Mawonekedwe a Preci-Lock
Kuti muwongolere bwino ma frequency a laser, Preci-Lock amasiya mabatani akuthupi ndi mabatani.Ndipo zosintha zonse za parameter ndikuwongolera kutseka zimazindikirika ndi pulogalamu ya PC.Pulogalamu ya Preci-Lock imaphatikizapo ntchito zowongolera kulumikizana, kuwunikira ndikuwonetsa chizindikiro cholakwa, kusintha magawo a module a PID, kuwongolera kutsekeka ndi zina zotero.Kupatula kulumikizidwa kofunikira, kuwongolera kwa laser kungathe kuzindikirika ndi pulogalamu ya Preci Lock.Kugwiritsa ntchito digito koyera ndikosavuta kwa ogwiritsa ntchito.Chinthu chinanso cha pulogalamu ya Preci-Lock ndi ntchito yotseka yokha, yomwe imatha kuzindikira kutsekeka kwa ma frequency a laser pansi pazikhazikiko zoyenera.Munjira yotsekera yokha, Preci-Lock imatha kuzindikira kutseka kwa auto, kumasula kuweruza ndikutsekanso ma frequency a laser.Njirayi imatha kuzindikira kutsekeka kosasunthika kwanthawi yayitali kwa ma frequency a laser, makamaka koyenera kuyesa kuzizira kwa fizikisi ya atomu komwe kumafunikira kuyeza kosalekeza kwa nthawi yayitali.
Chitsanzo
Monga gawo lowongolera lotsekera logwira ntchito mokwanira, Preci-Lock imatha kukwaniritsa zofunikira pakutseka pafupipafupi.Kutsekera pafupipafupi kumatha kugawidwa mukusintha kwamkati ndi kutsekeka kwakunja kwafupipafupi malinga ndi kusinthasintha kosiyana.Njira ziwiri zotsekera pafupipafupi ndizosiyana kwenikweni pomwe kulumikizana kwakuthupi kwa Preci-Lock kulinso kosiyana kwa iwo.
Rubidium atomu machulukitsidwe sipekitiramu ndi lolingana zolakwa chizindikiro (kumanzere);
Zotsatira zakukhazikika kwa ma frequency amkati (kumanja).
◆Kukhazikika Kwanthawi Zosintha Kwamkati
Pakusintha kwamkati, siginecha yosinthira ndi mayankho amawunikiza pamodzi ku laser kudzera mu adder.Frequency lock point yofananira ndi ma wave wave ndi ma wave trough ya spectra.Kukhazikika kwapakati pafupipafupi kukhazikika kumatengedwa mu lock-in saturation mayamwidwe sipekitiramu kapena mayamwidwe sipekitiramu pafupipafupi kukhazikika.
Rubidium atomu kusinthasintha kusintha sipekitiramu ndi lolingana zolakwa chizindikiro (kumanzere);
Zotsatira za kukhazikika kwa ma frequency akunja (kumanja).
◆Kukhazikika Kwanthawi Zosintha Kwakunja
Kwa kusintha kwakunja, chizindikiro chosinthira ndi chizindikiro cha mayankho amagawidwa ndi kunja
chizindikiro cha kusinthasintha chimagwiritsidwa ntchito ku modulator yakunja yodziyimira payokha.Ma frequency lock point omwe amafanana ndi zero point of the spectra.Kukhazikika kokhazikika kwakunja kwakunja kumatengera mawonekedwe osinthira kapena PDH frequency stabilization.
