 3.times.10.sup.-6 m. The radiation is diffused by any defects present in the material. The analysis of the defects is conducted dependent on the position of the receiver detecting the diffused rays and on the shape of the signal received. The invention permits a continuous analysis of a flow of glass supplying a fiber-making machine.
