Infrared array detectors, like silicon CCDs a decade before, have revolutionized infrared astronomy. The quality and performance of the current generation of devices has already allowed astronomers to obtain infrared images at wavelengths out to 2.2 microns which are as deep as the best CCD images. High resolution infrared spectroscopy is now a reality and ground-based imaging to 35 microns has been achieved. Several classes of low-noise infrared array detectors with formats of 256 × 256 pixels are now in routine use, and developments are under way which will produce detectors of 1024 × 1024 pixels (for the near IR) within the next year. This paper will briefly review the state-of-the-art and compare and contrast the properties of available arrays. Progress in the field is illustrated with recent near infrared photometry obtained with a new two-channel imaging system developed at UCLA.
