Ke Kumu Hana o Thermopile Infrared Sensor - Thermoelectric Effect

Ka hopena Thermoelectric(Seebeck Effect)

Inā ʻelua mau mea ʻokoʻa a i ʻole nā mea ʻokoʻa A a me B i loaʻa nā mea like ʻoiai me ka hana hana ʻokoʻa, ke hoʻopili ʻia ma ka wela wela (Hot Junction Area), wehe ʻia ma ka hopena anu (Cold Junction Area), a me ka gradient wela ma waena o ka wela. ʻO ka hopena a me ka hopena anu he ΔT_HC, no laila, ma ka hopena anu, e loa'a ana ka ikaika thermoelectromotive V_{i waho}.

I ka wā e hoʻomālamalama ai ka pāhawewe infrared o waho i ka wahi absorption o ka mea ʻike, hoʻopau ka absorption zone i ka pāhawewe infrared a hoʻololi i ka ikehu wela.E hana ʻia kahi ʻanuʻu wela ma kahi hui wela a me kahi hui anu.Ma o ka Seebeck Effect o ka thermocouple material, hiki ke hoʻololi ʻia ka gradient wela i ka puka hōʻailona uila.

Kānana(ʻO ke ʻano o ka kānana IR he koho): koho i ka pūʻulu infrared, e pale i ka lōʻihi hawewe ʻē aʻe o ka mālamalama e hoʻopilikia i ka mea ʻike.

Kāpena: ke kākoʻo mechanical structure o IR kānana.

TPS Chip: e ʻike i ka hōʻailona infrared e hele ana ma ka kānana IR.

Poʻomanaʻo: ke kākoʻo ʻana i ke ʻano mechanical o chip.

ʻO ka ʻaumaha puʻupuʻu(Koho): E nānā i ka wela o ka wahi hui anu o TPS chip.

chip kaapuni hana ASIC(ke koho, ka hoʻopili ʻana i ka hōʻailona hōʻailona): hoʻopololei i ka hōʻailona hoʻopuka analog o TPS chip.

Hiki ke ʻike ʻia ʻo ke kumu hana o ka thermopile sensor chip ʻo ia ka hoʻololi kino ʻelua o ka "light-thermal-electricity".ʻO kēlā me kēia mea ma luna o ka zero loa (me ke kino o ke kanaka) e hoʻopuka i nā kukuna infrared, inā koho i ka lōʻihi hawewe kūpono ma o ka kānana infrared (5-14μm band window), i ka wā e komo ai ka infrared sensitive material ma ka chip i ka wela infrared a hoʻohuli i ke kukui i wela. ʻO ka hopena o ka piʻi ʻana o ka wela o ka ʻāpana absorption, ua hoʻololi ʻia ka ʻokoʻa wela ma waena o ka absorption zone a me ka junction junction zone i kahi puka uila ma o nā haneli o nā pūʻulu micro thermocouples series connector, a ʻike ʻia ka hōʻailona infrared ma hope o ka puka ʻana o ka uila. hanaia.

I ka ʻike ʻana mai ka hale, ʻokoʻa ka sensor infrared thermopile a Sunshine Technologies mai nā huahana maʻamau, ʻo kona ʻano he "hollow out".Aia kekahi pilikia ʻenehana koʻikoʻi no kēia hale, ʻo ia hoʻi, pehea e kau ai i kahi papa o 1μm mānoanoa hoʻokuʻu kiʻi ʻoniʻoni ma kahi o 1 mm wale nō.², a e hōʻoia i hiki i ke kiʻiʻoniʻoni ke loaʻa i ka nui o ka hoʻololi ʻana e hoʻohuli i ke kukui infrared i ka hoʻopuka hōʻailona uila, i mea e hoʻokō ai i nā koi ikaika hōʻailona o ka ʻike.No ka mea, ua lanakila ʻo Sunshine Technologies i kēia ʻenehana koʻikoʻi e hiki ai iā ia ke wāwahi i ka monopoly lōʻihi o nā huahana haole i hoʻokahi hahau.
