Abstract
Official abstract text for this publication.
A vari-focal fluidic lens is provided. The fluidic lens includes a frame, an first membrane, a second membrane, and an optical fluid. The frame defines an inner space of the fluidic lens including a driving portion and a lens portion that are connected to each other. The elastic membrane is attached to one side of the frame to cover at least the lens portion. The second membrane is attached to an opposite side of the frame to cover at least the driving portion and is deformable in response to temperature change to vary a volume of the inner space. Optical fluid is contained in the inner space.
