Control Software
I-interface ye-Preci-Lock
Ukuze uthole isilawuli esingcono se-laser frequency, i-Preci-Lock ilahla amafindo aphathekayo nezinkinobho.Futhi zonke izinguquko zepharamitha nokulawulwa kokukhiya kutholwa yisoftware yePC.Isofthiwe ye-Preci-lock ihlanganisa imisebenzi yokulawula ukuxhumana, ireferensi nesibonisi sesignali yephutha, ukulungiswa kwamapharamitha wemojula ye-PID, ukulawula ukukhiya nokunye.Ngaphandle koxhumano oludingekayo ngokomzimba, isilawuli sokukhiya nge-laser singenziwa ngokugcwele ngesofthiwe ye-Preci Lock.Ukusebenza kwedijithali okumsulwa kulula kakhulu kumsebenzisi.Esinye isici sesofthiwe ye-Preci-Lock umsebenzi wokukhiya okuzenzakalelayo, okwazi ukubona ukukhiya okuzenzakalelayo kwe-laser frequency ngaphansi kwezilungiselelo zepharamitha ezinengqondo.Kumodi yokukhiya okuzenzakalelayo, i-Preci-Lock ingabona ukukhiya okuzenzakalelayo, ukuvula ukwahlulela nokukhiya kabusha imvamisa ye-laser.Le modi ingabona ukukhiya okuzinzile kwesikhathi eside kwefrikhwensi ye-laser, kulungele ikakhulukazi isilingo esibandayo se-athomu yefiziksi edinga ukulinganisa okuqhubekayo kwesikhathi eside.
Isibonelo
Njengemojula yokulawula ukukhiya esebenza ngokugcwele, i-Preci-Lock ingahlangabezana nezidingo eziningi zokukhiya imvamisa.I-frequency locking ingahlukaniswa ibe ukuguquguquka kwangaphakathi kanye nokukhiya ifrikhwensi yangaphandle yokushintshashintsha ngokuya ngokushintshashintsha okuhlukile.Izindlela ezimbili zokukhiya imvamisa zihlukile ngokomgomo kuyilapho ukuxhuma ngokomzimba kwe-Preci-Lock nakho kuhlukile kuzo.
I-spectrum yokumuncwa kwe-athomu ye-rubidium nesiginali yephutha ehambisanayo (kwesokunxele);
Imiphumela yokuqiniswa kwefrikhwensi yokushintshashintsha kwangaphakathi (kwesokudla).
◆Ukuzinzisa Imvamisa Yokuguquguquka Kwangaphakathi
Ukuze uthole ukushintshashintsha kwangaphakathi, isignali yokushintshashintsha kanye nempendulo ibonisa impendulo ndawonye ku-laser nge-adder.Iphoyinti lokukhiya imvamisa elihambisana nenani eliphakeme lamagagasi kanye ne-wave trough ye-spectra.Ukushintshashintsha okujwayelekile kokuqina kwangaphakathi kwefrikhwensi kwamukelwa ku-spectrum yokumuncwa kokugcwaliswa kwe-lock-in noma ukuqiniswa kwefrikhwensi yokumunca.
I-spectrum yokudlulisa i-athomu ye-rubidium kanye nesignali yephutha ehambisanayo (kwesokunxele);
Imiphumela yokuqiniswa kwefrikhwensi yokushintshashintsha kwangaphandle (kwesokudla).
◆Ukuzinzisa Imvamisa Yokuguquguquka Kwangaphandle
Ngokuguqulwa kwangaphandle, isignali yokuguquguquka kanye nesignali yempendulo kuyahlukaniswa futhi kwangaphandle
isignali yokushintshashintsha isetshenziswa kumodeli yangaphandle ezimele.Iphoyinti lokukhiya imvamisa elihambisana nephoyinti elinguziro le-spectra.Ukuguquguquka okujwayelekile kokuzinza kwefrikhwensi yangaphandle kwamukelwa ku-spectrum yokudluliswa kwe-modulation noma ukuzinzisa imvamisa ye-PDH.
