Abstract: A method for measuring a property of a fiber, such as flexibility, collapsibility and moment of inertia. A fiber is wetted and deformed in its wet state, and an optical section image of the deformed fiber is taken. A measurement is made on the image and the desired property is calculated using the measurement.
