I participated in high energy laser development and in infrared measurements of terrestrial backgrounds from aircraft.

From infrared measurements, they infer that the planet is still very hot, about 3,000 degrees Fahrenheit, with water and carbon monoxide in its atmosphere.

Finely-deposited gold is used for infrared measurements.

The infrared measurements should tell whether it is a layer of cold or haze in the lower atmosphere.

When conducting infrared measurements, it is necessary to keep the infrared detectors cooled to avoid having infrared interference from the instrument's own thermal emissions.

But infrared measurements of heat radiating from the object led researchers to estimate its diameter at no more than 1,100 miles.

Rotational constants obtained from infrared measurements are in good accord with those obtained by microwave spectroscopy while the latter usually offers greater precision.

Through infrared and ultraviolet measurements, trace amounts of benzene and other hydrocarbons have also been found.

Photometric calibrations and infrared spectroscopic measurements indicate that the star is enriched in heavy elements compared to the Sun.

Modern research instruments can take infrared measurements across the range of interest as frequently as 32 times a second.
