TL;DR: The Spectral and Photometric Imaging REceiver (SPIRE) is the Herschel Space Observatory's sub-millimetre camera and spectrometer as discussed by the authors, which is used for image and spectroscopic data acquisition.

TL;DR: The Spectral and Photometric Imaging Receiver (SPIRE) as discussed by the authors is the Herschel Space Observatory's submillimetre camera and spectrometer, which is used for scan-mapping, whereby the field of view is scanned across the sky to achieve full spatial sampling and to cover large areas.

TL;DR: SPIDER as mentioned in this paper is a balloon-borne experiment designed to measure the polarization of the Cosmic Microwave Background (CMB) on large angular scales, and the primary goal of SPIDER is to detect the faint signature of inflationary gravitational waves in the CMB polarization.

TL;DR: The High Frequency Instrument (HFI) on the NASA/ESA Planck Surveyor is scheduled for launch in 2007 and will map the entire sky in 6 frequency bands ranging from 100 GHz to 857 GHz to probe Cosmic Microwave Background (CMB) anisotropy and polarization with angular resolution ranging from 9' to 5'.

TL;DR: The high frequency instrument (HFI) on the National Aeronautics and Space Administration/European Space Agency Planck Surveyor, scheduled for launch in 2007, will map the entire sky in six frequency bands ranging from 100 to 857 GHz to probe cosmic microwave background anisotropy and polarization with angular resolution ranging from 9[prime] to 5[prime]. The HFI focal plane will contain 48 silicon-nitride micromesh bolometers operating from a 100 mK heat sink as discussed by the authors.
