Modulator ea acousto-optic ke engModulator ea AOM
Modulation ea acousto-optic ke mokhoa oa ho feto-fetoha ha molumo ka ntle. Ka kakaretso, sesebelisoa sa acousto-optic se laolang phapang ea matla a lebone la laser se bitsoamodulator ea acousto-optic(Modulator ea AOM). Letšoao le fetotsoeng le sebetsa ho transducer ea electroacoustic ka mokhoa oa lets'oao la motlakase (modulation ea amplitude), ebe le fetoloa tšimo ea ultrasonic e fetohang ka mokhoa oa lets'oao la motlakase. Ha maqhubu a khanya a feta ka har'a acousto-optic medium, ka lebaka la phello ea acousto-optic, mojari oa optic oa fetoloa 'me e ba leqhubu le fetotsoeng ka matla le "jarang" tlhahisoleseling.
Molao-motheo oa ho sebetsa
Ho feto-fetoha ha molumo oa acousto-opticke ts'ebetso ea 'mele e sebelisang phello ea acousto-optic ho kenya tlhahisoleseling ho mojari oa maqhubu a optical. Letšoao le fetotsoeng le sebetsa ho transducer ea electroacoustic ka mokhoa oa lets'oao la motlakase (modulation ea amplitude), ebe le fetoloa tšimo ea ultrasonic e fetohang ka mokhoa oa lets'oao la motlakase. Ha maqhubu a khanya a feta ka har'a acousto-optic medium, ka lebaka la phello ea acousto-optic, mojari oa mahlo oa fetoloa 'me e ba leqhubu le fetotsoeng ka matla le "jarang" tlhahisoleseling.
Modulator ea acousto-optic (modulator ea AOM) hangata e entsoe ka likristale tsa acousto-optic, li-transducer, lisebelisoa tsa ho monya le bakhanni. Tlhahiso ea lets'oao le fetotsoeng ho tsoa ho mokhanni e sebetsa ho transducer ka mokhoa oa lets'oao la motlakase ebe e fetoloa leqhubu la ultrasonic le fetohang ka mokhoa oa lets'oao la motlakase. Ha leqhubu la ultrasonic le feta ka har'a acousto-optic medium, le baka khatello ea lehae le ho hola ha medium, e hlahisang khatello ea elastic. Mofuta ona o fetoha nako le nako ka nako le sebaka, o etsa hore medium e bontše ketsahalo e fetohang ea density, e tšoanang le phase grating. Ha leseli le feta ka har'a medium ena e sitisoang ke maqhubu a ultrasound, ho hlaha ketsahalo ea diffraction. Ketsahalo ena e bitsoa phello ea acousto-optic. Tlas'a phello ea molumo le leseli, mojari oa optical oa fetoloa 'me e ba leqhubu le fetotsoeng le "jarang" tlhahisoleseling.
