论文摘要
干涉法是一种使天空敏感,高保真图像的强大技术,但其测量扩展或扩散发射的能力受到限制。可以通过将干涉仪阵列的许多指标摩塞到延长天文对象的更好的图像。可以通过将这些数据与单次望远镜的数据相结合来获得更好的图像。该讲座解释了通常实践的技术,用于获取和分析这些观察以及它们背后的理论。
Interferometry is a powerful technique for making sensitive, high-fidelity images of the sky, but is limited in its ability to measure extended or diffuse emission. Better images of extended astronomical objects can be obtained by mosaicking together many pointings of the interferometer array. Even better images can be obtained by combining these data with data from a single-dish telescope. This lecture explains commonly practiced techniques for obtaining and analyzing these observations, and the theory behind them.
