Adaptive optical systems incorporate active components that compensate for wavefront aberrations introduced by optical defects. The increase in resolution is limited by the stroke of the adaptive components underlying actuating mechanism and the differential stroke of neighbouring actuators. Development of high-density nano-scale polypyrrole bilayer actuator arrays may deliver superior performance over conventional adaptive optics actuator technologies such as electrostatic electrodes or piezoelectric mirrors. This study establishes key performance requirements for adaptive optics systems and proposes a prototypical design of a novel deformable mirror based on conductive polymers. The associated fabrication methods are evaluated and critical technological barriers pertinent to future development are identified. The implications of this technology range from more powerful astronomical telescopes to improved retinal tissue diagnosis.
