Hunhu hweAOM acousto-optic modulator
Kushingirira simba repamusoro remaziso
Iyo AOM acousto-optic modulator inogona kumira yakasimba laser simba, ichiona kuti yakakwirira-simba lasers inogona kupfuura nepakati zvakanaka. Mune yese-fiber laser link, iyoFiber acousto-optic modulatorinoshandura chiedza chinoramba chichienderera mberi kuva chiedza chinoputika. Nekuda kweiyo yakaderera duty cycle ye optical pulse, mazhinji emagetsi emwenje ari mukati me zero-order light. Yekutanga-odha diffraction mwenje uye zero-yekurongeka mwenje kunze kweacousto-optic crystal inopararira nenzira yemhando dzakasiyana dzeGaussian matanda. Kunyange zvazvo vachisangana nemamiriro ezvinhu akaoma ekuparadzanisa, chikamu chechiedza chechiedza che zero-order chiedza chinoungana pamucheto we optical fiber collimator uye haigoni kuendeswa kuburikidza ne fiber optical, pakupedzisira inopisa kuburikidza ne optical fiber collimator. Iyo diaphragm chimiro inoiswa munzira yemaziso kuburikidza nepamusoro-chaiyo-chaiyo-nhanhatu-dimensional gadziriso furemu kuti irambidze kutapurirana kwechiedza chakakanganiswa pakati pecollimator, uye zero-yekurongeka mwenje inoendeswa kudzimba kudzivirira zero-kurongeka mwenje kubva pakupisa kunze kweiyo optical fiber collimator.
Kukurumidza kusimuka nguva
Mune yese-fiber laser link, iyo inokurumidza kusimuka nguva yekupuruzira yeAOMacouste-optic modulatorinovimbisa kuti iyo system sign pulse inogona kupfuura nenzira inobudirira kusvika pamwero mukuru, uku ichidzivirira ruzha rwepasi kupinda mukati menguva-domain acouste-optic shutter (nguva-domain pulse gedhi). Iyo yakakosha yekuwana nekukurumidza kusimuka nguva ye optical pulses iri mukudzikisa nguva yekufambisa yemafungu e ultrasonic kuburikidza nemwenje wechiedza. Nzira huru dzinosanganisira kuderedza dhayamita yechiuno chechiitiko chechiedza chechiitiko kana kushandisa zvinhu zvine high sound velocity kugadzira acoust-optic crystals.

Kuderera kwesimba rekushandisa uye yakakwirira kuvimbika
Spacecraft ine zviwanikwa zvishoma, mamiriro akaomarara uye nharaunda dzakaomarara, izvo zvinoisa zvakakwirira zvinodiwa pakushandiswa kwesimba uye kuvimbika kweoptical fiber AOM modulators. Iyo optical fiberAOM modulatorinotora yakakosha tangential acousto-optic crystal, ine yakakwira acousto-optic quality factor M2. Naizvozvo, pasi pemamiriro akafanana ekuita diffraction, iyo inodiwa yekutyaira simba rekushandisa yakaderera. Iyo optical fiber acoust-optic modulator inotora iyi yakaderera-simba dhizaini, iyo isingangodzikisire kudiwa kwekutyaira simba rekushandisa uye kuchengetedza zviwanikwa zvishoma muspacecraft, asi zvakare inodzikisa magetsi emagetsi echiratidzo chekutyaira uye kuderedza kupisa kwekupisa kudzvinyirira pahurongwa. Zvinoenderana nezvinorambidzwa (zvinorambidzwa) zvinodikanwa zvezvigadzirwa zvemuchadenga, iyo yakajairwa kristaro yekumisikidza nzira ye optical fiber acousti-optic modulators inongotora iyo imwe-sided silicone rubber bonding process. Kana iyo silicone rabha ikakundikana, iyo tekinoroji paramita yekristaro ichachinja pasi pemamiriro ekudengenyeka, ayo asingasangane nezvinodiwa zvemaitiro ezvigadzirwa zvemuchadenga. Mune laser link, iyo crystal ye optical fiber acoust-optic modulator inogadziriswa nekubatanidza mechanical fixation nesilicone rubber bonding. Iyo yekumisikidza chimiro chepamusoro uye yakadzika pasi pepamusoro inofananidzwa sezvinobvira, uye panguva imwecheteyo, nzvimbo yekubatana pakati pekristaro pamusoro uye yekuisa imba inokwidziridzwa. Iine zvakanakira simba rakasimba rekupisa kupisa uye symmetrical tembiricha yekugovera munda. Macollimators akajairika anogadziriswa nekubatanidza silicone rubber. Pasi pemamiriro ekupisa kwepamusoro uye kudengenyeka, vanogona kuchinja, zvichikanganisa kushanda kwechigadzirwa. Iyo mechanical chimiro ikozvino yakagamuchirwa kugadzirisa optical fiber collimator, iyo inowedzera kugadzikana kwechigadzirwa uye inosangana nezvinodiwa zvemaitiro ezvigadzirwa zvemuchadenga.
