He mea nui ka Spectrometers i ka noiʻi ʻepekema hou a me nā noi ʻoihana. No ka hoʻonui hou ʻana i kā lākou mau noi, ua noi nā mea noiʻi i kahi spectrometer ʻelua-kanal e hoʻokomo i ʻewalu subgratings, e pani ana i nā ʻāpana neʻe mechanical i hoʻohana ʻia i nā hoʻolālā kuʻuna. Hoʻohana ʻia ʻelua pūʻulu o quadrifold spectra no ka diffraction a me ke kiʻi ʻana ma ka mokulele kiko luna a me lalo o ka pahu pahu Dhyana 90A. ʻO ka maikaʻi nui o ke kāmela ma 400nm ma kahi o 90%. Ma waho aʻe o nā pono kūpono o ka ʻōnaehana spectroscopic, hiki i ka hoʻolālā paʻa o ka spectrometer ke ana like i nā kikoʻī he nui.
Fig 1 Hōʻike hoʻohālike o ka ʻōnaehana spectrometer. (a) ʻO S1 a me S2 nā ʻāpana ʻokoʻa kūʻokoʻa ʻelua. ʻO G1 a me G2 nā pūʻulu ʻelua o nā ʻāpana, ʻo kēlā me kēia me 4 sub-gratings. Hoʻopili ʻia nā laina kikoʻī 4-folded mai G1 a me G2 me ka hoʻonā kiʻekiʻe ma nā ʻaoʻao o luna a me lalo, ʻo ia hoʻi, o ka mokulele kiko o ka BSI-CMOS array detector. (b) Hoʻokahi pūʻulu o nā mea opi (S1, G1, nā aniani 1 a me 2, a me ka hui kānana F) i hoʻonohonoho ʻia i kiʻi ʻia nā laina kikoʻī o ke kahawai 1 ma ka ʻaoʻao o luna o ka mokulele kiko o ka BSI-CMOS detector D. ʻO nā kūlana hina-hina i hōʻike ʻia ma F1 a me F2 ma (a) he hakahaka (me nā kānana ʻole).
Fig 2 Paʻi kiʻi o ka spectrometer paʻa i kūkulu ʻia e like me ka hoʻolālā i manaʻo ʻia
ʻIkepili o ka ʻenehana kiʻi
Eia nō naʻe, pono nā spectrometers e ana i nā hōʻailona kukui ʻoi aku ma mua o hoʻokahi manawa i kekahi mau kūlana, ʻo ke ana ʻana o ka conventional detector i nā manawa like ʻole e pilikia i nā hewa pili i ka manawa a i ʻole nā hewa i hoʻohuli ʻia e ka hoʻololi ʻana i nā ala māmā. A paʻakikī ka hoʻohana ʻana i nā mea ʻike like ʻole e ʻike i ka pono quantum like me nā kūlana kaiapuni like ʻole. No laila, no ka lanakila ʻana i kēia mau pilikia, noiʻi nā mea noiʻi i kahi spectrometer compact novel i hoʻokumu ʻia ma Dhyana 90A. Hōʻike ka Dhyana 90A i kahi ākea ākea ākea (200-950 nm ka lōʻihi o ka nalu ʻike), kiʻekiʻe kiʻekiʻe (24 mau pahu i kēlā me kēia kekona), kiʻekiʻe hoʻonā (ʻoi aku ka maikaʻi ma mua o 0.1nm/pixel), a me kahi 16-bit kiʻekiʻe dynamic range. Ke manaʻo nei kēia hoʻohana ʻana i kahi mea ʻike kiʻekiʻe BSI-CMOS array ʻelua-dimensional i kaʻana like ʻia e nā ala kikoʻī he nui e hōʻike i kahi ʻano o ka hoʻomohala ʻana i ka spectrometer holomua.
