    Ke Kaʻina Hana o Thermopile Infrared Sensor - Thermoelectric Effect

    Thermoelectric Effect (Seebeck hopena)

    Inā ʻelua mau mea like ʻole a mau mea paha A a me B i loaʻa nā mea like me ke ʻano o ka hana ʻokoʻa, ke pili i ka hopena wela (Wahi Hoʻolaha Hot), wehe ʻia ma ke anu anuanu (Cold Junction Area), a me ka gradient mahana ma waena o ka wela. ka hopena a me ke anu anuanu ΔTHC, no laila ma ka hopena anuanu e hele ana kahi ikaika thermoelectromotive Vi waho.

    Ke hoʻoheheʻe ka radiation infrared waho i ka ʻāpana omo o ka mīkini ʻike, lawe ka ʻāpana omo i ka radiation infrared a hoʻolilo iā ia i ikehu wela. E hoʻomohala ʻia kahi gradient mahana i ka mahele e pili ana i ka wela a me ka wahi anuanu. Ma o ka Seebeck Effect o nā mea thermocouple, hiki ke hoʻohuli i ka gradient mahana i ka hoʻopuka hōʻailona uila.

    Thermoelectric Effect (Seebeck hopena)

    Kānana (ʻo ke ʻano o ka kānana IR he koho): koho i ka pā infrared, pale i nā nalu lōʻihi ʻē aʻe e hoʻopili i ka mea ʻike.

    Kāpena: ke kākoʻo mechanical o ke kānana IR

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

    Header: ke kākoʻo ʻenekini kākoʻo o ka ʻāpana

    Chip Thermistor (Koho): nānā i ke anuanu o kahi anuanu o ka pā TPS

    Mīkini kaʻapuni hana ASIC (pono ʻole, hoʻopuka hōʻailona hōʻailona): hoʻonohonoho i ka hōʻailona puka analog o ka chip TPS

    Hiki ke ʻike ʻia ke kumumanaʻo hana o ka puʻuwai sensor thermopile ʻo ia ka hoʻohuli kino pālua ʻana o ka "light-thermal-electric". Kahi mea ma luna o ka ʻole zero (me ke kino o ke kanaka) e hoʻomālamalama i nā kukuna infrared, inā koho i ka nalu lōʻihi kūpono ma o ka kānana infrared (5-14μm band window), ke hoʻopili ka mea infrared sensitive ma ka chip i ka wela infrared a huli i ke kukui i ka wela , i ka hopena o ka piʻi ʻana o ka mahana o ka ʻāpana omo, hoʻololi ʻia ka ʻokoʻa mahana ma waena o ka ʻāpana omo a me ka ʻāpana anuanu i loko o kahi mana uila ma o nā haneli o nā set of micro thermocouples series connection, a ʻike ʻia ka hōʻailona infrared ma hope o ka puka o ka uila hana ʻia.

    Ke ʻike nei mai ke kūkulu ʻana, ʻokoʻa ka mea ʻikepili infrared a Sunshine Technologies mai nā huahana maʻamau, "hollow out" kona ʻano. Aia kahi pilikia loea nui no kēia ʻano, ʻo ia hoʻi, pehea e waiho ai i kahi papa o 1μm kiʻi ʻoniʻoni paʻa ma kahi kahi o 1 mm wale nō.2, a e hōʻoia i ka hiki i ke kiʻi ʻoniʻoni ke lawa ka helu hoʻololi e hoʻololi ai i ke kukui infrared i loko o ka puka uila, i mea e hoʻokō ai i nā koi ikaika o ka sensor ʻO ia no ka mea ua lanakila ka Sunshine Technologies i kēia ʻenehana nui i hiki iā ia ke haki i ka monopoli lōʻihi o nā huahana haole i hoʻokahi hahau.
