| Popis: | 96 This research is to develop a stress analysis method for a novel zoom lens system with a soft polymer materials, PDMS(Polydimethyslsiloxane). This analysis method can predict deformation of elastmer and effective focal length (EFL) of soft PDMS lens after activating by pneumatic pressure. In order to construct the numerical stress analysis method, a detailed characterization of PDMS property is required. The research first focuses on the test of mechanical and optical properties of PDMS, including Young’s modulus, refractive index and Abbe number. Then the lens profile and soft zoom lens system can be designed. Deformation of PDMS lens can by analyzed by ANSYS with materials parameters and lens design model. Finally, the soft PDMS lens is fabricated and assembled into zoom system to measure the deformation and EFL. From experimental results, the error of deformation between simulation and experiments is below 15% and the EFL of soft zoom lens with PDMS plano-convex lens can change from 63.46 mm to 112.87mm as the pressure activated from 0 to 0.0125MPa. Future work can integrate the design of soft PDMS lens into the lens of mobile phones and cameras, as well as the imagine system of minis devices. |
