EARLY INFRARED ASTRONOMY

Journal of Astronomical History and Heritage, 2009
I present a short history of infrared astronomy, from the first scientific approaches of the `radiant heat' in the seventeenth century to the 1970's, the time when space infrared astronomy was developing very rapidly. The beginning of millimeter and submillimeter astronomy is also covered. As the progress of infrared astronomy was strongly dependent on

Detectors for Infrared Astronomy

Optical Engineering, 1977
Many of the recent advances in infrared astronomy have been the result of improved performance of existing infrared detectors or the introduction of new detectors. This paper includes a brief examination of the background photon fluxes encountered in infrared astronomy and the effect on detector performance of the fluctuation in this background.

Infrared Astronomy

, 1994
What do we understand of the birth and death of stars? What is the nature of the tiny dust grains that permeate our Galaxy and other galaxies? And how likely is the existence of brown dwarfs, extrasolar planets or other sub-stellar mass objects? These are just a few of the questions that can now be addressed in a new era of infrared observations.

Handbook of Infrared Astronomy

, 1999
Infrared astronomy has been revolutionised in the last few years by the advent of large, sensitive, infrared arrays, and the success of several infrared satellites. This handbook provides a clear, concise and accessible reference on all aspects of infrared astronomy.
