This paper applies the Mueller scattering matrix for cylindrical quartz fibers to determine the buildup of thin water sheaths on the fibers as a function of humidity. We created four quartz fibers of various sizes and used a controlled-humidity environment to establish a relationship between relative humidity and water sheath thickness. We determined the thickness by measuring a particular Mueller scattering matrix at a single angle and relating changes in polarized light scattering Sij directly to the thickness of the water layer. We report an accelerated growth of a water sheath on quartz fibers at humidities above 90 and an irregular relationship between the fiber radius and the maximum size for a water layer. MM
