| Zusammenfassung |
| The novel airborne Gimballed Limb Observer for Radiance Imaging of
the Atmosphere (GLORIA) measures infrared emission of atmospheric
trace constituents. GLORIA comprises a cooled imaging Fourier
transform spectrometer, which is operated in unpressurized aircraft
compartments at ambient temperature. The whole spectrometer is
pointed by the gimbal towards the atmospheric target. In order to
reach the required sensitivity for atmospheric emission measurements,
the spectrometer optics needs to operate at a temperature below
220 K. A lightweight and compact design is mandatory due to
limited space and high agility requirements. The cooled optical
system needs to withstand high pressure and temperature gradients,
humidity, and vibrations. A new cooling system based on carbon
dioxide and liquid nitrogen combined with high-performance
insulation has been developed to meet the mechanical, thermal, and
logistical demands. The challenging mechanical and spatial
requirements lead to the development of a novel rigid linear slide
design in order to achieve the large optical path difference for
high spectral resolution. This paper describes the mechanical and
thermal setup of GLORIA and presents the performance results on two
different research aircrafts. |
