主动光学:具有最少数量致动器的可变形反射镜

Active optics: deformable mirrors with a minimum number of actuators

Marie Laslandes, Emmanuel Hugot, Marc Ferrari

摘要:

提出了两种补偿一阶光学像差的变形镜概念。变形系统的设计使用弹性理论和有限元分析,以尽量减少致动器的数量。从仪器规格开始,我们解释了设计专用变形镜的方法。这里提出的工作导致纠正设备优化的特定功能。可变离轴抛物面透镜的概念是一个3执行器,3模式系统能够产生独立的焦点,散光和昏迷。具有单个致动器的校正优化镜是能够产生给定的光学像差组合的单致动器系统。

英文摘要:

We present two concepts of deformable mirror to compensate for first order optical aberrations. Deformation systems are designed using both elasticity theory and Finite Element Analysis in order to minimize the number of actuators. Starting from instrument specifications, we explain the methodology to design dedicated deformable mirrors. The work presented here leads to correcting devices optimized for specific functions. The Variable Off-Axis paraboLA concept is a 3-actuators, 3-modes system able to generate independently Focus, Astigmatism and Coma. The Correcting Optimized Mirror with a Single Actuator is a 1-actuator system able to generate a given combination of optical aberrations.
