30米望远镜（TMT）是下一代巨型分段反射镜望远镜，将具有前所未有的天文科学能力。由于自适应光学的使用大大提高了科学生产力，TMT科学团队决定在所有红外仪器上植入自适应光学。我们提出的自适应光学系统的红外多目标摄谱仪，IRMOS和报告的设计概念和建筑方案的可行性研究结果。IRMOS仪器的目的是产生分布在5弧分视场内的多达20个物体的积分场谱。IRMOS自适应光学设计的独特之处在于，它将使用多个激光导航星来重建大气体积断层摄影，然后独立地对每个科学方向应用AO校正。通过使用微机电系统（MEMS）可变形反射镜，使得这种方案在技术上可行并且具有成本效益。
The Thirty Meter Telescope (TMT), the next generation giant segmented mirror telescope, will have unprecedented astronomical science capability. Since science productivity is greatly enhanced through the use of adaptive optics, the TMT science team has decided that adaptive optics should be implanted on all the IR instruments. We present the results of a feasibility study for the adaptive optics systems on the infrared multi-object spectrograph, IRMOS and report on the design concepts and architectural options. The IRMOS instrument is intended to produce integral field spectra of up to 20 objects distributed over a 5 arcminute field of regard. The IRMOS adaptive optics design is unique in that it will use multiple laser guidestars to reconstruct the atmospheric volume tomographically, then apply AO correction for each science direction independently. Such a scheme is made technically feasible and cost effective through the use of micro-electromechanical system (MEMS) deformable mirrors.
