He aha ka hana a ka mea ʻike kiʻi kiʻi?

Pehea ka mana o nā mea ʻike kiʻi kiʻi kiʻi i ko mākou honua ʻike ʻole ʻia

E noʻonoʻo paha pehea e hoʻoponopono ʻokoʻa ai kāu kelepona i ka ʻōlinolino, ʻike nā mīkini hale hana i nā huahana e lele ana, a i ʻole nā ​​pūnaewele palekana e ʻike i ke neʻe ʻana mai o kekahi? ʻO ka hero unsung ma hope o kēia mau hana, ʻo ia ka photoelectric detector - kahi mea e hoʻohuli ai i ke kukui i ʻike hana.

No laila, he ahaPololeiHana ʻia kahi mea ʻike Photoelectric?

Ma kona kumu, he photoelectric detector he mea ia ehoʻololi i nā hōʻailona māmā (photons) i nā hōʻailona uila (i kēia manawa a i ʻole ka uila). E noʻonoʻo e like me ka unuhi liʻiliʻi, ʻike i nā loli i ka mālamalama - inā ua ālai ʻia, ʻike ʻia, a i ʻole ka hoʻololi ʻana o ke kukui - a hoʻololi koke i kēlā ʻike i mea hoʻopuka uila e hiki ai i nā mīkini, kamepiula, a i ʻole nā ʻōnaehana hoʻomalu ke hoʻomaopopo a hana. ʻO kēia hiki ke kumu, ma muli o kahopena kiʻi uila(ma kahi e paʻi ai ka māmā i kekahi mau mea e hoʻokuʻu ai i nā electrons), hoʻolilo iā lākou i "mau maka" maʻalahi no nā noi lehulehu.

Pehea e hana maoli ai kēia mau "Mālama Sensors"?

ʻO ka hapa nui o nā mea ʻike photoelectric ʻekolu mau ʻāpana:

1. Ke Kumu Māmā (Emitter):ʻO ka maʻamau he LED (ʻulaʻula ʻike ʻia, ʻōmaʻomaʻo, a i ʻole infrared) a i ʻole kahi diode laser, e hoʻouna ana i kahi kukuna kukui.
2. ʻO ka mea loaʻa:ʻO ka maʻamau he photodiode a i ʻole phototransistor, i hoʻolālā pono ʻia e ʻike i ke kukui i hoʻokuʻu ʻia a hoʻololi i kona alo, ka ʻole, a i ʻole ka hoʻololi ʻana i ka ikaika i kahi au uila.
3. Ka Kaapuni ʻIke:ʻO ka lolo e hoʻoponopono i ka hōʻailona o ka mea hoʻokipa, kānana ʻana i ka walaʻau a hoʻoulu i kahi hoʻopuka maʻemaʻe a hilinaʻi (e like me ka hoʻohuli ʻana i ke kī a i ʻole ka hoʻouna ʻana i kahi hōʻailona ʻikepili).

ʻIke lākou i nā mea a i ʻole nā loli me ka hoʻohana ʻana i nā ʻano "ʻike" like ʻole:

• Ma o-Kua (Ka hoʻouna):Emitter a me ka mea hoʻokipa e kū ana kekahi i kekahi. ʻIke ʻia kahi mea i ka wāpolokake kukui kukui. Hāʻawi i ka laulā lōʻihi loa (10+ mika) a me ka hilinaʻi kiʻekiʻe.
• Hōʻike hou:Aia ka Emitter a me ka mea hoʻokipa i ka ʻāpana like, e kū pono ana i kahi reflector kūikawā. ʻIke ʻia kahi mea i ka wāhakiʻo ke kukui i ʻike ʻia. ʻOi aku ka maʻalahi o ka hoʻonohonoho ʻana ma mua o ka beam akā hiki ke hoʻopunipuni ʻia e nā mea ʻālohilohi loa.
• Hōʻike hoʻohālikelike:Aia ka Emitter a me ka mea hoʻokipa ma ka ʻāpana like, e kuhikuhi ana i ka pahu hopu. ʻIke ʻia ka mea i ka wānoonoo anahoʻi ka mālamalama i hoʻokuʻu ʻia i ka mea hoʻokipa. ʻAʻole pono i kahi mea hoʻokalakupua ʻokoʻa, akā pili ka ʻike ma ka ʻili o ka mea.
• Kāohi ʻana i ka hope (BGS):ʻO kahi ʻano diffuse akamai. Ke hoʻohana nei i ka triangulation, ʻo iawale nōʻike i nā mea i loko o kahi kikoʻī, ka mamao i hoʻonohonoho mua ʻia, me ka nānā ʻole i kekahi mea ma waho a i ʻole kokoke loa ma hope o ka pahu hopu.

No ke aha la lakou ma na wahi a pau? Nā Pōmaikaʻi Nui:

ʻO nā mea ʻike kiʻi kiʻi kiʻi e hoʻomalu i nā hana ʻike he nui no ka mea hāʻawi lākou i nā pono kūʻokoʻa:

• ʻIke Hoʻokaʻaʻole:ʻAʻole pono lākou e hoʻopā i ka mea, pale i ka ʻaʻahu a me ka waimaka ma luna o nā mea ʻike a me nā mea maʻalahi.
• Nā pae ʻike lōʻihi:ʻOi aku ka nui o nā ʻano ma waena o ka beam, ʻoi aku ka nui o nā mea ʻike inductive a i ʻole capacitive.
• Pane Uila-wikiwiki:Hoʻopili nā mea uila i nā microseconds, kūpono no nā laina hana kiʻekiʻe.
• Material Agnostic:ʻIke kokokekekahi mea- metala, plastik, aniani, lāʻau, wai, pahu pahu - ʻaʻole like me nā mea ʻike inductive e ʻike wale i ka metala.
• ʻIke Mea Liʻiliʻi & Hoʻoholo Kiʻekiʻe:Hiki ke ʻike i nā ʻāpana liʻiliʻi a i ʻole nā kūlana pololei.
• Hoʻokae kala a me ke ʻano like ʻole:Hiki ke hoʻokaʻawale i nā mea ma muli o ke ʻano o ka ʻike a i ʻole ke komo ʻana i nā lōʻihi hawewe māmā.

Ma hea ʻoe e ʻike ai iā lākou ma ka hana (Real-World Impact):

Nui nā noi a pili i nā ʻoihana āpau:

• ʻOihana ʻOihana (The Powerhouse):ʻO ka helu ʻana i nā huahana ma nā conveyors, hōʻoia i nā pāpale hue ma luna, ʻike i nā lepili, hoʻonoho i nā lima robotic, hōʻoia i ka piha ʻana o ka ʻeke, nānā i nā laina hui. He mea koʻikoʻi lākou i ka pono hana hana hou.
• Palekana a me ka mana komo:ʻO nā mea ʻike puka ʻakomi, nā kaola ʻike intrusion, nā ʻōnaehana helu kanaka.
• Mea Hoʻohana Electronics:ʻO nā mea ʻike kukui ambient smartphone, nā mea hoʻokele mamao TV, nā ʻiole ʻike.
• Kaʻa:ʻO nā mea ʻike ua no nā wipers maʻemaʻe, ʻike ʻia i nā ʻōnaehana palekana, ka mana o ke kukui.
• Papahana mālama ola kino:Nā mea koʻikoʻi inā mea ʻike uahike kālailai ʻana i nā laʻana ea ,nā oximeter puʻupuʻuke ana ʻana i ka oxygen koko, nā mea hana kiʻi lapaʻau e like me nā kiʻi CT kiʻekiʻe.
• Kūkākūkā:Ke hilinaʻi nei nā ʻupena fiber optic i nā photodetectors e hoʻohuli hou i nā pulu māmā i mau hōʻailona ʻikepili uila.
• ikehu:ʻO nā pūnaewele lā (he ʻano mea ʻike photovoltaic) e hoʻohuli ana i ka lā i uila.

He mālamalama ka wā e hiki mai ana: He aha ka mea aʻe?

ʻAʻole kū mālie ka ʻenehana ʻike kiʻi kiʻi. ʻO nā holomua ʻokiʻoki ke koi nei i nā palena:

• Hoʻonui liʻiliʻi loa:Ka hoʻomohala ʻana i nā mea ʻike liʻiliʻi liʻiliʻi me ka hoʻohana ʻana i nā nanomaterials like hybrid nanofibers a me nā nanowires silicon.
• Hoʻonui i ka hana:2D/3D heterostructure mau mea (e like me MoS2/GaAs, Graphene/Si) hiki i ka ultra-kiʻekiʻe-kiʻekiʻe, ultra-sensitive mea ike, a hiki no ka ho'āʻo UV kukui.
• ʻOi aku ka naʻauao:ʻO nā mea ʻike me ka nānā ʻana i ka spectral i kūkulu ʻia (hyperspectral imaging) a i ʻole ka naʻau polarization no ka hopu ʻana i ka ʻike waiwai.
• Nā noi ākea:E ʻae i nā mea hou i nā diagnostics lapaʻau, ka nānā ʻana i ke kaiapuni, quantum computing, a me nā hōʻike o ka hanauna e hiki mai ana.

Makeke Boom: E noʻonoʻo ana i ka makemake

ʻO ka ulu ʻana o ka pahū i ka automation a me nā ʻenehana akamai e hoʻoulu pololei i ka mākeke detector photoelectric. Waiwai maʻO $ 1.69 biliona ma 2022, ua manaʻo ʻia e piʻi a hiki i kahi hoʻohiwahiwaʻO $ 4.47 biliona e 2032, e ulu ana ma kahi 10.2% CAGR ikaika.. ʻO kaʻĀpana ʻĀsia-Pākīpika, alakaʻi ʻia e ka mīkini hana nui a me ka hana uila, ke alakaʻi nei i kēia uku. Ke hoʻomau nei nā mea pāʻani nui e like me Hamamatsu, OSRAM, a me LiteON e hoʻokō i kēia koi piʻi nui.
