Far Infrared Interferometric Telescope
The Far Infrared Interferometric Telescope (FITE) is an interferometric reflector telescope for astronomical observations in the far infrared spectral range . In order to overcome the absorption of the atmosphere in this spectral range , the telescope is carried by a balloon at a height of over 30 km. To increase the resolution , it consists of two mirrors 20 m away with an aperture of 412 mm each, the light of which is combined interferometrically . This enables angular resolutions of up to one arc second at 100 µm wavelength.
The project is a collaboration of the University of Nagoya , the Osaka University , both of Japan, and the Japan Aerospace Exploration Agency . The start originally planned for 2008 in Brazil has been postponed several times and should take place in 2018.
