Real Time Shrinkage Studies in Photopolymer Films Using Holographic Interferometry
Moothanchery, Mohesh; Naydenova, Izabela; Bavigadda, Viswanath; Martin, Suzanne; Toal, Vincent
Polymerisation induced shrinkage is one of the main reasons why photopolymer materials are not more widely used for holographic applications. The aim of this study is to evaluate the shrinkage in an acrylamide photopolymer layer during holographic recording using holographic interferometry. Shrinkage in photopolymer layers can be measured by real time capture of holographic interferograms during holographic recording. Interferograms were captured using a CMOS camera at regular intervals. The optical path length change and hence the shrinkage were determined from the captured fringe patterns. It was observed that the photopolymer layer shrinkage is in the order of 3.5%.
