ʻO ke koi honua no nā hōʻikeʻike pālahalaha nui a kiʻekiʻe ke kūlana e hoʻokele i ka hana hou i ka ʻenehana hana. ʻO ke kikowaena o kēia ʻoihana ka hana nui ʻana o nā hōʻikeʻike me ka hoʻohana ʻana i ka ʻenehana Amorphous Silicon (a-Si). ʻOiai ua oʻo, ʻo ka hana ʻana o a-Si he pāʻani kiʻekiʻe kahi e nui ai ka hua, e kau ana i nā koi koʻikoʻi ma nā lako nānā i hoʻolālā ʻia e hōʻoia i ka pono o ka array. No nā mīkini i hana ʻia me ka hōʻoia ʻana i ka hana kūpono o kēlā me kēia pixel ma nā substrates aniani nui, ʻo ke kumu nā mea āpau. ʻO kēia kahi e hilinaʻi ai a me ke kūpaʻa paʻa o kakumu mīkini graniteNo ka hōʻike ʻana i ka papa pālahalaha, hoʻokomo ʻia ka nānā ʻana o ka pūʻulu silicon amorphous.
ʻO nā lako hana nānā ʻana o ka papa pālahalaha hou e hilinaʻi nei i nā ʻōnaehana optical a me nā ʻōnaehana uila paʻakikī e scan i nā wahi ākea a ʻike i nā hemahema microscopic. ʻO ka pololei o ke kūlana e pono ai no kēia mau mea hana nānā e hāʻule pinepine i loko o ka pae sub-micron. No ka hoʻokō ʻana i kēia, pono e kūkulu ʻia ka mea hana nānā holoʻokoʻa ma luna o kahi kahua i pale loa i nā ʻenemi maʻamau o ka pololei: ka hoʻonui ʻana o ka wela a me ka haʻalulu.
Ke Lanakila nei i ka Thermal Drift no ka Scanning Mau
I loko o kahi ʻano hana, ʻoiai kahi lumi maʻemaʻe i kāohi nui ʻia e ʻike i nā loli liʻiliʻi o ka mahana. Hoʻopili nui nā mea metala kuʻuna i kēia mau loli, e hoʻonui ana a ʻuʻuku paha i kahi hana i ʻike ʻia ʻo ka thermal drift. Hiki i kēia drift ke hana i ke kūlana pili o ka sensor nānā a me ka panela hōʻike e neʻe iki i ka wā o ka pōʻaiapuni scan, e alakaʻi ana i nā hewa geometric, nā heluhelu pololei ʻole, a me ka hopena, nā hemahema i hoʻokaʻawale hewa ʻia. Hiki i ka heluhelu wahaheʻe ke alakaʻi i ka hana hou ʻana i ke kumukūʻai nui a i ʻole ka ʻoki ʻana i kahi panela maikaʻi loa.
Aia ka hopena i nā waiwai mea kūlohelohe o ka granite kūlohelohe. ʻO ka hoʻohana ʻana i ka granite precision no ka nānā ʻana i ka papa pālahalaha amorphous silicon array e hāʻawi i kahi kahua me kahi Coefficient of Thermal Expansion (CTE) haʻahaʻa loa - ʻoi aku ka maikaʻi ma mua o ke kila a i ʻole ka alumini. Hōʻoia kēia inertia thermal e noho paʻa ka geometry koʻikoʻi o ka mīkini nānā i ka manawa a ma waena o nā ʻano mahana liʻiliʻi. Ma ka hoʻemi ʻana i ka thermal drift, hōʻoia ka granite i ke kaʻina hana nānā e kūlike, hiki ke hana hou ʻia, a hilinaʻi loa, e unuhi pololei ana i nā hua hana kiʻekiʻe.
ʻO ka mea hoʻopaʻa mālie: Damping Micro-Vibrations
Ma waho aʻe o nā hopena wela, ʻaʻole hiki ke kūkākūkā ʻia ke kūpaʻa ikaika o nā lako nānā. ʻO nā ʻano hana scan koʻikoʻi—e hoʻohana ana i nā motika linear wikiwiki a me nā bearings ea e hele i nā substrates aniani nui—e hoʻoulu i ka walaʻau mechanical kūloko. Eia kekahi, ʻo nā haʻalulu o waho mai nā ʻōnaehana HVAC o ka hale, nā mīkini kaumaha kokoke, a me nā hele wāwae hiki ke hoʻouna ma o ka papahele a hoʻopilikia i ke kaʻina hana nānā.
Loaʻa i ka Granite kahi mana damping kūloko kiʻekiʻe loa. ʻO kēia hiki ke omo koke a hoʻopau i ka ikehu mechanical ke kumu e hana ai kahi kumu mīkini granite no ka nānā ʻana i ka papa pālahalaha amorphous silicon array ma ke ʻano he mea hoʻokaʻawale haʻalulu hope loa. Ma kahi o ka hoʻoulu ʻana a i ʻole ka hoʻouna ʻana i nā haʻalulu e like me ka metala, hoʻololi koke ke ʻano crystalline mānoanoa o ka granite i kēia ikehu kinetic i ka wela liʻiliʻi, e hana pono ana i kahi kahua mālie loa a paʻa. He mea koʻikoʻi kēia no nā ʻōnaehana ʻike kiʻekiʻe e pono ai ka mālie koke e hopu i nā kiʻi ʻoi a pololei o nā hiʻohiʻona paʻakikī o ka array.
Hoʻomaka ka ʻoihana maikaʻi loa o ka ʻenekinia me ke kahua kūlohelohe
ʻAʻole wale ka pōhaku ʻinoʻino ka granite i koho ʻia no kēia mau kumu; he mea kiʻekiʻe ia, ʻo ia hoʻi ka granite ʻeleʻele, i hana pono ʻia a hoʻopau ʻia e hoʻokō i nā kūlana astronomical o ka pālahalaha a me ka pololei. Ma hope o ka ʻoki ʻana, ka wili ʻana, a me ka lapping, loaʻa i kēia mau kumu nā ʻae ʻana o ka ʻili i ana ʻia ma nā miliona o ka ʻīniha, e hana ana i kahi mokulele kuhikuhi metrology maoli.
ʻO kēia kūpaʻa i ke kūpaʻa a me ka pololei ma o ka hoʻohana ʻana i ka granite precision ka mea e hiki ai i nā mea hana o nā lako nānā silicon amorphous flat panel display e hoʻokuke i nā palena o ka hoʻonā a me ka throughput. Ma ka hoʻohui ʻana i kēia mea paʻa a paʻa, hōʻoia nā ʻenekinia ua kaupalena ʻia ka hana o ka mīkini e ka maikaʻi o kāna mau ʻāpana neʻe a me nā optics, ʻaʻole ma ka paʻa ʻole o kona ʻano kumu. I ka hoʻokūkū hoʻokūkū o ka hana hōʻike, ʻo ke koho ʻana i kahi kahua granite he hoʻoholo hoʻolālā e hōʻoiaʻiʻo ana i ka pololei lōʻihi a me ka maikaʻi o ka hana.
