Abstract
A variable aperture assembly is provided. For example, a variable aperture assembly comprises a piezoelectric annular bending disc, a polymer disc coupled to the bending disc, a cover glass coupled to the polymer disc, and a light absorptive fluid contained in a space between the polymer disc and the cover glass. The bending disc is selectively deformable when a voltage is applied. The polymer disc has a convex portion curved toward the cover glass. An area of contact between the convex portion and the cover glass defines an optical aperture. A size of the optical aperture is controlled by controlling a size of the area of contact between the convex portion and the cover glass. The size of the area of contact between the convex portion and the cover glass is controlled by controlling the voltage applied to the bending disc.
