Long‐baseline interferometry

摘要: THE RAPID DEVELOPMENT of electronic technology has given man the ability to control electrical events in time domain with extraordinary precision, just as mechanical revolution last century improved, by orders magnitude, our power linear dimensions physical objects. Perhaps only failure analogy is quantitative; are now controllable parts 108, whereas sequences can be generated and measured 1014. The modern radio equivalent Michelson's stellar interferometer an interesting example revival old principles new forms. first motivation for building interferometers was same Michelson's: angular resolution sources electromagnetic radiation. principal difference lay limitation conventional techniques, stars visible region spectrum limited a second arc or so irregular refractin...
