Pūnaehana kumu kukui makai lehulehu
ʻO ke kumu kumu a me ke kumu o ke kumu kukui multi-band
ʻO kahi kumu kukui multi-band he ʻōnaehana ʻōpika e hoʻokaʻawale i ke kukui keʻokeʻo i hoʻokuʻu ʻia e ke kumu kukui i loko o nā pūʻulu like ʻole e hoʻokahi a ʻelua paha pūʻulu o nā kānana kala, a laila e hoʻopuka iā ia ma o kahi alakaʻi māmā.He ʻelima mau ʻāpana: kumu kukui, ʻōnaehana kānana, ʻōnaehana hoʻopuka, ʻōnaehana hōʻike mana, a me ke Kuhina.(E nānā i ke Kiʻi 1 no ka hale).I waena o lākou, ʻo ke kumu kukui, ka ʻōnaehana kānana, a me ka ʻōnaehana hoʻopuka nā ʻāpana kumu o ke kumu kukui multi-band, e hoʻoholo ai i ka hana o ke kumu kukui.Hoʻohana maʻamau ke kumu kukui i ke kukui xenon, indium light a i ʻole nā kukui halide metala ʻē aʻe me ka hana kukui kiʻekiʻe.ʻO ka ʻōnaehana kānana e pili nui ana i ka kānana kala, aia nā kānana kala i uhi ʻia a i ʻole nā kānana kala hoʻopili band-pass kiʻekiʻe.ʻOi aku ka maikaʻi o ka hana o ka mea hope ma mua o ka mea mua, ka mea e hoʻemi nui i ka bandwidth ʻoki ʻia o ke kukui kala, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka monochromaticity o ke kukui kala.ʻO 350 ~ 1000nm ka lōʻihi o ka hawewe puka maʻamau, me ka hapa nui o nā laina spectral i ka ultraviolet hawewe lōʻihi, ʻike ʻia a me nā wahi kokoke-infrared.
Hoʻohana kumu o ke kumu kukui multi-band
1. ʻO ka fluorescence a me nā kumu kukui multi-band
Ke hauʻoli nā electron extranuclear a lele i ke kūlana hauʻoli, ʻaʻole paʻa nā electrons i ka moku hauʻoli a lele mau i ka ʻāina me ka ikaika haʻahaʻa.I ka wā o ka lele ʻana, e hoʻokuʻu ʻia ka ikehu i loaʻa ma ke ʻano o nā photons..ʻO ke ʻano o ka hauʻoli o kahi mea i kahi kūlana hauʻoli ma hope o ka hoʻomālamalama ʻia ʻana e kahi photon o kekahi lōʻihi hawewe, a laila lele hou i kahi pae ikehu haʻahaʻa ma o ka hoʻokuʻu ʻana i kahi photon o kekahi lōʻihi hawewe kikoʻī.
Ua kapa ʻia ʻo photoluminescence phenomenon, a ʻo ke ola photon maʻamau i hoʻokuʻu ʻia ma lalo o 0.000001 kekona, i kapa ʻia ʻo fluorescence;ma waena o 0.0001 a me 0.1 kekona, ua kapa ʻia ʻo phosphorescence.Inā hiki i kahi mea ke hoʻoulu a hoʻohua i ka fluorescence me ka ʻole o ka hoʻoulu ʻana o ka māmā o waho, ua ʻōlelo ʻia he fluorescence intrinsic ka mea.ʻO kekahi kūlana o ka fluorescence, ʻo ia ka hoʻoulu ʻana i nā nalu māmā me nā nalu ʻokoʻa mai nā nalu māmā mua (maʻamau ka hoʻoulu ʻana o ka nalu pōkole e hoʻohua i nā nalu lōʻihi) ma lalo o ka hoʻoulu ʻana o kahi kumu kukui waho, a ʻo ka hōʻike macroscopic e hoʻopuka i kahi kukui kala ʻē aʻe.ʻAʻole hiki i ke kumu kukui multi-band ke hāʻawi i kahi kumu kukui inverse no ka nānā ʻana i ka fluorescence intrinsic, akā he kumu kukui hoʻoulu.
2. Kumu hoʻokaʻawale kala
ʻO ke kumu o ka hoʻokaʻawale kala ka mea e pono ai no ke koho pololei ʻana i ka pūʻulu nalu (light light) a me ka kānana kala o ke kumu kukui multi-band.ʻo ia hoʻi ma ke koho ʻana i nā malu.
