Abstract
A method and apparatus for determining surface molecular orientation and related properties of an opaque polymeric sheet relies on the detection of relative intensity of spectral reflectance in at least one polarized beam reflected from the surface of the sheet rather than transmitted therethrough. The relative intensity is affected by the preferential orientation of the polymeric chains. The method is fast and can be applied on-line at a speed of the running sheet as high as 1000 m/s.
