Low density substrate materials based on silicon carbide variants may have the potential for use as a shell material for large deformable mirrors. Instrumentation optics for ELTs will also utilise optics of significant size, and will be mass-sensitive. By taking existing materials and components and modifying them to meet the demands of European ELT requirements we will demonstrate a cost-effective and risk-mitigating technological advantage. We will demonstrate that 'sandwiching' silicon carbide in a material such as silicon dioxide will lead to a technological advantage to a novel concept of large deformable mirror shell. We will analyse the mechanical integrity for the application and demonstrate control of the surface position and deformation using existing Piezo actuators modified with a surface sensing transducer.

基于碳化硅变体的低密度衬底材料可能具有用作大型可变形反射镜的外壳材料的潜力。用于ELT的仪器光学器件也将使用大尺寸的光学器件，并且将是质量敏感的。通过采用现有材料和组件并对其进行修改以满足欧洲ELT要求，我们将展示具有成本效益和降低风险的技术优势。我们将证明，“镶嵌”碳化硅的材料，如二氧化硅将导致一个新的概念，大变形镜壳的技术优势。我们将分析的应用程序的机械完整性，并证明控制的表面位置和变形使用现有的压电致动器与表面传感传感器修改。
