Abstract

Infrared astronomy is considerably affected by the continuing advances in detectors, electronics and computing for control and instrumentation; it also makes important contributions in these areas. Ground-based astronomy at one to thirty-five microns is now background shot-noise limited for broadband photometry in most atmospheric windows. Present techniques under development emphasize higher spatial and spectral resolution, and on-line presentation of results. Telescope design has evolved to ensure lower instrumental contribution to the background radiation, and both imaging and positional control have improved to allow efficient utilization of the new instrumentation. In a non-specialist qualitative approach, some of the more interesting developments are briefly discussed.
