bolometers

Aimed at the stretch of sky between the Earth below and the balloon above, the device was able to measure temperature differences in the cosmic microwave background of less than one hundred-millionth of a degree Celsius, using devices called bolometers.

Its telescopes, especially designed with the aims of the physicist and chemist in view, bring images of sun, stars, nebulæ, and other heavenly bodies within the reach of powerful spectroscopes, sensitive bolometers and thermopiles, and the long array of other appliances available for the measurement and analysis of radiation.

Dr. Lange, working with James Bock, now at NASA's Jet Propulsion Laboratory, built new detectors, known as spider web bolometers, designed for studying the cosmic microwave work.

"More and more things are coming together," says Werner, noting the group now has field-installed test set-ups for pressure sensors, silicon microphones, inertial sensors, micro mirrors and micro bolometers.

The bolometers are sensitive enough to detect the different energies of the photons, and thus can measure the fine-scale temperature variation in the microwave background.
