Kedu ihe bụ ihe modulator acousto-optic?Ihe nhazi AOM

Nhazi Acousto-optic bụ usoro nhazi mpụta. N'ozuzu, ngwaọrụ acousto-optic nke na-achịkwa mgbanwe ike nke oghere laser a na-akpọihe modulator acousto-optic(AOM modulator). Mgbaàmà a gbanwere agbanwe na-arụ ọrụ na electroacoustic transducer n'ụdị mgbaàmà eletriki (modulation amplitude), a na-agbanwekwa ya ka ọ bụrụ ultrasonic field nke na-agbanwe n'ụdị mgbaàmà eletriki. Mgbe ebili mmiri ìhè gafere na acousto-optic media, n'ihi mmetụta acousto-optic, a na-agbanwe ihe na-ebu optical ma ghọọ ebili mmiri a na-agbanwe agbanwe nke na-ebu "ozi".
