Recent advances in materials science and unconventional computing have enhanced a growing interest in the development of "intelligent matter", materials that integrate sens- ing, memory, and adaptive response within their physical structure. These systems aim to implement computational functions directly at the matter level, enabling distributed, low-power information processing without relying on external control or digital architectures. Within this emerging paradigm, light-responsive materials, especially azobenzene-based polymers, have shown great promise due to their intrinsic light-triggered molecular dynamics. This thesis investigates the azopolymer PAZO as a candidate for implementing elementary visual functionalities directly in matter. Through optical stimulation, PAZO films exhibit birefringence with tunable dynamics, governed by molecular reorientation and relaxation processes.
