Imikorere ya optique ya fibre optique

Ububiko bwa fibre optique busanzwe bukoresha fibre optique nkibimenyetso bifatika, bizaba bifotora bifatanye na ecran kugirango isesengurwe.Bitewe nuburyo bworoshye bwa fibre optique, abayikoresha barashobora guhinduka cyane kugirango bubake sisitemu yo kugura ibintu.

Ibyiza bya fibre optique ya sprometrike ni modularité na flexible ya sisitemu yo gupima.Microoptique ya fibre optiquekuva MUT mu Budage birihuta cyane kuburyo bishobora gukoreshwa mubisesengura kumurongo.Kandi kubera gukoresha ibikoresho bidahenze bya disiketi rusange, igiciro cya spekrometrike kiragabanuka, bityo ikiguzi cya sisitemu yose yo gupima iragabanuka.

Iboneza shingiro rya fibre optique ya sprometrike igizwe no gusya, gucamo, na detector.Ibipimo byibi bice bigomba gutomorwa mugihe uguze ecran.Imikorere ya spekrometero iterwa no guhuza neza no guhinduranya ibyo bice, nyuma yogusuzuma kwa fibre optique ya optique, mubisanzwe, ibyo bikoresho ntibishobora kugira icyo bihindura.

Intangiriro

Grating

Guhitamo gushimira biterwa nurwego rwerekanwe nibisabwa kugirango bikemuke.Kuri fibre optique ya fibre optique, urwego rwerekana ubusanzwe ruri hagati ya 200nm na 2500nm.Bitewe nibisabwa kurwego rwo hejuru, biragoye kubona intera yagutse;Mugihe kimwe, urwego rwo hejuru rwo gukemura ibisabwa, urumuri ruke.Kubisabwa mubisubizo byo hasi no kwaguka kwagutse, umurongo wa 300 / mm gusya nibyo bisanzwe.Niba hagomba gukemurwa icyerekezo kinini cyane, birashobora kugerwaho muguhitamo urusyo rufite imirongo 3600 / mm, cyangwa ugahitamo disiketi ifite ibyemezo byinshi bya pigiseli.

ibice

Igice kigufi gishobora kunoza imyanzuro, ariko urumuri rutemba ni ruto;Kurundi ruhande, ibice binini birashobora kongera sensibilité, ariko bitwaye ibisubizo.Mubisabwa bitandukanye mubisabwa, ubugari bukwiye bwatoranijwe kugirango hongerwe ibisubizo rusange.

iperereza

Detector muburyo bumwe na bumwe igena imiterere nubukangurambaga bwa fibre optique ya sprometrike, agace korohereza urumuri kuri detector ntigisanzwe, igabanijwemo pigiseli ntoya kugirango ikemurwe cyane cyangwa igabanijwemo pigiseli nkeya ariko nini kugirango yumve neza.Mubisanzwe, ibyiyumvo bya detektori ya CCD nibyiza, urashobora rero kubona igisubizo cyiza nta sensitivite kurwego runaka.Kubera ubukangurambaga bukabije hamwe n’urusaku rw’ubushyuhe bwa disiketi ya InGaAs hafi ya infragre, igipimo cyerekana ibimenyetso-urusaku rwa sisitemu gishobora kunozwa neza hakoreshejwe firigo.

Akayunguruzo

Kuberako ibikorwa byinshi bitandukanya ingaruka ubwayo, interineti yo gutandukanya ibintu byinshi irashobora kugabanuka ukoresheje akayunguruzo.Bitandukanye na sprometrike isanzwe, fibre optique yometse kuri detekeri, kandi iki gice cyimikorere kigomba gushyirwaho mumuganda.Muri icyo gihe, igifuniko nacyo gifite imikorere yo kurwanya-kugaragariza no kunoza igipimo cyerekana-urusaku rwa sisitemu.

Imikorere ya spekrometrike igenwa cyane cyane nurwego rwerekanwe, gukemura neza no kumva.Guhindura kuri kimwe muri ibyo bipimo mubisanzwe bizagira ingaruka kumikorere yibindi bipimo.

Ikibazo nyamukuru cya spekrometrike ntabwo ari ukugereranya ibipimo byose mugihe cyo gukora, ahubwo ni ugukora ibipimo bya tekiniki ya spekrometrike byujuje ibisabwa kugirango ukore ibisabwa muri ubu buryo butatu bwo guhitamo umwanya.Izi ngamba zifasha spekrometero guhaza abakiriya kugaruka kwinshi hamwe nishoramari rito.Ingano ya cube iterwa nibipimo bya tekinike spekrometrike igomba kugeraho, kandi ubunini bwayo bujyanye no kugorana kwa spekrometrike hamwe nigiciro cyibicuruzwa.Ibicuruzwa bya Spectrometer bigomba kuba byujuje ibipimo bya tekiniki bisabwa nabakiriya.

Urutonde

Ikirangantegohamwe na bito bito byerekana ubusanzwe bitanga amakuru arambuye, mugihe intera nini nini yagutse.Kubwibyo, urutonde rwikigereranyo ni kimwe mubintu byingenzi bigomba gutomorwa neza.

Ibintu bigira ingaruka kumurongo ni cyane cyane gusya no gushakisha, hamwe no gusya hamwe na detector bihuye byatoranijwe ukurikije ibisabwa bitandukanye.

ibyiyumvo

Tuvuze ibyiyumvo, ni ngombwa gutandukanya sensibilité muri Photometrie (imbaraga ntoya yerekana ko aIkigereranyoIrashobora gutahura) hamwe no kwiyumvisha ibintu muri stoichiometry (itandukaniro rito mu kwinjiza ibintu bishobora gupima).

a.Kwiyumvisha amafoto

Kuri porogaramu zisaba ibyiyumvo bihanitse cyane, nka fluorescence na Raman, turasaba SEK ya termo-ikonje ya optique fibre spekrometrike hamwe na 1010 pigiseli ikonjesha ya 1024 pigiseli ebyiri zerekana ibyuma bya CCD, hamwe na disiketi yerekana lens, indorerwamo za zahabu, hamwe nuduce twinshi ( 100μm cyangwa mugari).Iyi moderi irashobora gukoresha igihe kirekire cyo kwishyira hamwe (kuva kuri milisegonda 7 kugeza kuminota 15) kugirango itezimbere imbaraga za signal, kandi irashobora kugabanya urusaku no kunoza intera.

b.Stoichiometric sensitivite

Kugirango umenye indangagaciro zibiri zo kwinjizwa hamwe na amplitude yegeranye cyane, ntibisabwa gusa sensibilité ya detector, ahubwo biranakenewe igipimo cyerekana-urusaku.Detector ifite igipimo kinini cyerekana-urusaku ni firigo ya firigo ya firigo 1024-pigiseli ebyiri-yerekana ibyuma bibiri bya CCD ikurikirana muri SEK spectrometer ifite ibimenyetso byerekana urusaku 1000: 1.Impuzandengo y'amashusho menshi yerekana irashobora kandi kunoza igipimo cyerekana-urusaku, kandi kwiyongera k'umubare ugereranije bizatera igipimo cyerekana-urusaku kwiyongera kumuvuduko wa kare, urugero, impuzandengo yikubye inshuro 100 ongera igipimo cyerekana-urusaku inshuro 10, ugere 10,000: 1.

Icyemezo

Gukemura neza ni ikintu cyingenzi cyo gupima ubushobozi bwo gutandukanya optique.Niba ukeneye optique yo hejuru cyane, turagusaba ko wahitamo urusyo rufite imirongo 1200 / mm cyangwa irenga, hamwe nigice gito hamwe na 2048 cyangwa 3648 pigiseli ya CCD.
