  • System and method for measuring the permeability of a material
    Patent number: 7224447
    Abstract: A system for measuring the permeability of a material includes a light source for illuminating the material, and a stray light sensor for detecting stray light traveling through the material from the light source and outputting a stray light signal indicative of the stray light detected. The system further includes a direct light sensor for detecting direct light traveling through holes in the material from the light source and outputting a direct light signal indicative of the direct light detected. Finally, the system includes a digital processing device for receiving the stray light and direct light signals and calculating the permeability of the material.
