The temperature is determined by measuring the infrared radiation from the object.

Hot components continuously radiate heat to their environment in the form of infrared radiation.

Human beings, while not as hot as a spacecraft tailpipe, also emit infrared radiation.

Electromagnetic waves with this vibration frequency are called infrared radiation.

That had been the source of the infrared radiation.

But astronomers have not detected any infrared radiation, suggesting there is no disk at all.

They can detect fire chemicals at very low concentrations, as well as infrared radiation from fires.

It also does not emit any infrared radiation.

Because their atoms are constantly in motion, they give off some degree of heat or infrared radiation.

Radiant methods of heat transfer impart energy in the form of electromagnetic energy, typically microwaves or infrared radiation.

But the grains quickly re-emit the light, as infrared radiation or at wavelengths more similar to radio waves.

However, there are other contributing factors, for example, atmospheric factors such as air pollution, visible light and infrared radiation.

Judging from the lack of change in the cardiac action potential duration, heart cells do not preferentially absorb infrared radiation.

Aims: The corneal temperature change following each blink was investigated in patients with dry eye using an infrared radiation thermometer.

Blackbody infrared radiation was applied to pump an ion population into a well-defined internal energy distribution below the dissociation threshold.

Its sensor's amorphous silicon pixels respond to infrared radiation, showing differences in surface temperature down to half a degree centigrade.
