Ukufunyanwa kwesiginali yokukhanyai-spectrometer yehardware
A i-spectrometersisixhobo sokubona esahlula ukukhanya kwe-polychromatic kwi-spectrum. Kukho iintlobo ezininzi zee-spectrometer, ukongeza kwii-spectrometer ezisetyenziswa kwi-visceral light band, kukho ii-infrared spectrometers kunye nee-ultraviolet spectrometers. Ngokwezinto ezahlukeneyo ze-dispersion, inokwahlulwa ibe yi-prism spectrometer, i-grating spectrometer kunye ne-interference spectrometer. Ngokwendlela yokufumanisa, kukho ii-spectroscopes zokujonga ngqo amehlo, ii-spectroscopes zokurekhoda ngeefilimu ezibonisa ukukhanya, kunye nee-spectrophotometers zokubona ii-spectra ezine-photoelectric okanye ii-thermoelectric elements. I-monochromator sisixhobo se-spectral esikhupha umgca omnye we-chromatographic kwi-slit, kwaye sisetyenziswa rhoqo kunye nezinye izixhobo zohlalutyo.
I-spectrometer eqhelekileyo ineqonga le-optical kunye nenkqubo yokufumanisa. Iquka ezi ndawo zilandelayo ziphambili:
1. Uqhekeko lwesiganeko: indawo yento yenkqubo yokufota ye-spectrometer eyenziwe phantsi kokukhanya kwesibane sesiganeko.
2. I-Collimation element: ukukhanya okukhutshwa yi-slit kuba kukukhanya okulinganayo. I-collimating element inokuba yilensi ezimeleyo, isibuko, okanye idityaniswe ngokuthe ngqo kwi-dispersing element, njenge-concave grating kwi-concave grating spectrometer.
(3) Into yokusasazeka: kusetyenziswa i-grating, ukuze isignali yokukhanya esithubeni ngokwe-wavelength dispersion ibe yimisebe emininzi.
4. Isici sokugxila: Gxila kwi-dispersive beam ukuze yenze uthotho lwemifanekiso ye-incident slit kwi-focal plane, apho indawo nganye yomfanekiso ihambelana nobude be-wavelength ethile.
5. Uluhlu lwe-detector: lubekwe kwindawo egxile ekulinganiseni ukukhanya kwenqaku ngalinye lomfanekiso we-wavelength. Uluhlu lwe-detector lunokuba luluhlu lwe-CCD okanye olunye uhlobo loluhlu lwe-detector lokukhanya.
Iispectrometers ezixhaphakileyo kwiilabhoratri ezinkulu zii-CT structures, kwaye olu didi lweespectrometers lukwabizwa ngokuba zii-monochromators, ezahlulwe zibe ziindidi ezimbini:
1, isakhiwo se-CT esijikelezayo esingaphandle kwe-axis, esi sakhiwo yindlela yangaphakathi ye-optical ehambelana ngokupheleleyo, ivili le-grating tower line-axis enye ephakathi kuphela. Ngenxa yokulingana okupheleleyo, kuya kubakho ukwahlukana kwesibini, okubangela ukukhanya okunamandla kakhulu, kwaye ngenxa yokuba kukukhangela okungaphandle kwe-axis, ukuchaneka kuya kuncipha.
2, isakhiwo se-CT sokuskena i-axial esingalinganiyo, oko kukuthi, indlela yangaphakathi ye-optical ayilinganiyo ngokupheleleyo, ivili le-grating tower line-axes ezimbini eziphakathi, ukuqinisekisa ukuba ukujikeleza kwe-grating kuskenwa kwi-axis, kuthintele ngokufanelekileyo ukukhanya okulahlekileyo, kuphucule ukuchaneka. Uyilo lwesakhiwo se-CT sokuskena i-axial esingalinganiyo lujikeleza kumanqaku amathathu aphambili: ukwenza ngcono umgangatho womfanekiso, ukususa ukukhanya kwesibini okudityanisiweyo, kunye nokwandisa ukukhanya okukhanyayo.
Izinto eziphambili zayo zezi: A. incidentumthombo wokukhanyaB. Isithuba sokungena C. isibuko esidibanisayo D. igrating E. isibuko esigxileyo F. Isithuba sokuphuma (isithuba) G.isixhobo sokubona iifoto
I-Spectroscope (i-Spectroscope) sisixhobo sesayensi esihlulahlula ukukhanya okuntsonkothileyo kube yimigca ye-spectral, equka iiprism okanye ii-diffraction gratings, njl.njl., kusetyenziswa i-spectrometer ukulinganisa ukukhanya okubonakaliswa kumphezulu wento. Ukukhanya okunemibala esixhenxe elangeni yinxalenye yeliso elingenanto inokwahlulwa (ukukhanya okubonakalayo), kodwa ukuba i-spectrometer iya kubola ilanga, ngokwelungiselelo le-wavelength, ukukhanya okubonakalayo kubala kuphela uluhlu oluncinci lwe-spectrum, okuseleyo kukuba iliso elingenanto alikwazi ukwahlula i-spectrum, njenge-infrared, i-microwave, i-ultraviolet, i-X-ray njalo njalo. Ngokuthatha ulwazi lokukhanya yi-spectrometer, uphuhliso lweepleyiti zefoto, okanye ukubonisa ngokuzenzekelayo kwezixhobo zamanani ngekhompyutha, ukuze kufunyanwe ukuba zeziphi izinto eziqulethwe kwinqaku. Le teknoloji isetyenziswa kakhulu ekufumaneni ungcoliseko lomoya, ungcoliseko lwamanzi, ucoceko lokutya, ishishini lesinyithi njalo njalo.
