Paper Abstract

We developed a new type of optical lens device that can change its curvature like crystalline lens in human eye. The curvature changing capability of the lens allows for a tremendous tuning range in its optical power and subsequently enables miniaturized imaging systems that can perform autofocus, optical zoom, and other advanced functions. In this paper, we study the physical properties of bio-inspired fluidic lenses and demonstrate the optical functionality through miniaturized optical systems constructed with such lenses. We report an auto-focusing optical system that can turn from a camera to a microscope, and demonstrate more than 4X optical zoom with a very short total track length. Finally, we demonstrate the benefits of fluidic lens zoom camera through minimally invasive gallbladder removal surgery.
