Abstract

There is provided detecting modification of optically active cellulose-based film. A method comprises controlling, by a processor, an optical position sensor device to capture data from a first diffraction response formed based on at least one modification of a first cellulose-based material part and a second diffraction response formed based on the at least one modification of a second cellulose-based material part; and determining, by the processor, a reading indicating the at least one modification based on the captured data.
