应科院SST-2 M（Astrofisica con Specchi a Tecnologia Replicante Italiana）是切伦科夫望远镜阵列的小型望远镜原型。它将在成像大气切伦科夫望远镜上应用双镜配置。主镜（直径4.3米）的18个部分配备了一个主动光学系统，能够在望远镜回转期间进行光学重新对准。次镜（直径1.8米）可以沿沿着三个自由度移动，以执行聚焦和倾斜校正。我们描述了用于预测系统性能的运动学模型以及将用于光学控制的硬件和软件设计解决方案。
ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) SST-2M is an end-to-end prototype of Small Size class of Telescope for the Cherenkov Telescope Array. It will apply a dual mirror configuration to Imaging Atmospheric Cherenkov Telescopes. The 18 segments composing the primary mirror (diameter 4.3 m) are equipped with an active optics system enabling optical re-alignment during telescope slew. The secondary mirror (diameter 1.8 m) can be moved along three degrees of freedom to perform focus and tilt corrections. We describe the kinematic model used to predict the system performance as well as the hardware and software design solution that will be implemented for optics control.
