Infrared Telescopes:Balloon-Borne

Scientific paper

A balloon-borne 75 cm aperture Cassegrain telescope has been developed for far-infrared astronomical observations. This telescope uses a three axis stabilised platform which is designed to orient the optic axis with an accuracy of ≈0.5 min of arc. A star sensor is used for the guidance. The secondary mirror is chopped at 20 Hz and the signals from the infrared detector are analysed by a phase sensitive detector (PSD). The gain of the PSD can be changed during the flight to provide an overall dynamic range of 1.5×105. The telescope was flown at an altitude of 32 km for photometric observations in 80 μm to 120 μm wavelength band. An aperture of 4 min of arc was used and a sensitivity of 100 Jy was expected.
