Mokhoa oa ho sebelisa fluorescent optical fiber ho lekanya molao-motheo oa mocheso

Molao-motheo oa Tekanyo ea Mocheso oa Bophelo ba Fluorescence

Ka mor'a ho khabisoa ke khanya, lielektrone tse linthong tse hlokolosi li monya fotone le ho fetoha ho tloha boemong bo tlase ba matla ho ea boemong bo thabileng bo phahameng ba matla, ebe o khutlela boemong bo tlaase ba matla ka ho fetola mahlaseli, ho ntša fluorescence. Phaello e tsitsitseng ea fluorescence ka mor'a hore lebone le hlasimollang le tlosoe ho itšetlehile ka nako ea bophelo ba naha e thabileng.. Hangata tlhahiso ena e senyeha ka sekhahla, mme nako e sa fetoheng ea ho bola ha exponential e ka sebelisoa ho lekanya bophelo bohle ba boemo ba thabo, se bitsoang nako ya ho bola ha fluorescence kapa nako ya ho bola ha fluorescence.

Fluorescence mocheso oa bophelo bohle oa sensor

Bolelele ba bophelo ba fluorescence bo itšetlehile ka mocheso. Lisensara tsa thempereichara ea bophelo bohle ba Fluorescence li ntša ponahalo e melang sebakeng se bonahalang ka mor'a hore lintho tse ling tse sa tloaelehang tsa lefatše li khantšitsoe le ho hlasimoloha ke khanya ea ultraviolet., ke hore, fluorescence le khanya ea eona e ka morao ke khanya ka mor'a hore thabo e khaotse. Haeba parameter ea fluorescence e fetotsoe ke mocheso 'me kamano e le monotonic, kamano ena e ka sebelisoa ho lekanya mocheso. Matla a mabone a marang-rang a amana le matla a mohloli oa leseli le tsosang maikutlo le mocheso oa thepa ea fluorescent.. Haeba mohloli oa leseli o lula o le teng, matla a fluorescent linear spectrum ke ts'ebetso e le 'ngoe ea boleng ba mocheso le ho senyeha ha nako e ntse e ea.. Ka kakaretso, e theola mocheso o kantle, matla a fluorescence mme a lieha ho bola. Ka ho sefa mahlaseli a hlasimollang ka sefe le ho lekanya botebo ba melapo e khanyang ea fluorescence afterglow emission spectral., mocheso o ka khethoa. Empa mokhoa ona oa ho lekanya o hloka matla a mabone a hlasimollang a tsitsitseng le kanale ea matšoao, eo ho leng thata ho fihlella, kahoo e sebelisoa ka seoelo. Holim'a moo, nako ea ho bola e sa fetoheng ea fluorescence afterglow hape ke ts'ebetso e le 'ngoe ea boleng ba mocheso.

Ho latela pono ea theory ea semiconductor, ho bola le ho nyamela ha khanya ke mokhoa oa ho tima khanya. Mocheso o phahameng, matla a ho sisinyeha ha letlapa, melumo e mengata e kenya letsoho ho monyeng, mme kganya e tima ka potlako. Ka hona, mocheso oa lisebelisoa tsa fluorescent o lekanya lebelo la ho tima leseli, ke hore, boholo ba nako ya ho bola bo sa fetoheng.

Monyetla o moholo oa ho sebelisa bophelo bohle ba fluorescence bakeng sa tekanyo ea mocheso ke hore kamano ea phetoho ea mocheso e khethoa ke nako ea bophelo ba fluorescence., 'me ha e angoe ke lintlha tse ling tsa kantle joalo ka liphetoho tsa matla a mohloli oa khanya ea excitation, katleho ea phetiso ea fiber, kapa degree ea coupling. Ka hona, e na le melemo e mengata ho feta mokhoa oa ho metha mocheso o sebelisa fluorescence peak intensity kapa intensity ratio e le lets'oao la ho lemoha mocheso., 'me e itšetlehile ka molao-motheo oa tekanyo ea mocheso oa fiber optic.

Sensor ea mocheso oa fiber optic, Mokhoa o bohlale oa ho beha leihlo, E ajoa ka moetsi oa fiber optic Chaena
