This work investigates improving the imaging quality of membrane mirrors using multiple active fiber composite (AFC) actuators. It is demonstrated in the literature that the structural characteristics of a circular membrane lens can be used advantageously to eliminate nearly 100% of a 5th order image aberration. The approach here is to study the transverse vibration of a membrane mirror strip augmented with two micro fiber composite (MFC) bimorphs. Each bimorph is placed near one of the ends of the strip. One of the bimorphs will be excited in phase, causing a local tension in the strip, whereas the other will be excited out of phase, causing a local bending moment. The finite element method (FEM) is used to present the system mathematically. The advantage of the FEM is evident; it easily handles the physical non-uniformities caused by the augmentation of the actuators. To verify the presented model, a constant in-phase voltage is supplied to one of the MFCs. Hence, the local tension induced by this MFC bimorph is constant, and the resulting model is linear. A frequency response is obtained from the FEM model and through an experiment. The FEM and experimental results are in agreement. Additionally, results show that the local tension changes the structural properties of the membrane strip. The proposed approach can be extended to the two dimensional case with the promise of contributing to the elimination of image aberrations.
