Cov hluav taws xob hluav taws xob infrared, tseem hu ua infrared thermal hluav taws xob, muaj lub zog thermal nyhuv. Tshuaj saum toj kawg nkaus xoom (0 k, uas yog,: 273,.
Lub teeb lub teeb pom kev zoo yog nyob sab nraum lub tsom iav pom ntawm lub nra tawm, nrog wavelengths xws li 0.8μm rau 50μm, uas ntev dua li pom spectrum (0.4μm rau 0.8μm).

Yog li dab tsi yog qhov kev sib raug zoo ntawm wavelength thiab zaus?

λ = C / F, qhov twg C yog qhov ceev ntawm lub teeb 3.0 × 108 m / s thiab λ yog nthwv cua.
Piv txwv li: Qhov zaus ntawm pom lub teeb yog kwv yees li ntawm 4x1014Hz ~ 8x1014Hz.


2. Infrared hluav taws xob - Cov Recospheric Window
Cov roj av ntau ntxiv uas ua rau lub ntiaj teb cov cua nqus tau feem ntau ntawm cov hluav taws xob hluav taws xob hluav taws xob, tawm tsuas yog qee qhov scriation infiation.
Ntawm lawv, ib feem nrog kev hloov pauv siab dua yog hu ua "hluav taws xob hluav taws xob hluav taws xob hluav taws xob".
Nyob rau hauv luv luv - yoj, nruab nrab - yoj thiab ntev - yoj spectral lub qhov rais yog 0.7 ~ 5μm thiab 8 ~ 14μm feem;
