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 phoLOPE 发表于 2025-3-22 08:02:16
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温和女人 发表于 2025-3-22 11:56:52

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过份好问 发表于 2025-3-23 08:34:46
