Bolometer

A bolometer (Greek: βολόμετρον "bolometron", meaning measurer (-μετρον) of thrown things (βολο-)) is a device for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature-dependent electrical resistance.

Cassegrain reflector

The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas.

Cosmic microwave background

The cosmic microwave background (CMB) is the thermal radiation left over from the time of recombination in Big Bang cosmology.

Degree Angular Scale Interferometer

The Degree Angular Scale Interferometer (DASI) was a telescope installed at the U.S. National Science Foundation's Amundsen–Scott South Pole Station in Antarctica.

Interferometry

Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves.

List of cosmic microwave background experiments

This list is a compilation of experiments measuring the cosmic microwave background (CMB) radiation anisotropies and polarization since the first detection of the CMB by Penzias and Wilson in 1964.

Polarization (waves)

Polarization (also polarisation) is a property of waves that can oscillate with more than one orientation.

South Pole

The South Pole, also known as the Geographic South Pole, Celestial South Pole, or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface (also see Celestial pole).
