Chii chinonzi acousto-optic modulatormodulator yeAOM
Kuchinja kweAcousto-optic inzira yekushandura kwekunze. Kazhinji, mudziyo weacousto-optic unodzora kusiyana kwesimba remwaranzi welaser unonzimodulator yeacousto-optic(AOM modulator). Chiratidzo chakagadziriswa chinoshanda pa electroacoustic transducer muchimiro chechiratidzo chemagetsi (amplitude modulation), uye chinozoshandurwa kuita munda we ultrasonic unoshanduka muchimiro chechiratidzo chemagetsi. Kana mafungu echiedza apfuura nepakati pe acousto-optic medium, nekuda kwe acousto-optic effect, optical carrier inogadziriswa uye inova intensity modulated wave "inotakura" ruzivo.
Musimboti wekushanda
Kuchinja kweAcousto-opticinzira yepanyama inoshandisa acousto-optic effect kuisa ruzivo pa optical frequency carrier. Chiratidzo chakagadziriswa chinoshanda pa electroacoustic transducer muchimiro che electrical signal (amplitude modulation), uye chinozoshandurwa kuita ultrasonic field inoshanduka muchimiro che electrical signal. Kana mafungu echiedza apfuura nepakati pe acousto-optic medium, nekuda kwe acousto-optic effect, optical carrier inogadziriswa uye inova intensity modulated wave iyo "inotakura" ruzivo.
Acousto-optic modulator (AOM modulator) inowanzo umbwa nemakristaro e-acousto-optic, matransducer, zvishandiso zvekutora uye madhiraivha. Kubuda kwechiratidzo chakagadziriswa kubva kumutyairi kunoshanda pa transducer muchimiro chechiratidzo chemagetsi uye kunozoshandurwa kuita wave ye ultrasonic inosiyana muchimiro chechiratidzo chemagetsi. Kana wave ye ultrasonic inopfuura nepakati pe acousto-optic medium, inokonzera kudzvanywa kwenzvimbo uye kureba kwechinhu ichi, zvichigadzira elastic strain. Kudzvanywa uku kunochinja nguva nenguva nenzvimbo, zvichiita kuti chinhu ichi chiratidze chiitiko che alternating density, chakafanana ne phase grating. Kana chiedza chikapfuura nepakati pechinhu ichi chakakanganiswa nemafungu e ultrasonic, chiitiko che diffraction chinoitika. Chiitiko ichi chinonzi acousto-optic effect. Pasi pemhedzisiro yeruzha nechiedza, optical carrier inogadziriswa uye inova wave yakagadziriswa "inotakura" ruzivo.
Tsanangura muchidimbu ma parameter makuru
Kushanda zvakanaka kwe diffraction uye kurasikirwa kwe modulation
2. Bragg Angle: Kana chiedza chechiitiko chikaiswa mumudziyo weacousto-opticPaBragg Angle, kushanda zvakanaka kwe diffraction kunogona kuwanikwa. Kukanganisa kwe Angular kunoderedza kushanda zvakanaka.
3. Kuchinjana kweAngle
4. Kumhanya kwekuchinja: Nguva yekuchinja kwe optical inotsanangurwa nenguva yekutumira kweruzha kuburikidza nechiuno chedanda muA0 crystal.
