Investigation of the dynamic response performance for the liquid-filled variable focus lens

摘要

With the purpose of designing a liquid-filled variable focus lens with a large optical aperture and high-speed performance, an investigation research and a series of comparison experiments were conducted. One of the foundings is that the eigenfrequencies of the actuation unit and the lens' dynamic surface profile will become the critical parameters when the lens aperture becomes large. Mechanics analysis of the deformation was studied, and a series of the lens prototype was built.
