Tsarin tsarin na acousto-optical modulator

Tsarin tsarinmai daidaita yanayin gani na acousto-optical
Acoustic Optical Modulator (AOM Modulator) a halin yanzu ita ce na'urar da aka fi amfani da ita wajen sarrafa na'urar laser, wacce take cikin tsarin fasahar gyaran fuska ta waje. Tana dogara ne akan tasirin zahiri na haɗin acousto-optic don cimma kunnawa/kashe haske, ƙarfi da sarrafa mita. Ita ce tsarin gyaran fuska da aka fi amfani da shi a cikin alamar laser ta masana'antu, yankewa daidai, hanyar gani ta bincike ta kimiyya, da kayan aikin radar laser masu ƙarfi da matsakaici.
Tsarin tsarin,
Cikakkendaidaitawar acousto-opticTsarin ya ƙunshi manyan raka'a guda biyar: kristal mai kama da acousto-optic, mai canza piezoelectric, tushen tuƙi na RF, tushen watsa zafi, da tushen haɗin kai na gani. Kowane module yana aiki tare don tabbatar da daidaiton daidaitawa.
1. Gilashin Acousto na gani: Babban mai ɗaukar hulɗar acousto-optic, wanda shine babban kayan da ke ƙayyade ma'aunin mitar daidaitawa, ma'aunin mitar watsawa, da kuma matakin lalacewa. An raba lu'ulu'u da aka saba amfani da su zuwa rukuni uku: ma'aunin quartz mai haɗawa wanda ya dace da laser 1064nm/CO ₂, wanda ya dace da yanayin masana'antu masu ƙarfi; TeO ₂ yana da kyawawan halaye masu yawa kuma tsari ne na yau da kullun don ƙananan da matsakaitan injunan alamar wutar lantarki; Gallium phosphide ya dace da laser ultraviolet 355nm don yin aiki daidai.
2. Mai canza wutar lantarki na Piezoelectric: an manna shi a kan fuskar ƙarshen lu'ulu'u don cimma canjin lantarki, samfuran masu inganci suna ɗaukar tsarin walda mai ƙarancin zafin jiki don inganta aminci.
3. Tushen direban RF: cibiyar sarrafa lantarki, an raba shi zuwa rukuni biyu: Direban dijital na TTL ya dogara da matakai masu girma da ƙananan don kunnawa da kashe RF, wanda shine babban mafita don alamar masana'antu; Tukin da aka kwaikwayi yana cimma ci gaba da daidaita ƙarfin haske ta hanyar daidaita ƙarfin RF, wanda aka saba amfani da shi a cikin yanayin binciken kimiyya. Matsakaicin mitar tuki na al'ada shine 20MHz ~ 400MHz.
4. Tushen watsa zafi: babban ikoMai daidaita AOMtare da sanyaya ruwa, sanyaya iska ta ƙarfen aluminum don ƙarami da matsakaiciyar ƙarfi don guje wa lalacewar yanayin zafi mai yawa na ingancin watsawa.
5. Tushen gani: Daidaitaccen kayan aiki wanda zai iya daidaita kusurwar abin da ya faru don tabbatar da cewa laser ɗin ya faru a kusurwar Bragg.
