Hoʻomaka i nā kāmela Infrared
Ua lilo nā kāmeʻa infrared i mea hana koʻikoʻi ma nā ʻano ʻano like ʻole, mai ka hana kiʻi a me ka mahiʻai i ka pūʻali koa a me nā noi nānā. Hāʻawi kēia mau mea hana i nā mana kūʻokoʻa ma ka ʻike ʻana i ka mālamalama a i ʻole ka wela ma nā lōʻihi hawewe ma mua o ke kiko kikoʻī. ʻO nā ʻano kumu mua i loko o ka spectrum infrared, ʻo ia ka pōkole-wave infrared (SWIR), waena-wave infrared (MWIR), a me ka lōʻihi-wave infrared (LWIR). ʻO kā mākou manaʻo e hoʻomaopopo i ka ʻokoʻa ma waena o nā kāmela LWIR a me SWIR, e nānā ana i kā lākou ʻenehana, noi, a me nā pono.
Ka hoomaopopo ana i ka Infrared Spectrum
● Wehewehe a me ka laulā o nā lōʻihi nalu
Hoʻopili ka spectrum electromagnetic i kahi ākea o nā nalu nalu, mai nā kukuna gamma a i nā nalu lekiō. Noho ʻia ka mālamalama ʻike ʻia i kahi ʻāpana haiki, ma kahi o 0.4 a 0.7 micrometers. ʻOi aku ke kukui infrared ma waho o kēia pae mai kahi o 0.7 a 14 micrometer. ʻO ka SWIR maʻamau mai ka 0.7 a i ka 2.5 micrometers, aʻo LWIR ka uhi i ka 8 a 14 micrometer band.
● Hoʻohālikelike me ka Spectrum Māmā ʻIke ʻia
ʻOiai ua kaupalena ʻia ke kukui ʻike ʻia i kahi ʻāpana liʻiliʻi, hāʻawi ke kukui infrared i kahi ākea ʻoi aku ka nui no ka ʻike ʻana i nā ʻano like ʻole, me ka wela a me ke kukui ʻike ʻia. ʻAʻole like me ka mālamalama ʻike ʻia, hiki i nā nalu infrared ke komo i ka lepo, ka uahi, a me ka noe, e hāʻawi ana i nā pono kūʻokoʻa i nā hiʻohiʻona he nui.
Ua wehewehe ʻia nā kāmela SWIR
● Hana a me na ano nui
ʻIke nā kāmela SWIR i ke kukui infrared i ʻike ʻia mai nā mea, ʻaʻole ka wela a lākou e hoʻopuka ai. ʻO kēia hiʻohiʻona ka mea maikaʻi loa no ka hopu ʻana i nā kiʻi maʻemaʻe ʻoiai i nā kūlana kūlohelohe e like me ka noe a i ʻole ka pollution. ʻO nā kiʻi i hana ʻia e nā kāmeʻa SWIR e like pinepine me nā kiʻi ʻeleʻele-a-keʻokeʻo, e hāʻawi ana i ka mālamalama a me nā kikoʻī.
● Nā noi ma ka Mahiai a me Art
Loaʻa nā kāmela SWIR i nā noi nui i ka mahiʻai no ka nānā ʻana i ka maikaʻi o ka huahana, ʻike i nā hemahema o nā huaʻai a me nā mea kanu, a me ka hoʻomaʻamaʻa ʻana i ke kiʻi ʻana i ka pō. Hoʻohana ʻia lākou i ka honua no ka wehe ʻana i nā papa huna i nā kiʻi pena, hōʻoia i nā hana noʻeau, a ʻike i nā mea hoʻopunipuni. ʻO nā noi ʻē aʻe e pili ana i ka nānā uila, ka nānā ʻana o ka cell solar, a me ka ʻike kālā hoʻopunipuni.
Mea a me ka ʻenehana i nā kāmeʻa SWIR
● Indium Gallium Arsenide (InGaAs) a me nā mea ʻē aʻe
Ke hilinaʻi nui nei ka ʻenehana SWIR i nā mea holomua e like me Indium Gallium Arsenide (InGaAs), Germanium (Ge), a me Indium Gallium Germanium Phosphide (InGaAsP). Paʻa kēia mau mea i nā lōʻihi nalu ʻaʻole hiki ke ʻike ʻia e nā mea naʻau silicon-based, no laila pono lākou i nā kāmeʻa SWIR.
● Nā holomua ma SWIR Camera Technology
ʻO nā holomua hou i ka ʻenehana SWIR, e like me Sony's SenSWIR, e hoʻonui i ka laulā o ka naʻau mai ka ʻike ʻia i nā lōʻihi hawewe SWIR (0.4 a 1.7 µm). He hopena koʻikoʻi kēia mau holomua no ke kiʻi hyperspectral a me nā noi kūikawā ʻē aʻe. ʻOiai ʻo kēia mau hoʻomaikaʻi ʻana, pono e hoʻomaopopo ʻia ʻo kekahi mau mea ʻike SWIR, ʻoi aku ka nānā ʻana i nā sensor InGaAs, ua hoʻoponopono ʻia e nā kuʻikahi honua, e kaupalena ana i kā lākou loaʻa kālepa.
ʻO nā kāmela MWIR: Nā hiʻohiʻona a me nā hoʻohana
● ʻIke ʻana i ka hoʻoheheʻe wela ma ka waena-ʻaleʻa infrared
ʻIke nā kāmeʻa MWIR i ka pāhawewe wela i hoʻokuʻu ʻia e nā mea ma ka laulā 3 a 5 micrometer. He mea pono loa kēia mau kāmeʻa no ka ʻike ʻana i nā leaka kinoea, no ka mea hiki iā lākou ke hopu i nā hoʻokuʻu wela i ʻike ʻole ʻia e ka maka ʻōlohelohe.
● Koʻikoʻi i ka ʻike a me ka nānā ʻana i ke kinoea leak
He waiwai nui nā kāmeʻa MWIR i nā ʻoihana ʻenehana no ka ʻike ʻana i nā leaka kinoea ʻona. Hoʻohana ʻia lākou i nā noi palekana, e like me ka nānā ʻana i ka perimeter airport, ka nānā ʻana i nā moku moku, a me ka pale ʻana i nā ʻōnaehana koʻikoʻi. ʻO ko lākou hiki ke ʻike i nā pūlima wela e kūpono iā lākou no ka nānā ʻana i nā mīkini a me nā ʻōnaehana ʻē aʻe e hoʻohana ana i nā kinoea weliweli.
ʻO nā pono o nā kāmela MWIR
● Kūlana Kiʻekiʻe ma kekahi mau Kaiapuni
ʻO ka maikaʻi o nā kāmela MWIR aia i ko lākou hiki ke hāʻawi i nā pae ʻike lōʻihi, ma kahi o 2.5 mau manawa ʻoi aku ma mua olwir kameras. ʻO kēia hiki ke hoʻolilo iā lākou i mea kūpono no ka nānā lōʻihi a me ka nānā ʻana i nā noi.
● Hoʻohana i ka haʻahaʻa kiʻekiʻe a me nā ʻōnaehana kahakai
Hiki i nā kiʻi paʻi kiʻi MWIR ke hana maikaʻi i ka haʻahaʻa kiʻekiʻe a me nā kaiapuni kahakai, kahi e hakakā ai nā ʻano kamera ʻē aʻe. ʻO kā lākou hoʻolālā paʻa a māmā hoʻi e kūpono iā lākou no nā noi me nā koi ikaika, kaumaha, a me ka mana (SWaP), e like me nā hana ea.
ʻO nā kāmela LWIR a me kā lākou mau noi
● Long-Wave Infrared Detection and Thermal Emissions
ʻOi aku ka maikaʻi o nā kāmeʻa LWIR i ka ʻike ʻana i nā hoʻokuʻu wela ma ka laulā 8 a 14 micrometer. Hoʻohana nui ʻia lākou i nā hana pūʻali koa, ka nānā ʻana i nā holoholona hihiu, a me ka nānā ʻana i nā hale ma muli o ko lākou hiki ke ʻike i nā pūlima wela a hiki i ka pōʻeleʻele.
● Hoʻohana ma ka Koa, Ka Hoʻokolo ʻana i nā holoholona hihiu, a me ka nānā ʻana i nā hale
Ma nā hana pūʻali koa, pono nā kāmela LWIR no ka ʻike ʻana i nā mea hakakā ʻenemi a i ʻole nā kaʻa huna ma o nā lau. Hoʻohana ʻia lākou no nā noi ʻike pō a me ka ʻike ʻana i nā pōʻino alanui. Ma nā noi kīwila, hoʻohana nā mea nānā hale i nā kāmela LWIR e ʻike i nā wahi me ka insulation maikaʻi ʻole a i ʻole ka pōʻino wai.
ʻenehana ma hope o nā kāmela LWIR
● Mea Microbolometer e like me Vanadium Oxide
Hoʻohana pinepine nā kāmeʻa LWIR i nā microbolometers i hana ʻia me ka vanadium oxide (Vox) a i ʻole amorphous silicon (a-Si) e ʻike ai i nā hoʻokuʻu wela. Hoʻolālā ʻia kēia mau mea i mea liʻiliʻi i ka walaʻau wela, e ʻae ana i ka heluhelu ʻana o ka mahana.
● Nā pahupaʻikiʻi LWIR i hoʻoluʻu ʻole ʻia
Loaʻa nā kāmeʻa LWIR i ʻelua ʻano nui: ʻoluʻolu a me ka ʻole. Hāʻawi nā kāmeʻa LWIR i hoʻoluʻu ʻia i nā kikoʻī kiʻi kiʻekiʻe akā makemake i nā lako hoʻoluʻu kūikawā, e ʻoi aku ke kumukūʻai. ʻO nā kāmela LWIR uncooled, ma ka ʻaoʻao ʻē aʻe, hoʻohana maʻamau ʻia no ka nānā ʻana maʻamau, e hāʻawi ana i nā kikoʻī kūpono e ʻike ai i nā kānaka, holoholona, a i ʻole kaʻa.
Hoʻohālikelike Hoʻohālikelike: SWIR vs. MWIR vs. LWIR
● Nā ʻokoʻa nui i ka hana a me ka hoʻohana ʻana
ʻOi aku ka maikaʻi o nā kāmela SWIR i ke kiʻi ʻana i nā kiʻi i loko o nā kūlana kaiapuni paʻakikī ma ka ʻike ʻana i ka mālamalama i ʻike ʻia, e hoʻolilo iā lākou i mea kūpono no ka mahiʻai, ke kiʻi, a me ka nānā uila. ʻOi aku ka maikaʻi o nā kāmeʻa MWIR no ka ʻike ʻana i nā leaka kinoea a me ka nānā lōʻihi - He mea koʻikoʻi nā kāmela LWIR i ka pūʻali koa a me nā noi holoholona hihiu, hiki ke ʻike i nā hoʻokuʻu wela ma o nā lau a me ka pōʻeleʻele.
● Nā ikaika a me nā nāwaliwali o kēlā me kēia ʻano
ʻO nā kiʻi paʻi kiʻi SWIR he mea maʻalahi akā hiki ke kaupalena ʻia e nā hoʻoponopono honua. Hāʻawi nā kāmeʻa MWIR i ka ʻike lōʻihi-ʻokoʻa a ʻaʻole i hoʻopilikia ʻia e nā kūlana lewa akā pono paha nā ʻōnaehana hoʻomaha. Hāʻawi nā kāmeʻa LWIR i nā mana kiʻi wela maikaʻi akā hiki ke maʻalahi i ka walaʻau wela me ka ʻole o ka hoʻomaha ʻana.
Ke koho ʻana i ka pahupaʻikiʻi infrared pono
● Nā Manaʻo Ma muli o nā Pono Kūikawā
Ke koho ʻana i kahi kāmela infrared, pono e noʻonoʻo i nā koi kikoʻī o kāu noi. Inā pono ʻoe e nānā i nā huahana mahiʻai, e ʻike i ke kālā hoʻopunipuni, a i ʻole e wehe i nā ʻāpana huna i ke kiʻi, ʻo nā kāmela SWIR ke koho maikaʻi loa. No ka ʻike ʻana i ka leʻa kinoea a i ʻole ka nānā ʻana i ka lōʻihi-range nānā, kūpono nā kāmela MWIR. He kūpono nā kāmela LWIR no ka pūʻali koa, ka nānā ʻana i nā holoholona hihiu, a me nā nānā hale.
● Nānā i nā noi ʻoihana a me nā manaʻo
Loaʻa i nā ʻoihana like ʻole nā pono kūʻokoʻa e kuhikuhi i ke koho ʻana i nā kāmela infrared. Loaʻa nā ʻoihana mahiʻai, ʻenehana, a me nā ʻoihana uila mai ka hiki i nā kāmela SWIR ke hopu i nā kiʻi akaka i nā kūlana paʻakikī. Pono pinepine nā noi ʻoihana a me ka palekana i nā kāmela MWIR no ko lākou hiki ke ʻike lōʻihi. Ke hilinaʻi nei ka pūʻali koa, nā holoholona hihiu, a me nā noi nānā hale i nā kāmela LWIR no kā lākou hana kiʻi wela wela.
Ka hopena
ʻO ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o nā kāmela LWIR a me SWIR he mea koʻikoʻi ia no ke koho ʻana i ka hāmeʻa kūpono no kāu mau pono kikoʻī. Hāʻawi kēlā me kēia ʻano kāmela i nā pono kūʻokoʻa a me nā mea hiki, e lilo ai lākou i mea nui i nā ʻano āpau. Ma ka noʻonoʻo ʻana i nā koi kikoʻī o kāu noi, hiki iā ʻoe ke koho i ke kāmela infrared maikaʻi loa e hoʻokō i nā hopena maikaʻi loa.
