He aha ka acousto-optic modulatorAOM modulator

ʻO ka modulation Acousto-optic kahi ʻenehana modulation waho. ʻO ka mea maʻamau, ua kapa ʻia ka mea acousto-optic e hoʻomalu i ka hoʻololi ʻana i ka ikaika o ka kukuna laseracousto-optic modulator(AOM modulator). ʻO ka hōʻailona modulated e hana ma luna o ka transducer electroacoustic ma ke ʻano o ka hōʻailona uila (amplitude modulation), a laila hoʻololi ʻia i kahi kahua kani ultrasonic e hoʻololi i ke ʻano o kahi hōʻailona uila. Ke hele ka nalu māmā ma o ka acousto-optic medium, ma muli o ka hopena acousto-optic, hoʻololi ʻia ka mea lawe optical a lilo i nalu modulated ikaika e "lawe" i ka ʻike.

Acousto-optic modulationHe kaʻina hana kino e hoʻohana ana i ka hopena acousto-optic e hoʻouka i ka ʻike ma luna o kahi mea lawe alapine optical. ʻO ka hōʻailona modulated e hana ma luna o ka transducer electroacoustic ma ke ʻano o ka hōʻailona uila (amplitude modulation), a laila hoʻololi ʻia i kahi kahua kani ultrasonic e hoʻololi i ke ʻano o kahi hōʻailona uila. Ke hele ka nalu māmā ma o ka acousto-optic medium, ma muli o ka hopena acousto-optic, hoʻololi ʻia ka mea lawe optical a lilo i nalu modulated ikaika e "lawe" i ka ʻike.

ʻO kahi modulator acousto-optic (AOM modulator) ka mea maʻamau i haku ʻia me nā kristal acousto-optic, transducers, absorption device a me nā mea hoʻokele. ʻO ka hoʻopuka hōʻailona modulated mai ka mea hoʻokele e hana i ka transducer ma ke ʻano o kahi hōʻailona uila a laila hoʻololi ʻia i loko o kahi hawewe kani ultrasonic e ʻokoʻa i ke ʻano o kahi hōʻailona uila. Ke hele ka hawewe kani ultrasonic ma ka acousto-optic medium, hoʻoulu ia i ka hoʻopiʻi kūloko a me ka hoʻolōʻihi ʻana o ka mea waena, e hoʻohua ai i ka elastic strain. Hoʻololi pinepine kēia ʻano me ka manawa a me ka lewa, e hōʻike ana ka mea kikowaena i kahi ʻano ʻano like ʻole, e like me ka pae pae. Ke hele ka malamalama ma kēia ʻano i hoʻopilikia ʻia e nā hawewe kani ultrasonic, hiki mai kahi ʻano ʻokoʻa. Kapa ʻia kēia hanana ka hopena acousto-optic. Ma lalo o ka hopena o ke kani a me ka māmā, hoʻololi ʻia ka mea lawe optical a lilo i nalu modulated e "lawe" i ka ʻike.

E wehewehe pōkole i nā palena nui

ʻO ka maikaʻi o ka diffraction a me ka nalowale modulation

2. Bragg Angle: Ke hoʻokomo ʻia ke kukui hanana i loko o kahimea acousto-opticma kahi Bragg Angle, hiki ke hoʻokō ʻia ka maikaʻi o ka diffraction maikaʻi loa. ʻO nā hewa angular e hōʻemi i ka pono.

3. Ka hoʻololi ʻana i ka Angle Divergence

4. Ka wikiwiki o ka hoʻololi ʻana: Ua wehewehe ʻia ka manawa hoʻololi optical e ka manawa hoʻouna o ka hawewe kani ma o ka pūhaka beam i ka aniani A0.
