MUTUAL INSTRUMENT DEVELOPMENT FOR LARGE TELESCOPES

我们一直在这项资助下合作开发前沿观测仪器及其控制软件和数据分析和存档系统，以减少和存档这些仪器所采集的数据，以便充分利用世界上性能最高的大型望远镜。由于大型望远镜之一的斯巴鲁望远镜现在已经到了可以开始测试观测的阶段，本财政年度我们一直在用测试观测仪器进行测试观测，以检查望远镜各方面的性能。采用宽视场光学相机、红外相机和高速读出相机测量望远镜振动和大气湍流。我们通过测试观测确认，斯巴鲁望远镜满足其规格要求，在分辨率、图像质量、跟踪精度等方面表现优异。建立了观测程序和控制程序，表明望远镜控制系统软件具有良好的性能，可实现高效运行。通过测试观测收集了大气湍流的基本数据，并将用于分析自适应光学系统的参数，该系统补偿大气湍流引起的图像退化，以实现更高的分辨率观测。通过测试观测有了新的发现，进一步证明了斯巴鲁望远镜具有世界前沿性能的事实。

We have been making collaboration under this grant for developiong frontier observing instruments with their control software and data analysis and archive system for reducing and archiving data taken with such instruments, in order to make best use of the highest performance large telescopes in the world. Because Subaru telescope, one of such large telescopes, has now come to the state that we can start test observations, we have been carrying out test observations this fiscal year with test observing instruments to check various aspects of telescopeperformance. A wide field optical camera and an infrared camera were used with a high speed read-out camera to measure telescope vibration and atmospheric turbulence. We confirmed through the test observations that Subaru telescope satisfies its specifications and has excellent performance in its resolving power, image quality, tracking accuracy, and so on. Observing procedures and control sequences are being established, which suggests that the telescope controlsystem software also has satisfactory performance for efficient operation. Basic data for atmospheric turbulence was collected through the test observations, and will be used for analysis to derive parameters for the adaptive optics system, which compensates image degradation due to atmospheric turbulence to allow higher resolving power observations. New discoveries have been made through the test observations, which strengthens the fact that Subaru telescope has world frontier performance.
