Abstract
Abstract The invention relates to a system and a process for measuring fiberglass. The process consists in directing a beam of radiation into the fiberglass, the beam including at least first, second and third wavelengths of radiation all generated by the same source (10), measuring the intensity of the beam at said first, second and third wavelengths after the beam has been trans- mittted through the fiberglass (18), and thus determining the property of the fiberglass (18) based upon the measured intensities of said three wavelengths. Application to the determination of the degree of one of a fiberglass.
