O le a le acousto-optic modulatorAOM modulator

Acousto-optic modulation o se metotia faʻaogaina fafo. E masani lava, o le masini acousto-optic e pulea le malosi o le fesuiaiga o le laser beam e taʻua o leacousto-optic modulator(AOM modulator). O le faʻailoga faʻaogaina e galue i luga o le eletise eletise eletise i le tulaga o se faʻailoga eletise (amplitude modulation), ona liua lea i totonu o se eletise ultrasonic e suia i foliga o se faʻailoga eletise. Pe a pasi atu galu malamalama i le acousto-optic medium, ona o le acousto-optic aafiaga, o le masini opitika e modulated ma avea ma se malosi modulated galu e "ave" faamatalaga.

Fa'avae galue

Acousto-optic modulationose faiga fa'aletino e fa'aogaina ai le acousto-optic effect e utaina ai fa'amatalaga i luga o se va'ava'a fa'avavevave. O le faʻailoga faʻaogaina e galue i luga o le eletise eletise eletise i le tulaga o se faʻailoga eletise (amplitude modulation), ona liua lea i totonu o se eletise ultrasonic e suia i foliga o se faʻailoga eletise. Pe a pasi atu galu malamalama i le acousto-optic medium, ona o le acousto-optic aafiaga, o le masini opitika e modulated ma avea ma se malosi modulated galu e "ave" faamatalaga.

O le acousto-optic modulator (AOM modulator) e masani ona faia i tioata acousto-optic, transducers, masini absorption ma avetaavale. O le faʻaogaina o faʻailoga faʻaalia mai le avetaʻavale e galue i luga o le transducer i foliga o se faʻailoga eletise ona liua lea i se galu ultrasonic e eseese i foliga o se faʻailoga eletise. Pe a pasi atu le galu ultrasonic i le acousto-optic medium, e mafua ai le faʻamalosi i le lotoifale ma le faʻalauteleina o le ala, faʻatupuina le faʻamalosi elastic. O lenei fa'afitauli e fesuisuia'i i lea taimi ma lea taimi i le taimi ma le avanoa, e mafua ai ona fa'aalia e le alalaupapa se fa'alavelave fa'afuase'i, e tutusa ma le fa'a'u'u vaega. A ui atu le malamalama i lenei ala faʻalavelave e galu ultrasonic, e tupu se faʻalavelave faʻafuaseʻi. O lenei fa'alavelave e ta'ua o le acousto-optic effect. I lalo o le aafiaga o le leo ma le malamalama, o le masini opitika e faʻapipiʻiina ma avea ma galu faʻasolosolo e "ave" faʻamatalaga.

Fa'a'ese'esega lelei ma fa'aletonu le fa'aogaina

2. Bragg Angle: Pe a fa'aofi le malamalama fa'alavelave i totonu o lemasini acousto-optici le Bragg Angle, e mafai ona ausia le lelei sili ona lelei. O mea sese angular o le a faʻaitiitia ai le lelei.

3. Divergence Angle fetuutuunai

4. Saosaoa suiga: O le taimi fesuiaʻi opitika e faʻamatalaina i le taimi faʻasalalau o le galu leo ​​e ala i le sulugatiti i le tioata A0.

5. Malosi'i RF Mana (Saturation Power)
