描述A revolution similar to that brought by CCDs to visibleastronomy is still ahead in IR and submillimeter astronomy. There iscertainly no wavelength range which has, over the past several years,seen such impressive advances in technology: large-scale detectorarrays, new designs for cooling in space, lightweight mirrortechnologies. Scientific cases for observing the cold universe areoutstanding. Observations in the FIR/Submm range will provide answersto such fundamental questions as: What is the spectrum of theprimordial fluctuations? How do primeval galaxies look? What are thefirst stages of star formation? Most of the international spacemissions that have been triggered by these questions are presented indetail here. Technological issues raised by these missions arereviewed, as are the most recent achievements in cooling and detectortechnologies. .

Detection Limits in the Far Infrared,ditional “confusion limits” will be extracted from images by using computer algorithms similar to CLEAN or DAOPHOT. We have conducted numerical experiments to evaluate these techniques and show that they will permit long integrations (~ 10,000 sec at 60 .m, ~ 200 sec at 100 .m) to achieve nearly pho

Background Limited Infrared and Submillimeter Instruments, space projects. They determine also, among other parameters, the self-emission of the instrument and the photon noise produced by this radiation on the detectors. By comparing the telescope brightness with that of the sky in the 1µm-1 cm wavelength range, general conditions for background limited p

Infrared Telescope in Space: IRTS,iments aboard the small space platform, SFU. The telescope aperture of the IRTS is 15cm, but is cooled by liquid Helium to realize very low background condition. Four instruments are installed on the focal plane which cover wide wavelengths from near infrared to submillimeter regions. The IRTS is op
