A technique for the real‐time visualization of material line movement during transparent gel deformation was developed based on caged photo‐activated fluorophores covalently attached to the gel network. It is used to quantitatively monitor the swelling of sodium polyacrylate and poly(acrylamide‐sodium acrylate) gels in quasi two‐dimensional constrained geometries. The experimentally obtained profiles for the Finger deformation tensor and the polymer concentration are compared with transient simulations of a model of transport in polyelectrolyte gels.
