I-Spectrometers sisixhobo esiphambili kuphando lwenzululwazi yanamhlanje kunye nokusetyenziswa kwezoshishino. Ukwandisa ngakumbi uluhlu lwabo lwezicelo, abaphandi bacebise i-spectrometer ye-double-channel edibanisa i-subgratings esibhozo, ithatha indawo yeendawo ezihambayo zoomatshini ezisetyenziswa kuyilo lwemveli. Iiseti ezimbini ze-quadrifold spectra zisetyenziselwa i-diffraction kunye nemifanekiso kwi-plane ephezulu nasezantsi yekhamera ye-Dhyana 90A, ngokulandelelanayo. Ukusebenza kwe-quantum yekhamera kwi-400nm malunga ne-90%. Ukongeza kwiinzuzo ezingabizi kakhulu zenkqubo ye-spectroscopic, i-compact design ye-spectrometer yenza ukulinganisa kwangaxeshanye kwee-spectra ezininzi.
Isazobe soku-1 Umzobo weskimu wenkqubo ye-spectrometer. (a) I-S1 kunye ne-S2 zi-slits ezimbini ezizimeleyo zamehlo. I-G1 kunye ne-G2 ziiseti ezimbini ze-gratings, nganye iqulethe i-4 sub-gratings. Imigca ye-spectral ene-4-folded from G1 kunye ne-G2 ifanekiselwa ngesisombululo esiphezulu kwiindawo eziphezulu kunye nezantsi, ngokulandelanayo, kwi-focal plane ye-BSI-CMOS i-array detector. (b) Iseti enye yezinto ezibonakalayo (i-S1, i-G1, izibuko 1 kunye no-2, kunye neseti yokucoca u-F) icwangciswe ngendlela yokuba imigca ebonakalayo yetshaneli 1 iboniswe kwindawo ephezulu yendiza ye-BSI-CMOS detector D. Izikhundla ezinombala ongwevu eziboniswe kwi-F1 kunye ne-F2 kwi-(a) ayinanto (ngaphandle kokucoca)
Umfanekiso wesi-2 Ifoto ye-compact spectrometer eyenziwe ngokuhambelana noyilo olucetywayo
Uhlalutyo lweteknoloji yokucinga
Nangona kunjalo, ii-spectrometers kufuneka zilinganise iimpawu zokukhanya ezingaphezu kwesinye ngexesha elifanayo kwezinye iimeko, umlinganiselo oqhelekileyo we-detector ngamaxesha ahlukeneyo uya kubandezeleka ngenxa yeempazamo ezinxulumene nexesha okanye iimpazamo ezibangelwa kukutshintsha iindlela zokukhanya. Kwaye kunzima ukusebenzisa ii-detectors ezahlukeneyo ukuqonda ubungakanani obufanayo be-quantum kunye neemeko ezahlukeneyo zokusingqongileyo. Ke ngoko, ukoyisa obu bunzima, abaphandi bafunda inoveli ye-compact spectrometer esekwe kwi-Dhyana 90A. I-Dhyana 90A ibonisa uluhlu olubanzi lwe-spectral (i-200-950 nm ukubonwa kwe-wavelength), izinga eliphezulu lefreyimu (iifreyimu ezingama-24 ngesekhondi), isisombululo esiphezulu (ngcono kune-0.1nm / pixel), kunye ne-16-bit high dynamic range. Oku kusetyenziswa kwesixhobo esiphambili esinamacala amabini e-BSI-CMOS ekwabelwana ngaso ngamajelo amaninzi okubonwayo sinethemba lokumela intsingiselo yexesha elizayo yophuhliso lwe-spectrometer ephezulu.
