Kuʻuna hana
Hoʻokumu ʻia ka mālamalama kūlohelohe i nā nalu māmā me nā lōʻihi nalu like ʻole.ʻO ka laulā i ʻike ʻia e ka maka kanaka he 390-780nm.ʻAʻole hiki ke ʻike ʻia nā hawewe electromagnetic ma mua o 390nm a ʻoi aku ka lōʻihi ma mua o 780nm.Ma waena o lākou, aia nā hawewe electromagnetic me ka lōʻihi haʻahaʻa ma lalo o 390nm ma waho o ka violet o ka spectrum māmā ʻike ʻia a ua kapa ʻia nā hihi ultraviolet;ʻO nā hawewe electromagnetic ʻoi aku ka lōʻihi ma mua o 780nm ma waho o ka ʻulaʻula o ka spectrum māmā ʻike ʻia a ua kapa ʻia ʻo infrared, a ʻo ko lākou lōʻihi hawewe mai 780nm a 1mm.
ʻO ka infrared he nalu electromagnetic me ka lōʻihi o ka nalu ma waena o nā microwaves a me ka mālamalama ʻike ʻia, a he ʻano like kona ʻano me nā hawewe lekiō a me ka mālamalama ʻike ʻia.Ma ke ʻano, ʻo nā mea āpau i ʻoi aku ka kiʻekiʻe o ka mahana ma mua o ka ʻole loa (-273.15°C) e hoʻomālamalama mau i nā kukuna infrared.Ua kapa ʻia kēia hanana i ka radiation thermal.Hoʻohana ka ʻenehana kiʻi wela infrared i ka micro thermal radiation detector, optical imaging imaging a me ka opto-mechanical scanning system e loaʻa ai nā hōʻailona hoʻoheheʻe infrared o ka mea e ana ʻia, a ʻike ʻia ke ʻano o ka hāʻawi ʻana i ka ikehu infrared i ka mea photosensitive o ka mea ʻike infrared. ma hope o ka kānana spectral a me ka kānana spatial, ʻo ia hoʻi, ʻo ke kiʻi wela infrared o ka mea i ana ʻia e nānā ʻia a nānā ʻia i ka ʻāpana a i ʻole spectroscopic detector, ua hoʻololi ʻia ka ikehu infrared e ka mea ʻike i ka hōʻailona uila, i hoʻonui ʻia a hoʻololi ʻia i ke wikiō maʻamau. hōʻailona, a hōʻike ʻia e like me ke kiʻi wela infrared ma ka pale TV a i ʻole ka nānā ʻana.
ʻO ka infrared he nalu electromagnetic me ke ʻano like me nā hawewe lekiō a me ke kukui ʻike ʻia.ʻO ka loaʻa ʻana o ka infrared he lele i ka ʻike kanaka i ke ʻano.ʻO ka ʻenehana e hoʻohana ana i kahi mea uila kūikawā e hoʻololi i ka hāʻawi ʻana i ka wela ma ka ʻili o kahi mea i ke kiʻi i ʻike ʻia e ka maka o ke kanaka a hōʻike i ka hāʻawi ʻana i ka wela ma ka ʻili o ka mea i nā kala like ʻole i kapa ʻia ʻo ka ʻenehana infrared thermal imaging.Ua kapa ʻia kēia mea uila he infrared thermal imager.
Hoʻohana ka mea kiʻi wela infrared i ka mea ʻike infrared, optical imaging object a me opto-mechanical scanning system (ʻo ka ʻenehana hoʻokele holomua o kēia manawa e hoʻopau i ka ʻōnaehana opto-mechanical scanning) no ka loaʻa ʻana o ke ʻano hoʻohele ikehu infrared radiation o ka mea e ana ʻia a hōʻike ʻia i ka mea paʻi kiʻi o ka mea ʻike infrared.Ma waena o ka ʻōnaehana ʻōpika a me ka mea ʻike infrared, aia kahi ʻano hoʻoheheʻe optical-mechanical (ʻaʻole i loaʻa kēia ʻano hana i ka focal plane thermal imager) no ka nānā ʻana i ke kiʻi wela infrared o ka mea e ana ʻia a kālele iā ia ma ka ʻāpana a i ʻole ka mea ʻike spectroscopic. .Hoʻololi ʻia ka ikehu infrared i nā hōʻailona uila e ka mea ʻike, a hōʻike ʻia ke kiʻi wela infrared ma ka pale TV a i ʻole ka nānā ʻana ma hope o ka hoʻonui ʻana a me ka hoʻololi ʻana i ka hōʻailona wikiō maʻamau.
ʻO kēia ʻano kiʻi wela e pili ana i ke kahua mahele wela ma ka ʻili o ka mea;ʻo ka mea nui, ʻo ia ke kiʻi puʻupuʻu wela o ka pāhawewe infrared o kēlā me kēia ʻāpana o ka mea e ana ʻia.Ma muli o ka nāwaliwali loa o ka hōʻailona, ke hoʻohālikelike ʻia me ke kiʻi māmā ʻike ʻia, nele ka gradation a me ke kolu o ke ana.I mea e hoʻokolokolo ai i ka māhele wela infrared o ka mea e ana ʻoi aku ka maikaʻi i ke kaʻina hana maoli, ua hoʻohana pinepine ʻia kekahi mau mea kōkua e hoʻonui i nā hana kūpono o ka mea kani, e like me ka hoʻomalu ʻana o ka ʻōlinolino kiʻi a me ka ʻokoʻa, maʻamau maoli. ka hoʻoponopono ʻana, ke kaha kiʻi kala wahaheʻe a me ka histogram no nā hana makemakika, paʻi, etc.
Ke hoʻohiki nei nā kāmela kiʻi wela i ka ʻoihana pilikia
Ke hoʻohālikelike ʻia me nā kāmeʻa māmā ʻike kuʻuna e hilinaʻi nei i ke kukui kūlohelohe a i ʻole ambient no ka nānā ʻana i ka pahupaʻikiʻi, ʻaʻole pono nā kiʻi kiʻi thermal i kahi kukui, a hiki ke kiʻi maopopo i ka hilinaʻi ʻana i ka wela infrared i hoʻomālamalama ʻia e ka mea ponoʻī.He kūpono ka pahupaʻi kiʻi thermal no kēlā me kēia wahi kukui a ʻaʻole pili i ka mālamalama ikaika.Hiki iā ia ke ʻike maopopo a loaʻa i nā pahu hopu, a ʻike i nā mea i hoʻokaʻawale ʻia a huna ʻia me ka nānā ʻole i ke ao a me ka pō.No laila, hiki iā ia ke ʻike maoli i ka nānā ʻana i nā hola 24.
