Holographic patterning of acrylamide-based photopolymer surface.
The patterning of an acrylamide-based photopolymer surface by holographic recording is studied. The patterns are induced by light alone and no post-processing is required. Periodic surface modulation is observed in addition to a volume phase grating. An investigation has been carried out using white light interferometry into the dependence of the amplitude of the photo induced surface relief mo...
متن کاملRaman spectroscopy for the characterization of the polymerization rate in an acrylamide-based photopolymer.
Investigations of polymerization rates in an acrylamide-based photopolymer are presented. The polymerization rate for acrylamide and methylenebisacrylamide was determined by monitoring the changes in the characteristic vibrational peaks at 1284 and 1607 cm(-1) corresponding to the bending mode of the CH bond and CC double bonds of acrylamide and in the characteristic peak at 1629 cm(-1) corresp...
متن کاملStudy of reflection gratings recorded in polyvinyl alcohol/acrylamide-based photopolymer.
High-spatial-frequency fringes associated with reflection holographic optical elements are difficult to obtain with currently available recording materials. In this work, holographic reflection gratings were stored in a polyvinyl alcohol/acrylamide photopolymer. This material is formed of acrylamide photopolymer, which is considered interesting material for optical storage applications such as ...
متن کاملEdge-enhanced imaging with polyvinyl alcohol/acrylamide photopolymer gratings.
We demonstrate edge-enhanced imaging produced by volume phase gratings recorded on a polyvinyl alcohol/acrylamide photopolymer. Bragg diffraction, exhibited by volume gratings, modifies the impulse response of the imaging system, facilitating spatial filtering operations with no need for a physical Fourier plane. We demonstrate that Kogelnik's coupled-wave theory can be used to calculate the tr...
متن کاملStudy of the shrinkage caused by holographic grating formation in acrylamide based photopolymer film.
We study the shrinkage in acrylamide based photopolymer by measuring the Bragg detuning of transmission diffraction gratings recorded at different slant angles and at different intensities for a range of spatial frequencies. Transmission diffraction gratings of spatial frequencies 500, 1000, 1500 and 2000 lines/mm were recorded in an acrylamide based photopolymer film having 60 ± 5 μm thickness...
