摘要: New theoretical results for noise in cryogenic bolometers are derived. Johnson is reduced by as much 60% electrothermal feedback from the bias supply. Phonon thermal link 30% relative to usual equilibrium formula. Photon Rayleigh-Jeans limit computed with attention attenuation of photon correlations light beam. Basic on bolometer responsivity, time constant, and properties presented a new convenient form. Excess 1/f contact shot also discussed.
