Astronomical Imaging with Infrared Array Detectors

Science, 1988
History shows that progress in astronomy often stems directly from technological innovation and that each portion of the electromagnetic spectrum offers unique insights into the nature of the universe. Most recently, the widespread availability of infrared-sensitive two-dimensional array detectors has led to dramatic improvements in the capabilities of

DC-Squid Readout for STJ Astronomical Detectors

International Journal of Modern Physics B, 1999
The new generation of astronomical detectors based on Superconducting Tunnel Junctions (STJs) is capable of detecting photons in a wide range of wavelengths, and, in some cases, even of counting single photons. Since these detectors operate at very low temperature (down to 100 mK), a natural candidate for the readout electronics is the dc-SQUID, a ...

Astronomical polarimeter with 2-D detector arrays

Applied Optics, 1985
It is shown how fast (50–100 kHz) piezoelastic modulation of the full Stokes vector can be used in combination with large CCD-type detector arrays with long integration times. The technique is to use an optical demodulation system (replacing the lockin amplifiers in corresponding single-channel detector systems).

A lead astronomical neutrino detector: LAND

Astroparticle Physics, 1996
Abstract The development of a sensitive detector for neutrinos of astronomical origin (simply called astronomical neutrinos hereafter) would make possible detailed investigation of supernovae (SN) and open the way for the discovery of new astronomical phenomena.
