Development of Mid-Infrared Astronomical imaging Technology by using High Resolution Cryogenic Fabry-Perot Interferometer

这项研究的目的是开发中红外天文成像应用中的高分辨率低温法布里-珀罗涉仪技术，以便与未来的大直径望远镜和大口径红外探测器阵列一起使用。为此，研制了一种新型超导法布里干涉仪。该装置正在与亚利桑那大学中红外天文小组合作进行测试。还对配备法布里-珀罗涉仪的红外相机的光学进行了研究。对非球面同轴三镜系统和离轴两镜锥面系统等光学设计进行了研究和优化。后一种配置的系统在斯图尔德天文台60英寸望远镜上成功地进行了测试。提出了一种新的“双波长移位相加”技术，该技术特别适用于微弱的中红外扩展天文目标的成像，并在样机上进行了测试，表明该系统的探测能力有了很大的提高。

This research is aimed at developing technology for high resolution cryogenic Fabry-Perot interferometers in mid-infrared astronomical imaging applications to be used in conjunction with the future large diameter telescopes and large format infrared detector arrays. A new cryogenic Fabry-Interferometer with superconducting actuators is developed for this purpose. This unit is being tested in collaboration with the mid-infrared astronomy group at the University of Arizona.Optics for infrared camera equipped with the Fabry-Perot interferometer is also inbestigated. Optical designs such as non-spherical coaxial three mirror system or off-axis two mirror conic surface system are studied and optimized. A system with the latter configuration is tested on the Steward Observatory 60 inch telescope succesfully. A new "Two-Wavelength Shift-And-Add" technique which is especially suited for the imaging of faint mid-infrared extended astronomical objects are developed and tested in a prototype camera to show a dramatical improvement in the detectibity of the system.
