Abstract
A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, illuminating a surface with a light source, capturing an image of a shadow cast by the polymer film on the surface while the polymer film is between the light source and the surface, calculating a frequency spectrum of at least a portion of the captured image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the frequency spectrum.
