提出了一种基于阻层上连续电压分布的模变形镜(MDM)。除了低阶像差(散焦和散光)之外，这种可变形反射镜(DM)仅使用9个触点就可以校正球差和彗差，从而限制了高压线路对最先进设备的要求。我们展示了这种技术的优点，给出了反射镜的数学描述，实验表征，并与离散致动器DM进行了比较。为了验证该设计在无传感器应用中的有效性，我们给出了图像锐化优化的实验结果。它的易用性表明，它可用于从成像系统到激光工艺优化的许多应用。
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.
