Ukutholwa kwesiginali ye-Optical SignalI-Hardware Spectrometer
A spectrometeriyithuluzi elibonakalayo elihlukanisa ukukhanya kwe-polychromatic ku-spectrum. Kunezinhlobo eziningi zama-spectrometer, ngaphezu kwama-spectrometers asetshenziswa embonini ebonakalayo yokukhanya, kukhona ama-spectrometers we-infrared kanye nama-ultraviolet spectrometers. Ngokwezinto ezahlukahlukene zokuhlakazeka, zingahlukaniswa nge-prism Spectrometer, i-spectrometer ye-grating kanye ne-infference spectrometer. Ngokwendlela yokutholwa, kukhona ama-spectroscopes wokubhekwa kwamehlo okuqondile, ama-spectroscopes okurekhoda ngamafilimu ezithombe, nama-spectrophotometers ukuthola izinto ezibonakalayo nge-PhotoElectric noma izinto ze-thermoelectric. I-monochromator iyithuluzi elibukhali eliphuma kulayini owodwa we-chromatographic ngokusebenzisa isilonda, futhi kuvame ukusetshenziswa ngokubambisana nezinye izinsimbi zokuhlaziya.
I-spectrometer ejwayelekile iqukethe ipulatifomu ye-optical kanye nohlelo lokutholwa. Kubandakanya izingxenye eziphambili ezilandelayo:
1. Isigameko Slit: Iphuzu lento yohlelo lokucabanga lwe-spectrometer eyakhiwa ngaphansi kokufakelwa ukukhanya kwesigameko.
2. Into yokulinganisa: Ukukhanya okukhishwe yi-slit kuba ukukhanya okufanayo. Into epholile kungenzeka ibe yilensi ezimele, isibuko, noma ehlanganiswe ngokuqondile kwinto ehlakazayo, njenge-concave grating ku-concave grating spectrometer.
.
I-4. Ukugxila kwento: gxila ugongolo oluhlakazekile ukuze kwakha uchungechunge lwezinto ezenzakalweni zezindiza endizeni egxile kuyo, lapho isithombe ngasinye sesithombe sihambelana khona ne-wavelength ethile.
5 I-detector array ingaba yi-array ye-CCD noma ezinye izinhlobo zokuhlelela umtshina wokukhanya.
Ama-spectrometer ajwayelekile ezindaweni eziphakeme zama-latoratories yizakhiwo ze-CT, futhi leli klasi lama-spectrometer libizwa nangokuthi ama-monochromators, ahlukaniswe izigaba ezimbili:
I-1, symmetrical off-axis scan scan esakhiwo, lesi sakhiwo yindlela yangaphakathi ye-optical ifana ngokuphelele, isondo le-grating tower line-axis eyodwa ephakathi. Ngenxa yokuvumelanisa okuphelele, kuzoba nokuphazamiseka kwesibili, okuholela ekukhanyeni okuqinile okuqinile, futhi ngoba kungukuskena kwe-aff-axis, ukunemba kuzoncishiswa.
2, i-asymmetric axial scanning yesakhiwo se-CT, okungukuthi, indlela yangaphakathi ye-optical ayikho ngokuphelele, i-graing tower isondo linezimbambo ezimbili eziphakathi nendawo, ukuqinisekisa ukuthi ukujikeleza kwe-grating kuskenwa e-eksisi, kuvimbela kahle ukukhanya okudukayo, kuthuthukise ukunemba. Idizayini yesakhiwo se-asymmetric in-axis scanning ct avele azungeze amaphuzu amathathu asemqoka: ukulungiselela ikhwalithi yesithombe, ukuqeda ukukhanya kwesibili, futhi kwandise ukukhanyiswa okukhanyayo.
Izakhi zayo eziphambili yilezi: A. IsigamekoUmthombo OkhanyayoB. Ukungena Slit C. Ukuqothula isibuko D. I-Grating E. Igxile kwi-Mirror F. Phuma (Slit) g.I-PhotoDETETETETECETETET
I-Spectroscope (Spectroscope) iyithuluzi lesayensi elibhidliza ukukhanya okuyinkimbinkimbi emigqeni yokubuka, equkethe ama-prisms noma ukugcwaliswa kokuphazamiseka, njll. Ukukhanya okunemibala eyisikhombisa elangeni yingxenye iso elinqunu lingahlukaniswa (ukukhanya okubonakalayo), kepha uma i-spectrometer iyokubola ilanga, ngokusho kwe-wavewth i-actrate, ngokwe-infrared, i-microwaviolet, i-x-ray nokunye. Ngokuthwebula imininingwane ekhanyayo yi-spectrometer, ukuthuthukiswa kwamapuleti wezithombe, noma ukubonisa okuzenzakalelayo kwamathuluzi okubonisana nezinombolo zokubonisa kanye nokuhlaziywa, ukuze uthole ukuthi yiziphi izinto eziqukethwe ku-athikili. Lobu buchwepheshe busetshenziswa kabanzi ekutholweni kokungcoliswa komoya, ukungcoliswa kwamanzi, inhlanzeko yokudla, imboni yensimbi nokunye.
