In this paper we present a Modal Deformable Mirror (MDM) based on the continuous voltage distribution over a resistive layer. This Deformable Mirror (DM) can correct spherical aberration and coma in addition to the low order aberrations (defocus and astigmatism) using just nine contacts thus limiting the requirements of high voltage lines with respect to state of the art devices. We demonstrate the advantages of this technology presenting a mathematical description of the mirror, an experimental characterization and a comparison with discrete actuator DMs. In order to demonstrate the effectiveness of this design in sensorless applications we present the experimental results for image sharpening optimization. The easiness of use suggests that it can be useful for many applications from imaging systems to laser process optimization.
