Isoftware yokulawula
Ujongano lwe-Preci-Lock
Ukufumana ulawulo olungcono lwelaser, i-Preci-Lock iyawashiya amaqhosha omzimba kunye namaqhosha.Kwaye zonke iinguqu zeparameter kunye nolawulo lokutshixa zibonwa yisoftware yePC.I-software ye-Preci-lock iquka imisebenzi yokulawula unxibelelwano, ireferensi kunye nomboniso wesignali yephutha, ukulungiswa kweeparamitha zemodyuli ye-PID, ukulawula ukutshixa njalo njalo.Ngaphandle koqhagamshelo oluyimfuneko, ulawulo lokutshixa i-laser lunokuphunyezwa ngokupheleleyo nge-software ye-Preci Lock.Umsebenzi ococekileyo wedijithali ulungele ngakumbi kumsebenzisi.Olunye uphawu lwe-software ye-Preci-Lock ngumsebenzi wokutshixa ngokuzenzekelayo, onokuqonda ukutshixa ngokuzenzekelayo kwe-laser frequency phantsi koseto lweparameter efanelekileyo.Kwimowudi yokutshixa ngokuzenzekelayo, i-Preci-Lock inokuqonda ukutshixa ngokuzenzekelayo, ukuvula ukugweba kunye nokutshixa kwakhona i-laser frequency.Le mowudi inokuqonda ukutshixa kwexesha elide okuzinzileyo kwe-laser frequency, ngakumbi ilungele umfuniselo wefiziksi yeathom ebandayo efuna umlinganiselo wexesha elide oqhubekayo.
Umzekelo
Njengemodyuli esebenza ngokupheleleyo yolawulo lokutshixa, i-Preci-Lock inokuhlangabezana nezona mfuno zokutshixa rhoqo.Ukutshixa okuphindaphindiweyo kunokwahlulwa kube yimodyuli yangaphakathi kunye nokutshixa kwangaphandle kokumodareyitha ngokuhambelana nokumodareyitha okwahlukileyo.Iindlela ezimbini zokutshixa iifrikhwensi zahlukile ngokomgaqo ngelixa udibaniso lwasemzimbeni lwe-Preci-Lock lwahlukile kubo.

◆Uzinziso lokuModareyitha kwangaPhakathi rhoqo
Ukumodareyitha kwangaphakathi, isignali yokumodareyitha kunye nengxelo yengxelo yengxelo kunye ne-laser ngokusebenzisa i-adder.Indawo yokutshixa i-frequency ehambelana nencopho yamaza kunye ne-wave trough ye-spectra.Ukumodareyitha okuqhelekileyo kwangaphakathi kokuzinzisa kwamkelwe kwi-lock-in saturation yokufunxa i-spectrum okanye i-absorption spectrum frequency stabilization.

◆Uzinziso lwaNgaphandle lokuModyuli rhoqo
Ukumodareyitha kwangaphandle, isignali yokumodareyitha kunye nomqondiso wempendulo yahlulwe kwaye yangaphandle
uphawu lokumodareyitha lusetyenziswa kwimodyuli yangaphandle ezimeleyo.Indawo yokukhiya i-frequency ehambelana ne-zero point ye-spectra.Ukumodareyitha okuqhelekileyo kwangaphandle kozinzo kumkelwa kwi-modulation transfer spectrum okanye ukuzinziswa kwamaza ePDH.
