Abstract
A flexible optic or optical system is deformed using a non-overlapping iris or any of several deformable ring or polygon shapes. In some examples, the deformation of the flexible optic is controlled by one or more actuators comprising a shape memory material. The flexible optic may be used in, e.g. a bar code reader or imager.
