Ama-Spectrometers ayithuluzi elibalulekile ocwaningweni lwesayensi lwesimanje kanye nezinhlelo zokusebenza zezimboni. Ukuze baqhubeke bandise ububanzi bezinhlelo zabo zokusebenza, abacwaningi benze isiphakamiso se-spectrometer eneziteshi ezimbili ezihlanganisa izingxenye ezingaphansi eziyisishiyagalombili, esikhundleni sezingxenye ezihambayo ezisetshenziswa emiklameni evamile. Amasethi amabili we-spectra ephindwe kane asetshenziselwa i-diffraction kanye nesithombe endizeni egxile phezulu nephansi yekhamera ye-Dhyana 90A, ngokulandelanayo. Ukusebenza kahle kwe-quantum kwekhamera ku-400nm cishe kungama-90%. Ngaphezu kwezinzuzo ezingabizi kakhulu zesistimu ye-spectroscopic, idizayini ehlangene ye-spectrometer inika amandla ukulinganisa ngesikhathi esisodwa kwe-spectra eminingi.
Umdwebo 1 Umdwebo wohlelo lwesistimu ye-spectrometer. (a) I-S1 ne-S2 yizicucu ezimbili ezizimele. I-G1 kanye ne-G2 amasethi amabili egridi, ngalinye liqukethe ama-sub-gratings angu-4. Imigqa ye-spectral egoqiwe engu-4 esuka ku-G1 kanye ne-G2 iboniswe ngokulungiswa okuphezulu ezingxenyeni ezingenhla nezingezansi, ngokulandelana, zendiza egxile yomtshina we-BSI-CMOS wamalungu afanayo. (b) Isethi eyodwa yezinto ezibonakalayo (i-S1, G1, izibuko 1 no-2, kanye nesethi yokuhlunga F) ihlelwa ngendlela yokuthi imigqa ye-spectral yesiteshi 1 ibe nesithombe engxenyeni engenhla yendiza egxilile yomtshina we-BSI-CMOS D. Izindawo ezinombala ompunga eziboniswe ku-F1 kanye no-F2 kokuthi (a) azinalutho (ngaphandle kokuhlunga)
Umfanekiso wesi-2 Isithombe se-compact spectrometer esakhiwe ngokuhambisana nomklamo ohlongozwayo
Ukuhlaziywa kobuchwepheshe bezithombe
Kodwa-ke, ama-spectrometer adinga ukukala amasignali okukhanya angaphezu kweyodwa ngesikhathi esifanayo kwezinye izimo, ukulinganisa komtshina okuvamile ngezikhathi ezihlukene kuzobhekana namaphutha ahlobene nesikhathi noma amaphutha adangwe ukushintsha imizila yokukhanya. Futhi kunzima ukusebenzisa imitshina ehlukene ukubona ukusebenza kahle kwe-quantum ngezimo ezihlukene zemvelo. Ngakho-ke, ukuze banqobe lobu bunzima, abacwaningi bacwaninga inoveli ye-compact spectrometer esekelwe ku-Dhyana 90A. I-Dhyana 90A ihlanganisa ububanzi be-spectral obubanzi (ubude bokubona obungu-200-950 nm), izinga eliphezulu lozimele (amafreyimu angu-24 ngomzuzwana), ukulungiswa okuphezulu (okungcono kuno-0.1nm/ pixel), kanye nobubanzi obuguquguqukayo obuphezulu obungu-16-bit. Lokhu kusetshenziswa komtshina wamalungu afanayo we-BSI-CMOS onezinhlangothi ezimbili ezithuthukisiwe okwabelwana ngawo amashaneli amaningi e-spectral kuthemba ukumela inkambiso yesikhathi esizayo yokuthuthukiswa kwe-spectrometer ethuthukisiwe.
