我们展示了低成本光学终端 (LCOT) 的自适应光学 (AO) 组件的初步实验室测试结果，LCOT 是戈达德太空飞行中心开发的灵活通信地面终端。 LCOT 将于 2023 年接受首次测试。 该终端包括一台700毫米商用望远镜、1550纳米接收仪器和上行传输系统。 解调相干格式需要 AO 来校正湍流效应并允许耦合到单模光纤中。 通用原子公司于 2021 年 9 月将该系统交付给戈达德，工程师们在那里评估了性能。我们描述了实验室测试、湍流相位板设计、结果以及安装在 LCOT 上时的 AO 现场测试计划。
We present the initial laboratory test results of the adaptive optics (AO) subassembly for the Low-Cost Optical Terminal (LCOT), a flexible communications ground terminal developed by Goddard Space Flight Center. LCOT will receive first light in 2023 testing. This terminal includes a 700mm commercial telescope, 1550nm receive instruments, and uplink transmit systems. Demodulating coherent formats requires AO to correct turbulence effects and allow coupling into single-mode fiber. General Atomics delivered the system to Goddard in September 2021, where engineers have evaluated performance. We describe laboratory testing, turbulence phase plate design, results, and AO field testing plans when installed on LCOT.
