Nzira mbiri dzekushandamodulator yeacousto-optic
Modulator ye acousto-optic (modulator yeAOM) chishandiso chinogona kuchinja simba kana kutsausa kona yemwaranzi welaser pasina chikonzero chezvikamu zvinofamba-famba zvemacroscopic. Musimboti wayo mukuru uri nyore: kusimudzira mafungu eruzha nenzira inoonekera, kushandisa shanduko dzenguva nenguva dzehuwandu hunokonzerwa nemafungu eruzha kugadzira grating ye diffraction, uye nokudaro kushandura chiedza chinopfuura nepakati paro.
1. Mushure mekupinda mudunhu rePrague, modulator yeAOM ine mashandisirwo maviri ekutanga:
1.1 Kuchinja kwesimba remagetsi: kugadzirisa frequency yeRF uye kuchinja simba reRF. Kuchinja kwesimba remagetsi kunotungamira kuchinjo mukudzika kwegriti, uye simba rechiedza chepakutanga chinochinja zvinoenderana. Kuchinja kwesimba remagetsi kuri nyore iswichi: kana RF yabatidzwa, nzvimbo yechiedza chekutanga inoonekwa; RF yadzimwa, nzvimbo yechiedza chekutanga inonyangarika.
1.2 Kuchinja kwechiedza/kuskena: kuchinja frequency yeRF. Kuchinja kwechiedza kunoita kuti wavelength yewave yeruzha ichinje, uye gritting constant inochinja zvinoenderana, zvichikonzera shanduko mu diffraction angle. Laser beam ichatsauka mukati me angle range diki kwazvo. Kushanda mu mode iyi kunowanzo sanganisira kudaidza optical deflector (AOD).
Hunhu hwe acousto-optic modulator hunogona kunzwisiswa se programmable diffraction grating, iyo inoshandisa masaini eredhiyo kudzora mafungu e ultrasonic, mafungu e ultrasonic kudzora ma parameter e grating, uye ma grating kudzora kutungamira uye simba re laser. Haina macroscopic moving parts uye inogona kupedzisa light switching, dimming, uye small angle scanning nekumhanya kwakanyanya. Kunyangwe mutengo wacho wakakwira uye deflection range yakaganhurirwa, parizvino hapana imwe nzira iri nani pane track ye ultra high speed light control.
Zvakanakira zveAOM modulator kumhanya nekukurumidza, kusapera, uye kunyatsoita zvinhu nemazvo, asi haina kutsiva zvachose mhinduro dzemakanika. Chikonzero chacho chakananga: chimiro chacho chakaoma, mutengo wacho wakakwira, kona yekutsauka idiki kwazvo, uye kushanda kwayo kwakaderera zvakanyanya pane masisitimu emakanika akadai semagirazi nemamota. Saka mumamiriro ezvinhu apo zvinodiwa kumhanya hazvisi zvakanyanya, kutsauka kwemakanika kunowanzova sarudzo iri nani. Kana kumhanya kwemodulation kwasvika MHz kana kupfuura uye chimiro chemakanika chikasakwanisa kuramba chiripo, chinogonazvishandiso zveacousto-opticzvechokwadi hazvigone kutsiviwa.
