| Outline of Final Research Achievements |
Mid infrared is one of the most important wavelengths to study circumstellar disks and shells. Recent satellite telescopes have revealed that the mid-infrared radiations from those objects sometimes show strong time variation. It is very informative and interesting result, but the follow-up observations from the ground are quite difficult because of strong time variation of atmosphere in mid-infrared wavelengths.
To overcome this situation a new “2-filed simultaneous observing system” has been developed for mid-infrared observations. It is an optical device to combine two discrete fields in the telescope FoV into a single field and feed it into the astronomical camera. This device enables us to observe a science target and a reference star simultaneously, and improve the photometric accuracy dramatically.
This system can be used for 99% and 60% of known mid-infrared objects at 9 and 18 micron, respectatively.
