Aeonium nobile SAP holograms

We report new material to record holographic images in an organic polymer of sap plant (Aeonium Nobile) by conventional microlithographic techniques with ultraviolet light. The information of the mask is transferred like a polymerized regions modulation. It is a phase modulation by means of refraction index. The material is developed by itself by means of the well-known physical-chemical reaction of cured.
