IbirangaModulator ya AOM acousto-optic

Ihangane n'imbaraga nyinshi z'urumuri

Modulator ya AOM acousto-optic ishobora kwihanganira imbaraga zikomeye za laser, bigatuma laser zifite imbaraga nyinshi zishobora kunyura neza. Mu ihuriro rya laser ifite fiber zose,modulator ya fibre acousto-opticBihindura urumuri ruhoraho mu rumuri ruhindagurika. Bitewe n'imikorere mike y'urumuri ruhindagurika, ingufu nyinshi z'urumuri ziba mu rumuri rwa zeru. Urumuri rwa diffraction rwo mu cyiciro cya mbere n'urumuri rwa zeru rwo hanze ya acousto-optic crystal bikwirakwira mu buryo bw'imirasire ya Gaussian itandukanye. Nubwo byujuje ibisabwa byo gutandukana, igice cy'ingufu z'urumuri rwa zeru ruhurira ku nkengero za collimator ya optique kandi ntirushobora koherezwa binyuze muri fibre optique, amaherezo rucanwa binyuze muri collimator ya optique. Imiterere ya diaphragm ishyirwa mu nzira ya optique inyuze mu buryo bworoshye bwo guhindura urumuri rufite imiterere itandatu kugira ngo ibuze kohereza urumuri ruhindagurika hagati muri collimator, kandi urumuri rwa zeru rwoherezwa mu cyumba kugira ngo hirindwe ko urumuri rwa zeru rwoherezwa gutwika collimator ya optique.

Igihe cyo kuzamuka vuba

Mu buryo bwa laser ikoresha fiber gusa, igihe cyo kuzamuka vuba kw'ingufu z'amajwi za AOMmodulator ya acouste-opticItuma umuvuduko w'ikimenyetso cya sisitemu ushobora kunyura neza ku rugero runini, mu gihe ikumira urusaku rw'ibanze kwinjira muri shutter ya acouste-optic shutter (irembo rya pulse ya time-domain). Ishingiro ryo kugera ku gihe cyo kuzamuka vuba kwa optique ni ukugabanya igihe cy'imiraba ya ultrasound inyura mu rumuri. Uburyo bw'ingenzi burimo kugabanya umurambararo w'urumuri rw'urumuri cyangwa gukoresha ibikoresho bifite umuvuduko mwinshi w'amajwi kugira ngo bikore kristu za acoust-optic.

Igishushanyo cya 1 Igihe cyo kuzamuka k'umuvuduko w'urumuri

Ingufu nke zikoreshwa kandi zizewe cyane

Icyogajuru gifite ubushobozi buke, imiterere mibi n'ibidukikije bigoye, ibyo bikaba bisaba ingufu nyinshi zikoreshwa n'uburyo bwo gukora neza bwa fibre optique AOM modulators.Modulator ya AOMikoresha kristu yihariye ya tangential acousto-optic, ifite factor M2 ifite ubwiza bwa acousto-optic bwinshi. Kubwibyo, muri ubwo buryo bumwe bwo gukora neza, ingufu zisabwa zo gutwara ni nke. Modulator ya fibre optique acoust-optic ikoresha iyi miterere y'ingufu nke, itagabanya gusa icyifuzo cyo gukoresha ingufu zo gutwara kandi ikagabanya umutungo muke mu byogajuru, ahubwo inagabanya imirasire ya elegitoroniki y'ikimenyetso cyo gutwara kandi ikagabanya umuvuduko wo gukwirakwiza ubushyuhe kuri sisitemu. Dukurikije ibisabwa (bibujijwe) by'ibikorwa by'ibyogajuru, uburyo busanzwe bwo gushyiraho kristu ya fibre optique acousti-optic modulators bukoresha gusa inzira yo guhuza silicone rubber ku ruhande rumwe. Iyo silicone rubber inaniwe, ibipimo bya tekiniki bya kristu bizahinduka bitewe n'ibihe byo guhindagura, bidahuye n'ibisabwa by'ibikorwa by'ibikoresho byo mu kirere. Muri laser link, kristu ya fibre optique acoust-optic modulator ishyirwaho binyuze mu guhuza fixation ya mechanical na silicone rubber bonding. Imiterere y'aho ushyira ibintu hejuru n'aho hasi ni ingano ishoboka, kandi icyarimwe, ahantu hahurira abantu hagati y'ubuso bwa kristu n'aho ushyira ibintu ni heza cyane. Ifite ibyiza byo gukwirakwiza ubushyuhe bwinshi n'ubushyuhe bungana. Ama-collimator asanzwe ashyirwaho hakoreshejwe silicone rubber. Mu gihe cy'ubushyuhe bwinshi n'ihindagurika, ashobora guhinduka, bigatuma umusaruro uhinduka. Imiterere y'imashini ubu yakoreshejwe kugira ngo ikosore collimator ya fibre optique, yongera ubushobozi bwo guhagarara neza kw'ibicuruzwa kandi ihuze n'ibisabwa mu mikorere y'ibicuruzwa byo mu kirere.
