Since a bolometer measures power, or photon number, it is not bound to add quantum noise stemming from the Heisenberg uncertainty principle in the way that parametric amplifiers are.

Radiation-detectors known as bolometers are vital instruments in many fields of science.

Normally, the South Pole Telescope’s 10-meter dish funnels extremely faint radiation from the cosmic microwave background into a camera called a bolometer.

Herschel used special light detectors in its instruments known as bolometers.

Observations taken with a bolometer along the length of a normal or wave-length spectrum, would give the form of the curve plotted on a wave-length base.
