碩士 === 國立中興大學 === 精密工程學系所 === 97 === The research is to develop about method with low driving voltage for variable focus liquid lens module, using milling machine to process the acrylic chamber with variable focus liquid lens module, and using lithography to fabricate photoresist mold. Then,to deposit sliver on the structure and to mold membrane with PDMS. The molded structure forms the transparent membrane and PDMS membrane is combined with acrylic chamber. Finally, using PZT actuator to drive PDMS membrane and varying the curvature of PDMS membrane to achieve the zoom through the various pressure of chamber. The variable focus liquid lens with 3 mm in diameter, with the focus turning range from 54.89~9.02 mm, and with driving voltage 10~100V. This study is to focus on replacing PDMS with the acrylic which has the good rigidity for lens chamber. The purpose is to decrease the loss of driving PZT actuator. Different from the circumscribed driving way, it not only decreases the space but also integrates on optics lens conveniently. It can reduce the liquid leak when connecting the chink and reduce the cost efficiently to achieve the quantity of output.
