Iindlela ezimbini zokusebenzai-modulator ye-acousto-optic
Imodulator ye-acousto-optic (Imodulator ye-AOM) sisixhobo esinokuguqula amandla okanye sijike i-engile yomqadi welaser ngaphandle kwesidingo sazo naziphi na iindawo ezihambayo ze-macroscopic. Umgaqo waso oyintloko ulula: vuselela amaza esandi kwindawo ebonakalayo, sebenzisa utshintsho oluqhubekayo loxinano olubangelwa ngamaza esandi ukwenza i-diffraction grating, ngaloo ndlela utshintshe ukukhanya okudlula kuyo.
1. Emva kokungena kwisithili sasePrague, i-modulator ye-AOM ineendlela ezimbini ezisisiseko zokusetyenziswa:
1.1 Ukuguqulwa kwamandla: ukulungisa i-RF frequency kunye nokutshintsha amandla e-RF. Utshintsho kubunzulu besandi lukhokelela kutshintsho kubunzulu be-grating, kwaye amandla okukhanya okudityanisiweyo komyalelo wokuqala atshintsha ngokufanelekileyo. Ukuguqulwa kwamandla okulula kukutshintsha: xa i-RF ivuliwe, kuvela indawo yokukhanya kwinqanaba lokuqala; i-RF icinyiwe, indawo yokukhanya kwinqanaba lokuqala iyanyamalala.
1.2Ukujika/ukuskena kwemitha: ukutshintsha i-RF frequency. Utshintsho lwemitha lubangela ukuba ubude be-wave yesandi butshintshe, kwaye i-grating constant itshintsha ngokufanelekileyo, nto leyo ebangela utshintsho kwi-angle ye-diffraction. Umqadi we-laser uya kujika ngaphakathi koluhlu lwe-angle oluncinci kakhulu. Ukusebenza kule ndlela kudla ngokubandakanya ukubiza i-optical deflector (AOD).
Ingqwalasela ye-acousto-optic modulator inokuqondwa njenge-programmable diffraction grating, esebenzisa imiqondiso yerediyo ukulawula amaza e-ultrasonic, amaza e-ultrasonic ukulawula iiparameter ze-grating, kunye nee-grating ukulawula ulwalathiso kunye nobukhali be-laser. Ayinazo iindawo ezihambayo ze-macroscopic kwaye inokugqiba ukutshintsha ukukhanya, ukufiphala, kunye nokuskena kwe-engile encinci ngesantya esiphezulu kakhulu. Nangona ixabiso liphezulu kwaye uluhlu lokuphambuka lulinganiselwe, okwangoku akukho sisombululo singcono kwindlela yokulawula ukukhanya okukhawulezayo kakhulu.
Iingenelo ze-AOM modulator zisantya esikhawulezayo, akukho kuguga, kunye nokuchaneka okuphezulu, kodwa azikatshintshi ngokupheleleyo izisombululo zoomatshini. Isizathu sithe ngqo kakhulu: ulwakhiwo luyinkimbinkimbi, ixabiso liphezulu, i-engile yokuphambuka incinci kakhulu, kwaye ukusebenza kakuhle kuphantsi kakhulu kuneenkqubo zoomatshini ezifana nezipili kunye neemoto. Ngoko ke kwiimeko apho iimfuno zesantya zingekho phezulu, ukuphambuka koomatshini phantse kusoloko kuyindlela engcono. Kuphela xa isantya sokuguquguquka sifikelela kwi-MHz okanye ngaphezulu kwaye isakhiwo soomatshini singakwazi ukuqhubeka, sinokukwazi.izixhobo ze-acousto-opticngenene akunakuthathelwa indawo.
