Paper Abstract

Low frequency microechography was a nondestructive technique, which could open a perspective to study photoimplementing optical properties in polymerizable materials. Indeed, this technique is particularly suitable for the characterization of crosslinking gradients in photopolymers and can visualize the local variation of mechanical properties. Two sets of samples were studied. The former which had been polymerized through a two level amplitude mask allowed to determine the resolution of the apparatus; the latter which were insulated through a apodizing filter with a radial density variation (in order to fabricate GRIN material) was an example of the study of mask pattern transfer into a polymer.
