Refinements of a Mid-Infrared Spatial Interferometer and Data Processing for General Astronomical Observations

使用两个可移动的1.65米望远镜的10微米波长区域的长基线空间干涉仪最近已经完成，并安装在威尔逊山上。目前已经制定了长达35米的基线；它们在某些方向上可以延伸到大约100米。虽然从长远来看，可以进行广泛而多样的观测计划，但目前的观测重点是深入研究恒星周围尘埃壳的结构，它们随时间的变化，以及在可见波长下被遮挡的恒星圆盘的大小和变化。要求对该系统进行一些改进，以便利对可见光波长发射较弱的恒星开展工作，提高获取能见度数据的精确度和便利性，并提供更好的设施来分析产生的大量数据。

A long-baseline spatial interferometer for the 10 microns wavelength region using two movable 1.65 m telescopes has recently been completed and installed on Mount Wilson. Baselines have been laid out for distances up to 35 m; they can be extended in some directions to about 100 m. Although in the long run an extensive and varied observational program can be carried out, present observations emphasize an intensive study of the structure of dust shells around stars, their change with time, and the sizes and changes in the disks of stars obscured at visable wavelengths. Support is requested for some improvements to the system to facilitate work on stars with weak emission at visible wavelengths, to enhance the precision and facility with which data on visibilities can be taken, and to provide better facilities to analyze the substantial amount of data which is produced.
