A scanning Fabry-Perot interferometer for far-infrared balloon astronomy

Infrared Physics, 1978
Abstract Design and performance details of a scanning Fabry-Perot interferometer developed for far-infrared balloon astronomy are presented. Scanning is achieved mechanically by a parallel spring arrangement and plate spacing is measured by capacitance micrometry.

Lumped element kinetic inductance detectors for far-infrared astronomy

SPIE Proceedings, 2008
We describe a new type of FIR detector based on lumped element superconducting resonators (LEKIDs). Thesedevices can act as distributed FIR radiation absorbers without the need for an additional coupling structure.In addition, these devices can be integrated into a compact filled array geometry with high filling factor.

Atmospheric windows and broad band photometry in far infrared astronomy

Infrared Physics, 1974
Abstract The far infrared atmospheric windows between 30 cm −1 and 5 cm −1 have been investigated during many months of observations at the Alpine Station of Testa Grigia (3500 m a.s.l.). The seasonal and diurnal variation of the atmospheric transmittance for each window have been measured.

Mid- and far-infrared hybrid focal plane arrays for astronomy

SPIE Proceedings, 1998
ABSTRACTHigh performance 128x128 Si:As and Si:Sb Blocked-Impurity-Band (BIB) hybrid arrays have been developed for ground-based and airborne astronomy. These devices cover the 5-25 (Si:As) and 15-40 jtm(Si:Sb) portions of the spectrum. The peak detective quantum efficiencies exceed 50% for Si:As and 30%for Si:Sb.

Bandpass interference filters for very far infrared astronomy

Infrared Physics, 1980
Abstract Three bandpass filters have been constructed for use with a 0.3K bolometer. The center frequencies and bandwidths of the filters are chosen to correspond with the 1, 2 and 3 mm atmospheric windows. The filters are formed of resonant metallic grids separated by air spacers.

A 102-cm Balloon-Borne Telescope for Far-Infrared Astronomy

Optical Engineering, 1977
The Center for Astrophysics-University of Arizona balloon-borne, inertially-guided, 102 cm telescope was designed to perform photometry and high resolution mapping of far-infrared (40-250 micron) celestial sources. To date the telescope has now been flown and successfully recovered a total of ten times.

SPICA: a new space telescope for mid- and far-infrared astronomy

Advances in Space Research, 2002
Abstract We present the concept of the SPICA (Space Infrared Telescope for Cosmology and Astrophysics, previously known as HII/L2) mission, which incorporates a 3.5 m telescope cooled to 4.5 K. SPICA will focus on high-resolution mid- to far-infrared observations with unprecedented sensitivity. It will make great contributions to our understanding of
