Astronomical Imaging with Infrared Array Detectors
Science, 1988History 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, 1999The 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, 1985It 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, 1996Abstract 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.

EUV Astronomical Spectroscopy With CCD Detectors
SPIE Proceedings, 1986The applicability of CCD detectors to astronomical extreme ultraviolet (EUV) spectroscopy (100-1250 A) is discussed. The advantages of CCDs in this spectral region include internal electron yield, the potential for very high quantum efficiency (about 50-90 percent), and broad wavelength response.

Astronomical detectors for .001 to 300000 AA, an overview
Journal of Optics, 1987A variety of imaging devices are necessary in astronomy, not only to cover the observable electromagnetic spectrum but also because of constraints on time resolution and signal-to-noise. Representative imagers are listed and a few specific applications discussed.

Advances in detectors for astronomical spectroscopy
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1982Abstract Image-reproducing detectors for ultraviolet, optical and near infrared spectroscopic applications in astronomy are described. Emphasis is placed on detectors of the image photon-counting type and on charge-coupled devices.

The charge-coupled device (CCD) is the foremost imaging device in observational astronomy. The CCD has high quantum efficiency and linearity compared to film, but it suffers from several sources of noise. We illustrate how to reduce noise by backing and applying flat, bias, and dark frames.
