Izindlela ezimbili zokusebenzai-modulator ye-acousto-optic
I-modulator ye-acousto-optic (I-modulator ye-AOM) iyithuluzi elingashintsha ubukhali noma liphambukise i-engeli yomsebe we-laser ngaphandle kwesidingo sanoma yiziphi izingxenye ezihambayo ze-macroscopic. Isimiso salo esiyinhloko silula: ukuvusa amaza omsindo endaweni ecacile, ukusebenzisa izinguquko zesikhathi eside zobuningi ezibangelwa amaza omsindo ukwakha i-diffraction grating, ngaleyo ndlela kushintshe ukukhanya okudlula kuyo.
1. Ngemva kokungena esifundeni sasePrague, i-modulator ye-AOM inezindlela ezimbili eziyisisekelo zokusebenzisa:
1.1 Ukuguqulwa kwamandla: ukulungisa imvamisa ye-RF nokushintsha amandla e-RF. Ushintsho kwamandla omsindo luholela ekushintsheni ekujuleni kwe-grating, futhi amandla okukhanya kwe-diffract yokuqala ashintsha ngokufanele. Ukuguqulwa kwamandla okulula kakhulu ukushintsha: lapho i-RF ivuliwe, kuvela indawo yokukhanya yezinga lokuqala; i-RF icishiwe, indawo yokukhanya yezinga lokuqala iyanyamalala.
1.2Ukuphambuka/ukuskena kwe-beam: ukushintsha imvamisa ye-RF. Ukushintsha kwemvamisa kubangela ukuthi ubude be-wave wave yomsindo bushintshe, kanye nokuguquguquka kwe-grating ngokufanele, okuholela ekushintsheni kwe-engeli ye-diffraction. Ububanzi be-laser buzophambuka ngaphakathi kwebanga elincane kakhulu le-engeli. Ukusebenza kule modi kuvame ukuhilela ukubiza i-optical deflector (AOD).
Ingqikithi ye-acousto-optic modulator ingaqondwa njenge-diffraction grating ehlelekayo, esebenzisa amasignali emvamisa yomsakazo ukulawula amagagasi e-ultrasonic, amagagasi e-ultrasonic ukulawula amapharamitha e-grating, bese kuba ama-grating ukulawula isiqondiso kanye namandla e-laser. Ayinazo izingxenye ezihambayo ezinkulu futhi ingaqedela ukushintsha kokukhanya, ukufiphaza, kanye nokuskena kwe-engeli encane ngesivinini esikhulu kakhulu. Nakuba izindleko ziphezulu futhi ububanzi bokuphambuka bulinganiselwe, okwamanje asikho esinye isisombululo esingcono endleleni yokulawula ukukhanya kwesivinini esikhulu kakhulu.
Izinzuzo ze-AOM modulator isivinini esisheshayo, akukho ukuguguleka, kanye nokunemba okuphezulu, kodwa ayikazishintshi ngokuphelele izixazululo zemishini. Isizathu siqondile kakhulu: isakhiwo siyinkimbinkimbi, intengo iphezulu, i-engeli yokuphambuka incane kakhulu, futhi ukusebenza kahle kuphansi kakhulu kunezinhlelo zemishini ezifana nezibuko nama-motor. Ngakho-ke ezimweni lapho izidingo zesivinini zingekho phezulu, ukuphambuka kwemishini cishe njalo kuyisinqumo esingcono. Kuphela uma isivinini sokushintsha sifinyelela ku-MHz noma ngaphezulu futhi isakhiwo semishini singakwazi ukuhambisana, singakwazi.amadivayisi e-acousto-opticngempela kube yinto engenakuphikwa.
