The Determination of Absolute Phase of a Long Baseline Interferometer and its Application to the Precise Measurement of the Constant of Nutation

摘要: Long Baseline Interferometry (L.B.I.) refers to a dramatic technical breakthrough in astronomy accomplished almost exactly ten years ago the spring of 1967 by group workers at National Research Council Canada and some major Canadian Universities. The effort was duplicated within month an independent American it realized soon afterward that new technique L.B.I, held enormous potential for geodynamical as well astronomical studies.
