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

Tlhaloso

Acousto-optic effect experiment ke moloko o mocha oa liteko tsa 'mele Likholetjheng le liunivesithing, e sebelisetsoa ho ithuta tšebetso ea tšimo ea motlakase le tšebelisano ea tšimo e bobebe litekong tsa mantlha tsa fisiks le liteko tse amanang le tsona, hape e sebetsa ho patlisiso ea liteko ea optical. puisano le ts'ebetso ea tlhaiso-leseling. E ka bonts'oa ka pono ke oscilloscope ea dijithale habeli (O ka ikhethela).

Ha maqhubu a ultrasound a tsamaea ka seaplane, maqhubu a ka tlasa khatello ea elastic ka liphetoho tsa nako le nako le nako, a baka phetoho e ts'oanang ea nako le nako ho index ea refractive ea mahareng. Ka lebaka leo, ha lehlaseli la leseli le feta ka seiponeng ho le teng maqhubu a ultrasound a mahareng, le arohanngoa ke seaplane se sebetsang e le grating ea mohato. Ena ke khopolo ea mantlha ea phello ea acousto-optic.

Acousto-optic effect e arotsoe ka phello e tloaelehileng ea acousto-optic le phello e sa tloaelehang ea acousto-optic. Ka mokhoa oa isotropic, sefofane sa karohanyo ea leseli la ketsahalo ha se fetoloe ke tšebelisano ea acousto-optic (e bitsoang phello e tloaelehileng ea acousto-optic); ka sekhahla sa anisotropic, sefofane sa karohanyo ea leseli la ketsahalo se fetoloa ke tšebelisano ea acousto-optic (e bitsoang anomalous acousto-optic effect). Anomalous acousto-optic effect e fana ka motheo oa bohlokoa bakeng sa ho qaptjoa ha li-acousto-optic deflectors le li-filters tsa acousto-optic tse khonehang. Ho fapana le phello e tloaelehileng ea li-acousto-optic, phello e sa tloaelehang ea li-acousto-optic e ke ke ea hlalosoa ke Raman-Nath diffraction. Leha ho le joalo, ka ho sebelisa likhopolo tsa lipuisano tse kang ho ts'oana ha matla le ho se tsamaisane hantle le li-optics tse sa sebetseng, ho ka theoa khopolo e kopaneng ea tšebelisano ea acousto-optic ho hlalosa litlamorao tse tloaelehileng le tse sa khahliseng tsa acousto-optic. Liteko tsa sistimi ena li koahela phello e tloaelehileng ea li-acousto-optic mecheng ea litaba ea isotropic.
