Lub SI chav nyob ntawm qhov tawm ntawm qhov hluav taws xob yog qhov watt ib square meter (W/m 2) , thaum lub spectral tawm hauv zaus yog watt ib square meter ib hertz (W·m−2·Hz− 1) thiab cov spectral tawm hauv wavelength yog watt ib square meter ib 'meter' (W·m−3 )-feem ntau cov watt ib square meter ib nanometer (W·m−2·nm− 1).
Yuav ua li cas yog tus qauv ntawm radiant flux?
W=J/s . M⋅L2⋅T-3. Radiant zog emissions, reflected, kis los yog tau txais, ib chav tsev lub sij hawm. Qhov no qee zaum kuj hu ua "radiant power". Spectral flux.
Koj suav li cas radiant flux ceev?
Qhov ntom rau qhov tshwm sim flux ntawm qhov chaw hu ua Irradiance. Qhov ntom rau flux tawm ntawm qhov chaw hu ua Emittance lossis Exitance. 500 deg K Page 6 CE 603 Photogrammetry II Hloov cov units ntawm S(λ) los ntawm kev sib npaug ntawm 1E-06, hloov mus rau spectral exitance, M(λ) los ntawm kev sib npaug ntawm pi.
Dab tsi yog qhov tawm ntawm lub teeb ci laser?
Radiant tawm (los yog emittance) yog ib lub sij hawm ntawm radiometry thiab yog txhais raws li lub radiant flux (optical zog=lub zog ib lub sij hawm) uas yog emissions los ntawm tej nto (xws li. ntawm lub teeb ci) ib cheeb tsam.
Kev siv zog ntawm lub zog hluav taws xob yog dab tsi?
Nyob hauv radiometry, radiant siv yog theradiant flux emitted, reflected, kis los yog tau txais, ib unit khoom lub kaum sab xis, thiab spectral siv yog lub radiant siv ib unit zaus los yog wavelength, nyob ntawm seb lub spectrum yog npaum li cas los ntawm ntau zaus los yog wavelength.
