The concept design for a laboratory based telescope emulator for the Giant Magellan Telescope (GMT) is described here. The Giant Magellan Telescope has a primary mirror comprised of 7 segments, and a secondary mirror with matching segmentation. The phasing of the GMT is a complex problem; a phasing testbed, Pocket-GMT, has been designed by a group within the Research School of Astronomy and Astrophysics at the Australian National University for the Giant Magellan Telescope Corporation. Pocket-GMT uses a novel technique to split the bending modes between a piston/tip-tilt surface and a deformable mirror. Pocket-GMT will demonstrate successful phasing of an optical miniature GMT by the planned prototype wavefront sensing systems. By reproducing the optical characteristics of the GMT on a small scale, Pocket-GMT will reduce the risk associated with the phasing system and provide a platform to test the telescopeFLs instrumentation prior to commissioning.

Pocket-GMT 的设计：巨型麦哲伦望远镜的光学仿真

此处描述了用于巨型麦哲伦望远镜 (GMT) 的基于实验室的望远镜模拟器的概念设计。巨型麦哲伦望远镜有一个由 7 个分段组成的主镜和一个具有匹配分段的副镜。GMT 的相位调整是一个复杂的问题；澳大利亚国立大学天文和天体物理学研究学院的一个小组为巨型麦哲伦望远镜公司设计了一个定相测试台 Pocket-GMT。Pocket-GMT 使用一种新技术在活塞/尖端倾斜表面和可变形反射镜之间分离弯曲模式。Pocket-GMT 将展示计划中的原型波前传感系统对光学微型 GMT 的成功定相。通过小规模再现 GMT 的光学特性，
