Sistimi ea Teko ea LPT-2 bakeng sa Phello ea Acousto-Optic

Tlhaloso e Khutšoanyane:

Teko ea Acousto-optic effect ke moloko o mocha oa lisebelisoa tsa liteko tsa 'mele Likholetjheng le liunivesithing, e sebelisetsoa ho ithuta ts'ebetso ea tlhaho ea lebala la motlakase le tšebelisano ea lebala le bobebe litekong tsa mantlha tsa fisiks le liteko tse amanang le tsona, hape e sebetsa le lipatlisisong tsa liteko tsa optical. puisano le ts'ebetso ea tlhahisoleseling ea optical.E ka bonts'oa ka pono ka oscilloscope ea dijithale e habeli (Ka boikhethelo).

Ha maqhubu a ultrasound a tsamaea ka mokhoa o itekanetseng, bohareng bo tlas'a khatello ea elastic le liphetoho nako le nako ka nako le sebaka, ho baka phetoho e tšoanang ea nako le nako ho index ea refractive ea medium.Ka lebaka leo, ha lehlaseli la leseli le feta ka har'a seaplane ka pel'a maqhubu a ultrasound bohareng, le fapane le seaplane se sebetsang e le grating ea mohato.Ena ke mohopolo oa mantlha oa phello ea acousto-optic.

Acousto-optic effect e arotsoe ka phello e tloaelehileng ea acousto-optic le phello e makatsang ea acousto-optic.Sebakeng sa isotropic, sefofane sa polarization ea leseli la ketsahalo ha se fetoloe ke ho sebelisana ha acousto-optic (e bitsoang normal acousto-optic effect);sebakeng sa anisotropic, sefofane sa polarization ea leseli la ketsahalo se fetoloa ke ho sebelisana ha acousto-optic (e bitsoang anomalous acousto-optic effect).Phello e sa tloaelehang ea acousto-optic e fana ka motheo oa bohlokoa bakeng sa ho etsoa ha li-deflector tse tsoetseng pele tsa acousto-optic le li-filters tsa acousto-optic tse tunable.Ho fapana le phello e tloaelehileng ea acousto-optic, phello e makatsang ea acousto-optic e ke ke ea hlalosoa ke Raman-Nath diffraction.Leha ho le joalo, ka ho sebelisa mehopolo ea tšebelisano ea parametric joalo ka ho bapisa lebelo le ho nyallana ho li-nonlinear optics, ho ka theoa khopolo e kopaneng ea tšebelisano ea acousto-optic ho hlalosa litlamorao tse tloaelehileng le tse makatsang tsa acousto-optic.Liteko tsa sistimi ena li akaretsa feela phello e tloaelehileng ea acousto-optic mecheng ea litaba ea isotropic.
