Photopolymerization, based on light-induced radical polymerization, is nowadays exploited in additive manufacturing (AM) technologies enabling to achieve high dimensional quality. The mechanical properties of the obtained material are heavily dependent chemistry photopolymer and way AM process performed. Here we study, through experiments theoretical modeling, how liquid crystal shutter (LCD) p...

A single beam one-step holographic interferometry method was developed to fabricate porous polymer structures with controllable pore size and location to produce compact graded photonic bandgap structures for linear variable optical filters. This technology is based on holographic polymer dispersed liquid crystal materials. By introducing a forced internal reflection, the optical reflection thr...

Studies of development kinetics in volume photopolymers typically use transmission holography to quantify the index distribution. This method has advantages including simplicity, quantitative index data and natural mapping onto theories using harmonic expansion of the material response. A particular disadvantage is that the low spatialfrequency response corresponding to the intensity of the wri...

The improvements made in diffusion models simulating phase image recording in photopolymers enable the optimization of a wide range of complex diffractive optical elements (DOEs), while the miniaturization of spatial light modulators makes it possible to generate both symmetric and non-symmetric DOEs. In addition, there is increasing interest in the design of new friendly recording materials. I...
