He aha te "tino kanapa"pūtake mārama"? E hia ōu mōhiotanga mō tēnei mea? Ko tāku tumanako ka taea e koe te tirotiro pai i ngā mōhiotanga moroiti hikohiko kua kawea mai ki a koe!"
Pūtake mārama tino hihi (e mōhiotia ana koPūtake mārama ASE) he pūtake mārama whānui (pūtake mārama mā) e ahu mai ana i te hihi nui rawa. (He maha ngā wā ka kiia he pūtake hihi nui rawa, e ahu mai ana i tētahi āhuatanga rerekē e kiia nei ko te hihi nui rawa.) I te nuinga o te wā, kei roto i tētahi pūtake mārama hihi nui rawa he reo whakanui taiaho e whiti ana i te mārama i muri i te whakaoho, kātahi ka whakanui ake hei tuku i te mārama.
He iti rawa te ōritetanga o te wā o ngā pūtake hihi-rahi nā te nui o te whānuitanga o te hihi (ki te whakaritea ki ngā hihi rēseri). Mā tēnei ka tino whakaitihia te tūponotanga o ngā ira mārama, e kitea pinepine ana i roto i ngā hihi rēseri. Heoi, he tino teitei tōna ōritetanga ā-wāhi, ā, ka taea te arotahi pai i te mārama putanga o te pūtake mārama hihi-rahi (he rite ki te hihi rēseri), nō reira he nui ake te kaha o te mārama i te kaha o te rama mura.
He tino pai tēnei mō te tirotiro i ngā pūtake mārama mārama (OpticalCoherenceTomography, OCT), te tātari āhuatanga o te taputapu () i roto i te whakawhitiwhiti muka whatu, te gyro me te pūoko muka whatu. Tirohia ngā diode superemitting mō ētahi atu whakamahinga taipitopito.
Ko tētahi o ngā pūtake mārama matua mō ngā diode irahiko ultra (Superluminescent DiodesRēhia SLD) me te whakakaha muka whatu. He nui ake te mana whakaputa o ngā pūtake mārama muka, he iti ake ia ngā SLD, ā, he iti ake te utu. He iti iho i te torutoru nanometer me te tekau nanometer te roa o te horapa o ngā irahiko o ia mea, ā, i ētahi wā he nui ake i te 100 nanometer.
Mō ngā pūtake mārama ASE whai-kaha katoa, me āta pehi te urupare whatu (hei tauira, te whakaata mai i ngā tauranga muka), kia puta ai he pānga taiaho pirinoa.ngā taputapu muka whatu, ka pā te mararatanga o Rayleigh i roto i te muka whatu ki te taupū mahi whakamutunga.
Pikitia 1: Ko te whānuitanga ASE i hangaia e te whakakaha muka ka tatauhia hei kōpiko i ngā mana papu rerekē. I te pikinga o te mana, ka neke te whānuitanga ki te roangaru poto ake (ka tere te piki o te whakanui) ā, ka whakawhāitihia te rārangi whānuitanga. He mea noa te nekehanga roangaru mō ngā pāpāho whakanui taumata-toru, engari ka puta te whakawhāiti rārangi i roto i te nuinga o ngā pūtake hihi-rahi.
