Disclosed is a lens mechanism made of a flexible support with a lens
positioned on the support. A sensor is positioned below the lens so that
it senses photons passing through the lens. At least one actuator is
positioned around the lens such that a change in an electric charge on
the actuator causes the lens to move. In one embodiment, the lens moves
along its optical axis. In another embodiment, the lens moves so that its
optical axis tips from the original orientation. In yet another
embodiment, the lens moves due to a change in electric charge on an
electrostatic charge layer that is substantially coincident with the
lens. Embodiments of the invention can provide a dynamic actuator
mechanism for positioning a small lens.
