项目摘要

We carried out observations of four external galaxies and, depths of our Galactic plane with TRISPEC on UH88 and UKIRT telescopes atop Mauna Kea.We summarize the activities for these three years ;In 1999, test observations in April at Mitaka, shipping to Mauna Kea in May, imaging observation at UH88 for 4 nights in June, install the spectroscopic mode in August, spectroscopic observation at UH88 for 3 nights in September, install the polarimetric mode in December, and polarimetric observation in January at UKIRT.In 2000, in August, Januray and March, three times in total, polarimetric observations at UKIRT.In 2001, returned TRISPEC to Nagoya in May and searched the origin of the flaws of mismatch of "pupils" between optical and infrared bands. We found the mis-alignment of optical axis by 2 mm from the mechanical center for the LiF lens.We published one refereed paper and two Ph.D. thesis by Hidehiko Nakaya and Makoto Watanabe, and two Master thesis by Atsushi Yamazaki and Yusuke Yamanaka from the TRISPEC project for these three years. I believe that it was important for learning various styles of developments both for human resources and basic instruments, and we have contiributed to manufacturing the crystal lenses.

我们用UH88望远镜上的TRISPEC和莫纳克亚山顶的UKIRT望远镜对四个外星系和银道面深度进行了观测。1999年，4月在Mitaka进行了试验观测，5月运往Mauna Kea，6月在UH88进行了4个晚上的成像观测，8月安装了分光模式，2000年9月在UH88进行了3个晚上的光谱观测，12月安装偏振模式，1月在UKIRT进行偏振观测。2000年8月、1月和3月在UKIRT进行了3次偏振观测。2001年，TRISPEC于5月返回名古屋，并对光学和红外波段之间“瞳孔”不匹配的缺陷进行了调查。我们发现LiF透镜的光轴偏离机械中心2 mm。这三年来，TRISPEC项目中的两篇论文分别是Hidehiko Nakaya和Makoto Watanabe的论文，以及Atsushi Yamazaki和Yusuke Yamanaka的两篇硕士论文。我相信学习人力资源和基础仪器的各种类型的发展非常重要，我们一直致力于制造水晶透镜。
