Ngenisauhlelo lwe-opticalukukhishwa kwe-laser kanye nokwamukelwa
Uhlelo lwe-laser emission and reception optical luqukethe izingxenye ezimbili ezinkulu: i-emission optical module kanye ne-reception optical module. Izinkambu zalo ezisetshenziswa kakhulu yizinhlelo zokucubungula i-laser, izinhlelo zokuthola i-fluorescence kanye nezinhlelo zokuthola i-Raman spectroscopy.
1. Imojula ye-optical yokukhipha umoya inesibopho esikhulu sokuqoqa, ukwandisa noma ukwakha umsebe we-laser okhishwa yi-laser, ukuze ukhishwe ngamapharamitha athile njengekhwalithi yomsebe, i-Angle yokwehlukana kanye nokusatshalaliswa kwamandla. Imojula ye-optical yokwamukela isetshenziselwa ukuqoqa isignali ye-laser eboniswa emuva kusuka ekuqondisweni, ukwenza ukugxila, ukuhlunga kanye neminye imisebenzi kuyo, ukuze kube lula ukuthola nokucubungula okulandelayo.
Iukukhishwa kwe-laseruhlelo luqukethe izingxenye ezibalulekile njengomthombo wokukhanya okukhipha i-laser, iqembu lelensi elihlanganisayo, isandisi se-beam kanye nesici sokubumba. Njengomthombo wamandla wesistimu yonke, amapharamitha okusebenza komthombo wokukhanya okukhipha i-laser, njengokuqina kwe-wavelength kanye nezici zokukhipha amandla, anquma ngqo umphumela wokucubungula okulandelayo kwe-optical. Iqembu lelensi elihlanganisayo, ngokuklama okunembile kwe-optical, licindezela i-engela yokwehluka komsebe we-laser ibe ububanzi obuncane kakhulu, okuqinisekisa ukuthi i-laser igcina ukuhlushwa kwamandla aphezulu ngesikhathi sokudlulisa ibanga elide. Isandisi se-beam sikhulisa ububanzi bomsebe we-laser ngokwezidingo zangempela ukuze kuhlangatshezwane nezidingo zohlelo lokusebenza ezimweni ezahlukene. Isici sokubumba sifinyelela ukulawula okuguquguqukayo kwesimo somsebe we-laser ngokushintsha ukusatshalaliswa kwesigaba noma ukusatshalaliswa kwe-amplitude komsebe we-laser, njengokuguqula umsebe we-Gaussian ube umsebe oyisicaba, ukuze kuhlangatshezwane nezidingo zekhwalithi yomsebe ezimweni ezithile zohlelo lokusebenza.
2. Iukwamukela nge-laseruhlelo luqukethe izingxenye eziyinhloko njengeqembu lelensi elamukelayo, izihlungi, kanye ne-photodetector. Iqembu lelensi elamukelayo linesibopho sokuqoqa ngempumelelo izimpawu ze-laser ezibuthakathaka ezibonakala emuva kusuka ekuhlosweni bese zigxila ebusweni be-photodetector ngomklamo oqondile wokukhanya ukuze kuthuthukiswe ukusebenza kahle kokwamukela izimpawu. Izihlungi zisetshenziselwa ukuhlunga umsindo wangemuva kanye nezinye izimpawu zokukhanya eziphazamisayo, ukuqinisekisa ukuthi izimpawu ze-laser kuphela zamaza athile zingafinyelela kumtholi, ngaleyo ndlela kuthuthukiswe isilinganiso sesignali kuya kumsindo kanye nokunemba kokuthola uhlelo. Njengengxenye yokugcina yesistimu yokwamukela i-laser, amapharamitha okusebenza eumshini wokuthola izithombe, njengokuzwela nesikhathi sokuphendula, kunquma ngqo ikhono lohlelo lokuthola kanye nesivinini sokucubungula amasignali e-laser.
