IRTF-ASM-1自2024年首次光以来运行良好，该自适应次镜（ASM）主要用于在NASA红外望远镜设施（IRTF）上演示新型混合可变磁阻致动器技术。由于其物理稳健性以及此前ASM灵敏度提升的演示，我们希望利用它每晚优化望远镜图像质量，这将直接惠及科学观测。但IRTF目前缺乏自适应光学专业人员，因此我们正开发该系统以实现最小人工干预使用。我们展示了使用单共轭设施2×2夏克-哈特曼波前传感器Felix开发IRTF-ASM-1主动光学模式软件的进展，还介绍了消除Felix与科学仪器之间低阶、大幅值非共光路像差的技术。
英文摘要
IRTF-ASM-1 has been functioning well since its first light in 2024. This adaptive secondary mirror (ASM) was primarily developed to be an on-sky demonstration of the new hybrid variable reluctance actuator technology at the NASA Infrared Telescope Facility (IRTF). However, due to its physical robustness and our previous demonstrations of sensitivity enhancements with the ASM, we are interested in using it to optimize telescope image quality on a nightly basis. This will directly benefit science observations. However, as IRTF does not currently have adaptive optics expertise, we have been developing the system to be used with minimal human intervention. We present our progress in developing software for active optics mode with IRTF-ASM-1 using the single conjugate, facility 2x2 Shack-Hartmann wavefront sensor Felix. We also present techniques for removing low-order, large amplitude non-common path aberrations between Felix and our science instruments.
