长基线光干涉与天体测量

Long Baseline Optical Interferometry and Astrometry

过去的十年中,长基线恒星光干涉测量技术在国际上已得到相当的发展,它和所有的新技术一样,对天文学的发展将起到举足轻重的作用。本文介绍了恒星光干涉测量在基本天体测量学方面的科学意义、应用前景、仪器的基本结构、美国的MARKⅢ天体测量干涉仪所取得的初步观测结果,并且展望了90年代在天体测量学发展中应用光学干涉仪的广阔前景。

During the last decade, the long baseline optical interferometry was considerably developed and a number of measurements with high resolutions on astrometry and astrophysics were obtained. It is very similar to all kinds of new techniques that stellar interferometry would be a highly contributing means in the development of astronomy. This paper describes, at the point of view of astrometry, the scientific significance of optical interferometry, its applications, the basic structure of instruments, the preliminary results of MARK Ⅲ interferometer of U. S., and the prospect of optical interferometry in the development of astrometry in next decade 1990s.
