Detector technology
Bolometer
A detector that measures light by the tiny rise in temperature it causes in an absorbing element — the standard way to detect the faint millimetre and submillimetre sky, including the cosmic microwave background. Cooled to a fraction of a degree above absolute zero; the South Pole Telescope's cameras use large bolometer arrays.
