Spectrometers waa aalad muhiim u ah cilmi baarista sayniska casriga ah iyo codsiyada warshadaha. Si loo sii ballaadhiyo codsiyada kala duwan, cilmi-baarayaashu waxay soo jeediyeen spectrometer-ka laba-channel ah kaas oo ka kooban siddeed hoosaadyo, beddelaya qaybaha dhaqdhaqaaqa farsamada ee loo isticmaalo naqshadaha dhaqanka. Laba qaybood oo quadrifold spectra ah ayaa loo adeegsadaa kala-duwanaanshaha iyo sawirka diyaaradda sare iyo hoose ee kamarada Dhyana 90A, siday u kala horreeyaan. Hufnaanta tirada kamaradda ee 400nm waa qiyaastii 90%. Marka lagu daro faa'iidooyinka qiimaha wax ku oolka ah ee nidaamka spectroscopic, naqshadeynta is haysta ee spectrometer-ka ayaa awood u siinaya cabbirka isku mar ah ee spectra badan.
Jaantuska 1 Sawirka qaabaynta habka spectrometerka. (a) S1 iyo S2 waa laba indhood oo madax banaan. G1 iyo G2 waa laba qaybood oo gratings ah, mid walbana wuxuu ka kooban yahay 4 qaybood. Xariiqyada spectral ee 4-laaban ee ka socda G1 iyo G2 waxaa lagu sawiray xal sare oo ku saabsan qaybaha sare iyo hoose, siday u kala horreeyaan, ee diyaaradda xudunta u ah qalabka wax baadha ee BSI-CMOS. (b) Mid ka mid ah walxaha indhaha (S1, G1, muraayadaha 1 iyo 2, iyo filter set F) ayaa loo habeeyey sida xadhkaha spectral ee kanaalka 1 ay ku sawiran yihiin qaybta sare ee diyaaradda focal ee BSI-CMOS detector D. Meelaha midabka cawlan ee lagu muujiyay F1 iyo F2 ee (a) waa banaan yihiin (aan lahayn shaandhooyin)
Sawirka 2 Sawirka spectrometer-ka is haysta ee loo dhisay si waafaqsan naqshadda la soo jeediyay
Falanqaynta tignoolajiyada sawirka
Si kastaba ha ahaatee, spectrometers waxay u baahan yihiin inay cabbiraan wax ka badan hal calaamad oo iftiin isku mar ah xaaladaha qaarkood, Cabbirka baaraha caadiga ah ee waqtiyada kala duwan waxay la kulmi doontaa khaladaadka wakhtiga la xidhiidha ama khaladaadka ay keentay beddelidda waddooyinka iftiinka. Wayna adagtahay in la isticmaalo qalabka wax baara ee kala duwan si loo ogaado waxtarka tiro isku mid ah oo leh xaalado deegaan oo kala duwan. Sidaa darteed, si looga gudbo dhibaatooyinkan, cilmi-baarayaashu waxay daraasad ku sameeyeen spectrometer cusub oo is haysta kaas oo ku salaysan Dhyana 90A. Dhyana 90A waxa uu leeyahay muuqaal balaadhan oo kala duwan (200-950 nm dhererka hirarka la ogaanayo), xadiga qaabka sare (24 frames per second), xalin sare (oo ka wanaagsan 0.1nm/pixel), iyo 16-bit kala duwan firfircooni sare. Adeegsigan horumarsan oo laba-geesood ah oo BSI-CMOS ah oo baaraha soo diyaariya ee ay wadaagaan kanaalo muuqaal-muuqaal ah ayaa rajaynaya inay metelaan isbeddel mustaqbalka ee horumarka spectrometer-ka sare.
