提出了一种用于自适应光学的小型变形镜的替代方法。建立了一个两英寸的反射镜的原型，该反射镜由覆盖有永磁体矩阵和微线圈阵列的薄聚合物膜组成。几个互补的建模工具被用来研究该设备的行为。有前途的第一个结果显示，高达20 /spl mu/m，良好的线性度和带宽为200 Hz的定期变形。这种新技术应该能够用更小、更轻的集成反射镜实现更高的分辨率。
An alternative approach to compact deformable mirrors for adaptive optics is developed. A prototype of a two inch mirror composed of a thin polymer membrane covered with a matrix of permanent magnets and an array of microcoils was built. Several complementary modelling tools were used to study the behaviour of the device. Promising first results show regular deformations of up to 20 /spl mu/m, a good linearity and a bandwith of 200 Hz. This novel technology should enable higher resolution with smaller, lighter integrated mirrors.
