MUTUAL INSTRUMENT DEVELOPMENT FOR LARGE TELESCOPES

我们一直在利用这笔赠款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获得的数据，以便最好地利用世界上最高性能的大型望远镜。由于这种大型望远镜之一的斯巴鲁望远镜现在已经达到可以开始测试观测的状态，因此我们在本财政年度使用测试观测仪器进行了测试观测，以检查望远镜性能的各个方面。利用宽视场光学相机、红外相机和高速读出相机对望远镜振动和大气湍流进行了测量。通过试验观测，我们确认斯巴鲁望远镜满足其技术指标，在分辨力、像质、跟踪精度等方面具有优异的性能，并正在建立观测程序和控制序列，这表明望远镜控制系统软件也具有令人满意的性能，能够高效运行。通过试验观测收集了大气湍流的基本数据，并将用于分析，以得出自适应光学系统的参数，该系统补偿由于大气湍流造成的图像退化，以实现更高分辨率的观测。通过测试观测，有了新的发现，进一步证实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.
