I ka wā post-epidemic, ke manaʻoʻiʻo nei mākou he mea nui nā sensor infrared i kēlā me kēia lā. I ke kaʻina o ka hele ʻana, pono mākou e hele hou i ke ana wela ma mua o ka hiki ʻana i ko mākou wahi e hele ai. Ma ke ʻano he ana wela me ka nui o nā mea ʻike infrared, ʻoiaʻiʻo, he nui nā kuleana koʻikoʻi. A laila, e nānā pono kākou i ka mea ʻike infrared.
Hoʻolauna i nā mea ʻike maka infrared
ʻO kēlā me kēia mea ma luna o ka ʻole loa (-273°C) e hoʻopuka mau ana i ka ikehu infrared i loko o ke ākea a puni, no laila. A ʻo ka sensor infrared, hiki iā ia ke manaʻo i ka ikehu infrared o ka mea a hoʻololi iā ia i nā ʻāpana uila. Loaʻa ka sensor infrared i ka ʻōnaehana optical, ka ʻike ʻana i ka mea a me ke kaapuni hoʻololi.
Hiki ke hoʻokaʻawale ʻia ka ʻōnaehana Optical i ke ʻano hoʻouna a me ke ʻano noʻonoʻo e like me ke ʻano ʻokoʻa. Pono ka lawe ʻana i ʻelua ʻāpana, hoʻokahi e hoʻouna i ka infrared a me ka loaʻa ʻana o ka infrared. ʻO ka reflector, ma ka ʻaoʻao ʻē aʻe, pono hoʻokahi mea ʻike e hōʻiliʻili i ka ʻike i makemake ʻia.
Hiki ke hoʻokaʻawale ʻia ka mea ʻike i ka thermal detecting element a me ka photoelectric detecting element e like me ke kumu hana. ʻO Thermistors ka mea hoʻohana nui loa. Ke hoʻokau ʻia ka thermistor i ka radiation infrared, piʻi ka mahana, a hoʻololi ke kū'ē (ʻoi aku ka nui a i ʻole ka liʻiliʻi o kēia hoʻololi, no ka mea, hiki ke hoʻokaʻawale ʻia ka thermistor i loko o ka thermistor coefficient wela maikaʻi a me ka thermistor coefficient mahana maikaʻi ʻole), hiki ke hoʻololi ʻia i ka puka hōʻailona uila. ma o ke kaapuni hoololi. Hoʻohana pinepine ʻia nā mea ʻike kiʻi kiʻi e like me nā mea photosensitive, hana pinepine ʻia me ke alakaʻi sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium a me nā mea doped silicon.
E like me ka hoʻoili ʻana i nā hōʻailona like ʻole a me ka hoʻololi ʻana, hiki ke hoʻokaʻawale ʻia nā sensor infrared i ke ʻano analog a me ke ʻano kikohoʻe. ʻO ke kaʻapuni kaʻina hana hōʻailona o ka sensor pyroelectric infrared analog he tube-effect tube, ʻoiai ke kaʻapuni kaʻina hana hōʻailona o ka sensor infrared pyroelectric digital he chip digital.
Hoʻomaopopo ʻia nā hana he nui o ka sensor infrared ma o nā permutations like ʻole a me nā hui pū ʻana o ʻekolu mau mea koʻikoʻi: ʻōnaehana optical, element detection and conversion circuit. E nānā kākou i kekahi mau wahi ʻē aʻe kahi i hoʻololi ai nā mea ʻike infrared.
Hoʻohana ʻia i ka ʻenekona Infrared
1. ʻIke kinoea
Infrared optical kumu o ke kinoea sensor mea he ano e pili ana i kokoke infrared spectral koho absorption hiʻona o ka likeʻole kinoea molekele, ka hoʻohana 'ana i ke kinoea a me ka absorption ikaika pilina (Lambert - bila Lambert Beer kanawai) e ike a hoʻoholo i ka noonoo o ke kinoea mea kinoea. mea ʻike.
Hiki ke hoʻohana ʻia nā mea ʻike infrared no ka loaʻa ʻana o ka palapala ʻāina loiloi infrared e like me ka mea i hōʻike ʻia ma ke kiʻi ma luna. ʻO nā molekule i haku ʻia me nā ʻātoma like ʻole e hoʻopili i ka infrared absorption ma lalo o ka hoʻomālamalama ʻana o ke kukui infrared i ka alapine like, e hopena i nā loli i ka ikaika o ke kukui infrared. Wahi a nā piko nalu like ʻole, hiki ke hoʻoholo ʻia nā ʻano kinoea i loko o ka hui.
E like me ke kūlana o kahi kiʻekiʻe absorption infrared hoʻokahi, ʻo nā pūʻulu wale nō i loko o ka mole kinoea hiki ke hoʻoholo. No ka hoʻoholo pololei ʻana i ke ʻano o ke kinoea, pono mākou e nānā i nā kūlana o nā kiʻekiʻe absorption a pau ma waena o ka ʻāpana infrared o ke kinoea, ʻo ia hoʻi, ka infrared absorption fingerprint o ke kinoea. Me ka infrared spectrum, hiki ke nānā koke ʻia ka ʻike o kēlā me kēia kinoea i loko o ka hui.
Hoʻohana nui ʻia nā sensor kinoea infrared i ka petrochemical, ʻoihana metallurgical, ke ʻano hana mining, ka nānā ʻana i ka pollution ea a me ka ʻike e pili ana i ka carbon neutralization, ka mahiʻai a me nā ʻoihana ʻē aʻe. I kēia manawa, kūʻai nui nā lasers mid-infrared. Ke manaʻoʻiʻo nei au i ka wā e hiki mai ana, me ka nui o nā ʻoihana e hoʻohana ana i nā mea ʻike infrared e ʻike i ke kinoea, e lilo nā mea ʻike kino infrared i ʻoi aku ka maikaʻi a me ka maʻalahi.
2. Ana ka mamao infrared
Infrared ranging sensor he ʻano mea ʻike, ʻo ia ka hoʻohana ʻana i ka infrared e like me ke ʻano o ka ʻōnaehana ana, ākea ākea, manawa pane pōkole, hoʻohana nui ʻia i ka ʻepekema a me ka ʻenehana hou, ka pale aupuni a me nā māla a me nā mahiʻai.
Loaʻa iā Infrared Ranging Sensor i nā hōʻailona infrared e hoʻouna ana a loaʻa i nā diodes, me ka hoʻohana ʻana i ka sensor infrared ranging e hoʻokuʻu i kahi kukuna o ke kukui infrared, e hana ana i kahi kaʻina noʻonoʻo ma hope o ka hoʻomālamalama ʻana i ka mea, e noʻonoʻo ana i ka sensor ma hope o ka loaʻa ʻana o ka hōʻailona, a laila hoʻohana i ka CCD. ka hoʻoili kiʻi ʻana i ka lawe ʻana a me ka loaʻa ʻana o ka ʻikepili ʻokoʻa manawa. Hoʻopiliʻia ka mamao o ka mea ma hope o ka hanaʻana e ka mea hana hōʻailona. Hiki ke hoʻohana ʻia kēia ma nā ʻaoʻao kūlohelohe wale nō, akā ma nā panels reflective. ʻO ke ana ʻana i ka mamao, ka pane alapine kiʻekiʻe, kūpono no nā wahi ʻoihana paʻakikī.
3. Ka Infrared Transmission
Hoʻohana nui ʻia ka lawe ʻana i ka ʻikepili me ka hoʻohana ʻana i nā sensor infrared. Hoʻohana ka mana mamao TV i nā hōʻailona hoʻoili infrared e hoʻomalu mamao i ka TV; Hiki i nā kelepona paʻalima ke hoʻouna i ka ʻikepili ma o ka hoʻouna ʻana i ka infrared. He mau noi kēia i hoʻohana ʻia mai ka wā i hoʻomohala mua ʻia ai ka ʻenehana infrared.
4. Kiʻi Thermal Infrared
ʻO ke kiʻi kiʻi wela he mea ʻike passive hiki ke hopu i ka radiation infrared i hoʻopuka ʻia e nā mea āpau i ʻoi aku ka kiʻekiʻe o ka wela ma mua o ka ʻole. Ua hoʻokumu mua ʻia ka mea kiʻi thermal ma ke ʻano he mākaʻikaʻi koa a me ka ʻike maka pō, akā i ka lilo ʻana i mea hoʻohana nui ʻia, hāʻule ke kumukūʻai, no laila e hoʻonui nui ʻia ai ke kahua noi. ʻO nā noi kiʻi wela wela ka holoholona, ka mahiʻai, ka hale, ka ʻike kinoea, nā noi ʻoihana a me nā pūʻali koa, a me ka ʻike kanaka, ka nānā ʻana a me ka ʻike. I nā makahiki i hala iho nei, ua hoʻohana ʻia ke kiʻi wela infrared i nā wahi lehulehu e ana wikiwiki i ka mahana o nā huahana.
5. Infrared Induction
ʻO ka hoʻololi hoʻololi infrared kahi hoʻololi mana ma muli o ka ʻenehana infrared induction. Hoʻomaopopo ʻo ia i kāna hana mana ma ka ʻike ʻana i ka wela infrared i hoʻokuʻu ʻia mai ka honua waho. Hiki iā ia ke wehe koke i nā kukui, nā puka ʻakomi, nā ʻōleʻa anti-theft a me nā mea uila ʻē aʻe.
Ma o ka Fresnel lens o ka infrared sensor, hiki ke ʻike ʻia ke kukui infrared i hoʻopuehu ʻia e ke kino kanaka e ka hoʻololi, i ʻike ai i nā hana mana ʻokoʻa e like me ka hoʻohuli ʻana i ke kukui. I nā makahiki i hala iho nei, me ka kaulana o ka home akamai, ua hoʻohana ʻia ka infrared sensing i loko o nā pahu ʻōpala akamai, nā halepaku akamai, nā hoʻololi gesture akamai, nā puka induction a me nā huahana akamai ʻē aʻe. ʻAʻole pili ka ʻike infrared e pili ana i ka ʻike ʻana i nā kānaka, akā e hoʻonui mau ʻia e hoʻokō i nā hana hou aku.
Ka hopena
I nā makahiki i hala iho nei, ua ulu wikiwiki ka ʻoihana pūnaewele o nā mea a loaʻa i kahi mākeke ākea ākea. I kēia ʻōlelo, ua ulu hou ka mākeke sensor infrared. No laila, hoʻomau ka ulu ʻana o ka mākeke infrared detector market. Wahi a ka ʻikepili, ma 2019, ka nui o ka mākeke infrared detector Kina ma kahi o 400 miliona yuan, ma 2020 a i ʻole kokoke i 500 miliona yuan. Hoʻohui pū ʻia me ka noi no ke ana wela infrared o ka maʻi maʻi a me ka neutralization carbon no ka ʻike kinoea infrared, ʻoi aku ka nui o ka mākeke o nā sensor infrared i ka wā e hiki mai ana.
