Yazisainkqubo ye-opticalukukhutshwa kunye nokwamkelwa kwe-laser

Inkqubo ye-laser emission and reception optical inamacandelo amabini amakhulu: i-emission optical module kunye ne-reception optical module. Iindawo zayo ezisetyenziswa kakhulu ziinkqubo ze-laser processing, iinkqubo zokufumanisa i-fluorescence kunye neenkqubo zokufumanisa i-Raman spectroscopy.

1. Imodyuli ye-emission optical inoxanduva olukhulu lokuhlanganisa, ukwandisa okanye ukubumba umqadi we-laser okhutshwa yi-laser, ukuze ikwazi ukukhutshwa ngeeparameter ezithile ezifana nomgangatho we-beam, i-divergence Angle kunye nokusasazwa kwamandla. Imodyuli ye-receiving optical isetyenziselwa ukuqokelela isignali ye-laser ebonakala ngasemva kwithagethi, ukwenza ukugxila, ukucoca kunye neminye imisebenzi kuyo, ukuze kube lula ukufumanisa kunye nokucubungula okulandelayo.

Iukukhutshwa nge-laserInkqubo iqulathe izinto ezibalulekileyo ezifana nomthombo wokukhanya okhutshwa yilaser, iqela lelensi eqokelelayo, isandisi semitha kunye nesakhi sokubumba. Njengomthombo wamandla wenkqubo yonke, iiparameter zokusebenza komthombo wokukhanya okhutshwa yilaser, ezifana nokuzinza kwe-wavelength kunye neempawu zokuphuma kwamandla, zimisela ngokuthe ngqo isiphumo sokucubungula okulandelayo kwe-optical. Iqela lelensi eqokelelayo, ngoyilo oluchanekileyo lwe-optical, licinezela i-Angle yokwahluka komqadi welaser ukuya kuluhlu oluncinci kakhulu, ukuqinisekisa ukuba ilaser igcina uxinzelelo lwamandla aphezulu ngexesha lokudluliselwa komgama omde. Isandisi semitha sikhulisa ububanzi bomqadi welaser ngokweemfuno zokwenyani ukuhlangabezana neemfuno zesicelo kwiimeko ezahlukeneyo. Into yokubumba ifikelela kulawulo oluguquguqukayo lwesimo somqadi welaser ngokutshintsha usasazo lwesigaba okanye usasazo lwe-amplitude yomqadi welaser, njengokuguqula umqadi weGaussian ube ngumqadi othe tyaba, ukuhlangabezana neemfuno zomgangatho womqadi kwiimeko ezithile zesicelo.

2. Iukwamkela nge-laserInkqubo iqulathe izinto eziphambili ezifana neqela leelensi ezifumanayo, izihluzi, kunye ne-photodetector. Iqela leelensi ezifumanayo linoxanduva lokuqokelela ngokufanelekileyo imiqondiso yelaser ebuthathaka eboniswa ngasemva ukusuka kwithagethi kwaye izijolise kumphezulu we-photodetector ngoyilo oluchanekileyo lwe-optical ukuphucula ukusebenza kakuhle kokwamkelwa kwesignali. Izihluzi zisetyenziselwa ukucoca ingxolo yangasemva kunye nezinye izibonakaliso zokukhanya eziphazamisayo, ukuqinisekisa ukuba kuphela imiqondiso yelaser yee-wavelengths ezithile ezinokufikelela kwi-detector, ngaloo ndlela ziphucula umlinganiselo wesignali-kwingxolo kunye nokuchaneka kokufumanisa kwenkqubo. Njengenxalenye yesiphelo senkqubo yokufumana i-laser, iiparameter zokusebenza zeisixhobo sokubona iifoto, njengobuntununtunu kunye nexesha lokuphendula, zimisela ngokuthe ngqo amandla okufumanisa inkqubo kunye nesantya sokucubungula imiqondiso yelaser.
