Inkqubo yovavanyo ye-LPT-2 yesiphumo se-Acousto-Optic

Inkcazo

Uvavanyo lwempembelelo ye-Acousto-optic sisizukulwana esitsha sezixhobo zokulinga kwiikholeji nakwiiyunivesithi, isetyenziselwa ukufunda inkqubo ebonakalayo yentsimi yombane kunye nokukhanya kwentsimi yokuhlangana kulingo olusisiseko lwefiziki kunye nolingo olunxulumene nobuchwephesha, kwaye ikwasebenza kuphando lovavanyo lwamehlo unxibelelwano kunye nokulungiswa kwengcaciso. Ingabonakaliswa ngokubonakalayo nge-oscilloscope yedijithali ephindwe kabini (Ngokuzithandela).

Xa amaza e-ultrasound ahamba phakathi, indawo leyo iphantsi koxinzelelo lwe-elastic kunye notshintsho olwenzeka ngamaxesha nakwisithuba, kubangela utshintsho olufanayo kumaxesha ngamaxesha kwisalathiso sokuphinda siphakathi. Ngenxa yoko, xa ukukhanya kokukhanya kugqitha phakathi kobukho bamaza e-ultrasound phakathi, iyaphazanyiswa kukusebenza okuphakathi njengesigaba sothango. Le yithiyori esisiseko yesiphumo se-acousto-optic.

Umphumo we-Acousto-optic uhlelwe kwisiphumo esiqhelekileyo se-acousto-optic kunye nefuthe le-acousto-optic. Kwi-isotropic medium, inqwelomoya yokuqaqanjelwa kokukhanya kwesiganeko ayitshintshwanga kukunxibelelana kwe-acousto-optic (ebizwa ngokuba yimpembelelo ye-acousto-optic); kwindawo ye-anisotropic, inqwelomoya yokukhanya kwesiganeko itshintshiwe kukunxibelelana kwe-acousto-optic (ebizwa ngokuba sisiphumo se-acousto-optic). Impembelelo ye-acousto-optic ye-Anomalous ibonelela ngesiseko esiphambili sokuyilwa kwe-acousto-optic deflectors kunye neefilitha ze-acousto-optic. Ngokungafaniyo nefuthe eliqhelekileyo le-acousto-optic, isiphumo esingathandekiyo se-acousto-optic asinakuchazwa ngu-Raman-Nath diffraction. Nangona kunjalo, ngokusebenzisa iikhonsepthi zokunxibelelana kweparametric njengokufana komfutho kunye nokungahambelani ngokukhanya okungahambelaniyo nomgaqo, inokumiselwa ithiyori emanyeneyo yokunxibelelana kwe-acousto-optic yokuchaza iziphumo eziqhelekileyo kunye nezithandekayo ze-acousto-optic. Uvavanyo kule nkqubo lugubungela kuphela isiphumo se-acousto-optic kwimithombo yeendaba ze-isotropic.

Uvavanyo lweMizekelo 

1. Jonga uBragg diffraction kunye nomlinganiso weBragg diffraction angle

2. Bonisa i-acousto-optic modulation waveform

3. Qaphela i-acousto-optic deflection phenomenon

4. Linganisa ukusebenza kakuhle kwe-acousto-optic kunye ne-bandwidth

5. Linganisa isantya sokuhamba kwamaza e-ultrasound phakathi

6. Linganisa unxibelelwano lokukhanya usebenzisa ubuchule bokumodareyitha be-acousto-optic
