Kodi acousto-optic modulator ndi chiyaniAOM module

Acousto-optic modulation ndi njira yakunja yosinthira. Nthawi zambiri, chipangizo cha acousto-optic chomwe chimayang'anira kusiyanasiyana kwa mtengo wa laser chimatchedwaacousto-optic modulator(AOM modulator). Chizindikiro chosinthidwa chimagwira ntchito pa electroacoustic transducer ngati chizindikiro cha magetsi (amplitude modulation), ndiyeno imasinthidwa kukhala gawo la akupanga lomwe limasintha ngati chizindikiro chamagetsi. Pamene mafunde a kuwala amadutsa mu acousto-optic sing'anga, chifukwa cha mphamvu ya acousto-optic, chonyamuliracho chimasinthidwa ndikukhala mphamvu yosinthika yomwe "imanyamula" chidziwitso.

Mfundo yogwira ntchito

Acousto-optic modulationndi njira yakuthupi yomwe imagwiritsa ntchito mphamvu ya acousto-optic kutsitsa zambiri pa chonyamulira cha pafupipafupi. Chizindikiro chosinthidwa chimagwira ntchito pa electroacoustic transducer ngati chizindikiro cha magetsi (amplitude modulation), ndiyeno imasinthidwa kukhala gawo la akupanga lomwe limasintha ngati chizindikiro chamagetsi. Pamene mafunde a kuwala amadutsa mu acousto-optic sing'anga, chifukwa cha mphamvu ya acousto-optic, chonyamuliracho chimasinthidwa ndikukhala mphamvu yosinthika yomwe "imanyamula" chidziwitso.

Acousto-optic modulator (AOM modulator) nthawi zambiri imakhala ndi ma acousto-optic crystals, transducers, zida zoyamwitsa ndi madalaivala. Kutulutsa kwa chizindikiro chosinthika kuchokera kwa dalaivala kumagwira ntchito pa transducer ngati chizindikiro chamagetsi ndipo kenako kumasinthidwa kukhala mafunde a ultrasonic omwe amasiyana ndi mawonekedwe amagetsi. Pamene akupanga yoweyula akudutsa acousto-mawonekedwe sing'anga, zimayambitsa m'deralo psinjika ndi elongation wa sing'anga, kupanga zotanuka kupsyinjika. Izi zimasintha nthawi ndi nthawi ndi nthawi ndi malo, zomwe zimapangitsa kuti sing'angayo iwonetsere kachulukidwe kosinthika, kofanana ndi grating ya gawo. Kuwala kukadutsa mu sing'anga iyi kusokonezedwa ndi mafunde akupanga, chodabwitsa cha diffraction chimachitika. Chodabwitsa ichi chimatchedwa acousto-optic effect. Pansi pa mphamvu ya phokoso ndi kuwala, chonyamulira cha kuwala chimasinthidwa ndikukhala mafunde osinthika omwe "amanyamula" chidziwitso.

Kuchita bwino kwa diffraction ndi kutayika kwa kusintha

2. Bragg Angle: Pamene kuwala kwa chochitika kulowetsedwa muchipangizo cha acousto-opticpa Bragg Angle, njira yabwino kwambiri yosinthira imatha kupezeka. Zolakwa za angular zidzachepetsa mphamvu.

3. Divergence Angle kusintha

4. Kuthamanga kwachangu: Nthawi yosinthira kuwala imatanthauzidwa ndi nthawi yotumizira phokoso la phokoso kudzera m'chiuno chamtengo mu kristalo ya A0.
