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.

10微米长基线空间干涉仪 最近，使用两台可移动的1.65米望远镜， 已完成并安装在威尔逊山。 基线已经 铺设的距离高达35米;他们可以延长在一些 方向约100米。 虽然从长远来看， 可以进行多种观测计划， 观测强调对尘埃结构的深入研究 恒星周围的壳层，它们随时间的变化， 在可见光波段被遮蔽的恒星盘的变化。 要求支持对该系统进行某些改进， 促进对可见光波长发射微弱的恒星的研究， 以提高数据的准确性和便利性， 可以采取的措施，并提供更好的设施， 分析产生的大量数据。
