Njira Yoyesera ya LPT-2 ya Zotsatira za Acousto-Optic

Kufotokozera

Kuyesera kwa Acousto-optic ndimibadwo yatsopano yazida zamagetsi ku Makoleji ndi mayunivesite, imagwiritsidwa ntchito kuphunzira momwe magwiridwe antchito amagetsi ndimayendedwe am'mayendedwe oyeserera poyeserera koyambirira kwa sayansi ndi zoyeserera zogwirizana, komanso imagwiranso ntchito pakufufuza koyesa kwa mawonekedwe kulumikizana ndi mawonekedwe azamagetsi. Ikhoza kuwonetsedwa mwazithunzi ndi oscilloscope ya digito (ngati mukufuna).

Mafunde a ultrasound akamayenda mwa sing'anga, sing'angayo imatha kupanikizika ndikusintha kwakanthawi ndi nthawi, ndikupangitsa kusintha kwakanthawi kofananako mu index ya refractive ya sing'anga. Zotsatira zake, pamene kuwala kwa kuwala kumadutsa sing'anga pamaso pa mafunde a ultrasound pakatikati, imasokonezeka ndi sing'anga yomwe imakhala ngati grating. Ichi ndiye chiphunzitso choyambirira cha mphamvu ya acousto-optic.

Mphamvu ya Acousto-optic imagawidwa mwanjira yodziwika bwino yamagetsi ndi zoyipa zamphamvu zamayimbidwe. Pakatikatikatikati mwa isotropic, kuwuluka kwa kuwunikaku sikusinthidwa ndimayendedwe acousto-optic (otchedwa acousto-optic effect); mu sing'anga ya anisotropic, kuwongolera kwa kuwalako kwa chochitikacho kumasinthidwa ndi kulumikizana kwa acousto-optic (kotchedwa anomalous acousto-optic effect). Anomalous acousto-optic effect imapereka maziko ofunikira opangira ma acousto-optic deflectors ndi zosefera za acousto-optic. Mosiyana ndi magwiridwe antchito acousto-optic, zovuta za acousto-optic sizingathe kufotokozedwa ndi Raman-Nath diffraction. Komabe, pogwiritsa ntchito malingaliro olumikizana ndi ma parametric monga kufulumira kwamphamvu ndi kusalongosoka kwa ma optics osagwirizana, lingaliro logwirizana la kulumikizana kwa acousto-optic lingakhazikitsidwe kuti lifotokozere zonse zachilendo komanso zosasangalatsa za acousto-optic. Kuyesera m'dongosolo lino kumangotenga mawonekedwe acousto-optic mu media isotropic.

Yesani Zitsanzo 

1. Onetsetsani kupindika kwa Bragg ndikuyesa ngodya ya Bragg

2. Onetsani mawonekedwe a acousto-optic modulation wave

3. Onaninso chodabwitsa cha acousto-optic deflection

4. Kuyeza acousto-chamawonedwe mapindidwe akuwala ndi bandiwifi

5. Kuyeza mathamangidwe a mafunde a ultrasound mu sing'anga

6.Yesetsani kulumikizana kwamawonekedwe pogwiritsa ntchito njira yamagetsi yamagetsi yamagetsi
