25/08/08Ma ke kiʻi ʻenehana a me ka ʻepekema, ʻo ka hopu ʻana i nā mea holo wikiwiki ma lalo o ke kukui haʻahaʻa he paʻakikī mau. ʻO ia kahi e komo ai nā kāmeʻa Time Delay Integration (TDI). Hoʻohui ka ʻenehana TDI i ka hoʻonohonoho ʻana i ka neʻe a me nā hōʻike lehulehu e hāʻawi i ka naʻau a me ka mālamalama o nā kiʻi, ʻoi aku ka nui o nā kaiapuni kiʻekiʻe.
He aha ke kāmela TDI?
ʻO kahi pahupaʻi kiʻi TDI he pahupaʻi kiʻi laina kūikawā e hopu i nā kiʻi o nā mea neʻe. ʻAʻole like me nā kiʻi paʻi kiʻi wahi maʻamau e hōʻike ana i kahi kiʻi holoʻokoʻa i ka manawa hoʻokahi, hoʻololi nā pahu kiʻi TDI i ka hoʻopiʻi mai kahi lālani o nā pika a i kahi aʻe e like me ka neʻe o ka mea. ʻO kēlā me kēia lālani pixel e hōʻiliʻili i ka mālamalama i ka neʻe ʻana o ke kumuhana, me ka hoʻonui ʻana i ka manawa hōʻike a hoʻonui i ka ikaika hōʻailona me ka hoʻokomo ʻole ʻana i ka motion blur.
Hoʻonui nui kēia hoʻohui kālā i ka ratio signal-to-noise (SNR), e hana ana i nā kāmeʻa TDI i kūpono no nā noi kiʻekiʻe a i ʻole nā kukui haʻahaʻa.
Pehea e hana ai kahi kāmela TDI?
Hōʻike ʻia ka hana ʻana o kahi kāmela TDI ma ke Kiʻi 1.
Kiʻi 1: Ka hana ʻana o nā mea ʻike hoʻohui manawa lōʻihi (TDI).
HOOLAHA: Ua hoʻoneʻe nā kāmela TDI i nā kumukūʻai ma waena o nā 'pae' he nui i ka hoʻonohonoho ʻana me kahi kumuhana kiʻi neʻe. Hāʻawi kēlā me kēia pae i kahi manawa hou e ʻike ai i ka mālamalama. Hōʻike ʻia ma o kahi 'T' ʻālohilohi e neʻe ana ma luna o kahi pahupaʻikiʻi, me kahi ʻāpana 5-kolume a 5-pae o kahi sensor TDI. ʻO Tucsen Dhyana 9KTDI me ka neʻe ʻana o ke ʻano o ke ʻano CCD hybrid akā ʻo ka heluhelu like ʻana o ke ʻano CMOS.
ʻO nā kāmeʻa TDI he mau kiʻi kiʻi laina laina, me kahi ʻokoʻa koʻikoʻi: ma kahi o hoʻokahi lālani pixel e loaʻa ai ka ʻikepili i ka nānā ʻia ʻana o nā kiʻi kiʻi ma kahi kumuhana kiʻi, he nui nā lālani o nā pahu kiʻi TDI, i kapa ʻia ʻo 'stages', a hiki i ka 256 maʻamau.
Akā naʻe, ʻaʻole hana kēia mau lālani i kiʻi 2-dimensional e like me kahi pahupaʻi kiʻi wahi. Akā, i ka neʻe ʻana o ke kumuhana kiʻi i nānā ʻia ma ka ʻaoʻao o ke kiʻi paʻi kiʻi, ʻo nā photoelectrons i ʻike ʻia i loko o kēlā me kēia pixel shuffle a hiki i ka lālani aʻe e like me ka neʻe ʻana o ke kumuhana kiʻi, me ka heluhelu ʻole ʻia. Hāʻawi kēlā me kēia lālani hou i kahi manawa hou e hōʻike i ke kumuhana kiʻi i ka mālamalama. Hoʻokahi wale nō ʻāpana kiʻi i hiki i ka lālani hope o nā pika o ka mea ʻike, ʻo ia ka lālani, a laila hāʻawi ʻia i ka papa hana heluhelu no ke ana ʻana.
No laila, ʻoiai nā ana he nui e hana ʻia ana ma nā ʻanuʻu kāmela, hoʻokahi wale nō hiʻohiʻona o ka leo heluhelu heluhelu kamera i hoʻokomo ʻia. Mālama ka pahupaʻikiʻi TDI 256-pae i ka laʻana i ka nānā ʻana he 256 manawa lōʻihi, a no laila he 256 mau manawa lōʻihi o ka hōʻike ʻana ma mua o ka pahu kiʻi kiʻi laina like. ʻO ka manawa hoʻolaha like me kahi pahupaʻi kiʻi ʻāpana e hāʻawi i ka ʻoniʻoni ʻoi loa, e lilo ai ke kiʻi i mea ʻole.
I ka manawa hea e hoʻohana ʻia ai ka TDI?
ʻO nā pahupaʻikiʻi TDI kahi hopena maikaʻi loa no kēlā me kēia noi kiʻi kahi e neʻe ai ke kumuhana kiʻi e pili ana i ka pahupaʻikiʻi, me ka hāʻawi ʻana i ke ʻano o ka neʻe ʻana ma ka ʻike o ke kāmela.
No laila, ua komo nā noi o ke kiʻi TDI, ma ka ʻaoʻao hoʻokahi, nā mea a pau o ka nānā ʻana i ka laina kahi i hoʻokumu ʻia ai nā kiʻi 2-dimensional, ʻoiai e lawe mai ana i ka wikiwiki, ʻoi aku ka maikaʻi o ka ʻike haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ke kiʻi, a i ʻole nā mea ʻekolu i ka manawa hoʻokahi. Ma ka ʻaoʻao ʻē aʻe, nui nā ʻenehana kiʻi e hoʻohana ana i nā kāmeʻa wahi-scan kahi e hoʻohana ʻia ai nā kāmela TDI.
No ka sCMOS TDI ki'eki'e, hiki ke ho'ohana 'ia ke ki'i 'tile and stitch' i loko o ka microscopy fluorescence biological me ka ho'ohana 'ana i ka nānā 'ana i ke kahua ma kahi o ka tile. A i ʻole hiki ke kūpono nā TDI āpau i nā noi nānā. ʻO kekahi noi koʻikoʻi no ka TDI ʻo ia ke kiʻi ʻana i ka cytometry kahe, kahi e loaʻa ai nā kiʻi fluorescence o nā cell i ko lākou hele ʻana i kahi pahupaʻikiʻi i ka wā e kahe ana ma kahi kahawai microfluidic.

Laʻana: Paheʻe a me ka Multi-Well Plate Scanning
E like me ka mea i ʻōlelo ʻia, hoʻokahi noi me ka ʻōlelo hoʻohiki koʻikoʻi no nā kāmela sCMOS TDI e humuhumu ana i nā noi, me ka slide a i ʻole ka nānā ʻana i ka pā nui. ʻO ka nānā ʻana i nā laʻana microscopy fluorescent a i ʻole brightfield microscopy me nā pahupaʻikiʻi ʻāpana 2-dimensional e hilinaʻi ʻia i ke humuhumu ʻana i nā kiʻi i hoʻokumu ʻia mai nā neʻe he nui o ke kahua microscope XY. Pono kēlā me kēia kiʻi i ke kahua e kū, hoʻoponopono, a laila hoʻomaka hou, me ka lohi o ka pani pani. ʻO TDI, ma kekahi ʻaoʻao, hiki ke loaʻa nā kiʻi i ka wā e neʻe ana ke kahua. Hoʻokumu ʻia ke kiʻi mai kahi helu liʻiliʻi o nā 'ʻili' lōʻihi, e uhi ana kēlā me kēia i ka laula holoʻokoʻa o ka hāpana. Hiki i kēia ke alakaʻi i ka wikiwiki o ka loaʻa ʻana o ka ʻikepili i nā noi humuhumu a pau, e pili ana i nā kūlana kiʻi.
ʻO ka wikiwiki o ka neʻe ʻana o ke kahua e like me ka nui o ka manawa hōʻike o ke kāmela TDI, no laila ʻo nā manawa hōʻike pōkole (1-20ms) e hāʻawi i ka hoʻomaikaʻi maikaʻi loa i ka wikiwiki kiʻi i hoʻohālikelike ʻia me nā kāmela scan wahi, a laila hiki ke alakaʻi i kahi kauoha o ka nui a i ʻole ka hōʻemi ʻana i ka manawa loaʻa.

Ka hoʻonohonoho like ʻana i ka TDI
He mea nui ka hoʻonohonoho ʻana o kahi pahupaʻikiʻi TDI me ke kumuhana kiʻi (i loko o kekahi mau pākēneka) - ʻo ka velocity mismatch e alakaʻi i kahi hopena 'motion blur'. Hiki ke hana ʻia kēia synchronization i ʻelua ala:

FAQ
Hiki i nā kāmela TDI ke hana ma ke ʻano scan wahi?
Hiki i nā kāmeʻa TDI ke hana i nā kiʻi 2-dimensional (ʻoi aku ka lahilahi) i ke ʻano 'area-scan-like', i loaʻa ma o ka hoʻopunipuni o ka manawa ʻike. Hiki ke kōkua i nā hana e like me ka nānā ʻana a me ka alignment.
No ka ho'omaka 'ana i ka 'area-scan exposure', 'ho'oma'ema'e mua'ia ka mea 'ike ma ka ho'onui 'ana i ka TDI ma ka li'ili'i loa e like me ka nui o nā 'anu'u e like me nā pae o ka pahupa'iki'i, e like me ka hikiwawe loa, a laila kū. Loaʻa ʻia kēia ma o ka mana lako polokalamu, a i ʻole ka hoʻoulu ʻana i nā lako, a hana maikaʻi ʻia i ka pōʻeleʻele. No ka laʻana, pono e heluhelu ka pahupaʻikiʻi 256 ma kahi o 256 mau laina, a laila e kū. Hoʻolei ʻia kēia 256 laina o ka ʻikepili.
ʻOiai ʻaʻole hoʻāla ʻia ka pahupaʻikiʻi a heluhelu ʻia paha nā laina, ʻano like ka mea ʻike e like me kahi ʻāpana-scan sensor e hōʻike ana i kahi kiʻi.
A laila e hala ka manawa hoʻolaha i makemake ʻia me ka pahupaʻikiʻi ʻole, ma mua o ka neʻe hou ʻana i ka pahupaʻikiʻi ma ka liʻiliʻi o kona helu o nā pae, e heluhelu ana i kēlā me kēia laina o ke kiʻi i loaʻa. Eia hou, ʻoi aku ka maikaʻi o kēia māhele 'heluhelu' i ka pōʻeleʻele.
Hiki ke hana hou ʻia kēia ʻenehana no ka hāʻawi ʻana i kahi 'nānā mua' a i ʻole ke kaʻina o nā kiʻi wahi-scan me ka liʻiliʻi o ka distortion a me ka blurring mai ka hana TDI.
