Basic Study on the System of Optical Camera Arrays with Wide Field of View for Transient Astronomical Objects

本研究的主要目的是研制大视场光学望远镜阵列的基本系统。该望远镜阵列可以在地面上对大视场天空进行连续监测。因此，该系统可以检测瞬态对象的外观是不可预测的一般。为了实现这一系统，我们必须研制三个项目：（1）研制大视场的光学望远镜，（2）研制大探测面积的CCD作为焦平面探测器，（3）研制海量成像数据处理软件。这一有限的赠款是为了开发一个具有宽视场的光学望远镜，而我们只使用了传统的CCD和软件。我们已经开发了一个折射光学望远镜与5度和直径20厘米的领域。如此大视场的望远镜迄今还没有实现过。我们首先在实验室对该望远镜进行了基本测试，然后在八岳山进行了野外测试。我们观察到 ...更多信息 一个疏散星团，M45（或“斯巴鲁”）。我们在10秒的曝光时间内以0.1等的精度探测到了一颗12等的星星。噪声级对应于60e，但现在已改进为30e。该系统不需要机械运动系统就可以拍摄任何天空图像，而用CCD电子学系统可以跟踪焦平面上的天空图像，在5 °范围内图像清晰，精度可达几角秒。在CCD驱动系统中，我们开发了TDI驱动系统。这样，我们就可以在野外不移动望远镜系统的情况下拍摄到清晰的图像。目前的光学望远镜有一个新的系统。因此，我们提出了一项通用专利。虽然我们已经实现了主要的发展目标，但还需要进一步研究另外两个项目，即（1）大视场CCD和（2）大规模成像数据处理软件。少

The main object of this research is to develop a basic system of the optical telescope array with wide field of view. This telescope array can monitor wide field of sky on the ground continuously. Therefore, this system can detect the transient objects whose appearance are not predictable in general. We have to develop three items in order to realize this system as follows ; that is, (1) to develop an optical telescope with wide field of view, (2) to develop a CCD with large detection area as a forcal plane detector and (3) to develop the software for processing mass imaging data. This limited grant is to develop an optical telescope with wide field of view, while we used only conventional CCD and software.We have develop the refractive optical telescope with a field of 5 degrees and 20 cm in diameter. Such wide field of telescope has not been realized so far. We have done basic tests of this telescope firstly in the laboratory and secondary in the fields on Mt.Yatsugatake. We observed … More an open cluster, M45 (or "Subaru"). We detected a 12 magnitude star with a precision of 0.1 magnitude in 10 second exposure time. The noise level corresponded to 60e, but now it has been improved to be 30e. Any sky image can be taken without mechanical moving system, but the sky image on the focal plane can be followed with electronics system of CCD.The image within 5 degrees are lake clearly with a precision of a few arc seconds. We have developed a driving system with TDI in the CCD driving system. Thus we could take a clear image in the fields without moving system for the telescope. The present optical telescope has a new system. Therefore we have proposed a patent for general usage. if we make a telescope array consisting of 100 telescopes or more in future, we can monitor the sky of one steradian.Although we have achieved the main object to be developed, we have to develop other two items for futute study ; that is, (1) CCD with a wide field of view and (2) software for processing mass imaging data.
