Paper Abstract
Recently the possibility to record phase diffractive optical elements (DOEs) onto photopolymers has been explored. Two
of their properties when they are illuminated are useful to this goal: the relief surface changes and the refractive index
modifications. The recording intensity distribution with a sinusoidal profile is the easiest profile to record in a
holographic recording material, i.e. it can be obtained by the simple interference of two plane wave beams or
alternatively using a spatial light modulator. This second method is more flexible and opens the possibility to record a
wide range of diffractive elements such as binary, blazed gratings, diffractive lenses, etc. Sharp profiles may as well be
recorded. In general they present a clear smoothing of the edges due to various reasons: the cut-off frequency (a low pass
filtering) of the optical system, quality of the spatial light modulation, inhibition period, finite size of polymer chains,
monomer diffusion, and non-linearities in the recording process. In this work we have analyzed the importance of some
of these aspects of the photopolymer and the experimental set-up in order to record high quality DOEs. The
photopolymer analyzed is based on polyvinylalcohol/acrylamide. To achieve this goal we have used a diffusion model to
simulate the DOE’s recording with different recording intensities distributions.
