| Popis: | 103 Diacrylate Polymer(RM257, RM82) is main chain with high molecular liquid crystal, and it’s light sensitivity material. While the material being made into thin film, it can record optical data by polymerization. Based on our past research, high molecular liquid crystal thin film which is illuminated by He-Ne laser on non-primary absorbed wave range can lead to polymerization. We use He-Ne laser as a light source and modulate it forming double beam interference optical film to illuminate high molecular liquid crystal thin film. Due to constructive and destructive interference, there’s corresponding one dimensional palisade structure on sample. Optical image of RM82 thin film illuminated by interference optical film was not proper. As a result, we use He-Ne laser interference with scheduling temperature program to illuminate RM82, discussing the relationship with scheduling temperature program and result of polymerization of RM82. We use non-coplanary triple He-Ne laser beam to modulate interference optical film with scheduling temperature program, and then make RM257、RM82 thin film being illuminated. In the end, We discuss how two dimensional periodical energy distribution of triple He-Ne laser beam to cause different molecular structure on high molecular liquid crystal thin film and impact of light modulation. |
