Abstract
The volume of a photopolymerizable medium may be changed after monomer is converted into polymer. One has not yet precise method for measuring a volume change when a photopolymerization reaction occurs in a film. This paper proposes a holographic method for measuring the volume change (that is the thickness change) of a photopolymerizable film. The method relys on the fact that the volume change can cause a holographic grating period change and result in peak replay wavelength shifts. The volume change can be obtained from the Bragg law, compared the experimental result with the theoretical calculated value.
