碩士 === 國立中興大學 === 精密工程學系所 === 100 === The research goal is to develop a bionic compound eye with curved microlens array. In this study, lithography and electroforming technology were used to fabricate planar microlens array mold. The PDMS (Polydimethylsiloxane) was the material for replicating planner microlens array membrane. To make a top hemispheres opening chamber which was replicated from a acrylic mold, then the planar microlens array membrane was placed on the chamber. The syringe was used to draw the air which is in the chamber. The planer microlens array membrane was deformed by pressure difference and it became the curved microlens array. It was combined with the CMOS image sensor to capture images. The achieved FOV of the system is 112°. This study successfully fabricated the apposition microlens array, which has the advantages of simple process, the mold can be reused for rapid forming.
