Iimpawu zeImodyuli ye-acousto-optic ye-AOM
Ukumelana namandla aphezulu optical
Imodyuli ye-acousto-optic ye-AOM inokumelana namandla e-laser eyomeleleyo, iqinisekisa ukuba iilaser zamandla aphezulu zinokudlula ngokutyibilikayo. Kwikhonkco le-laser ye-fiber yonke, ii-fiber acousto-optic imodyuliiguqula ukukhanya okuqhubekekayo kube kukukhanya okupholileyo. Ngenxa yomjikelo ophantsi womsebenzi we-optical pulse, uninzi lwamandla okukhanya afumaneka ngaphakathi kwesibane se-zero-odolo. Ukukhanya komyalelo wokuqala we-diffraction kunye nokukhanya kwe-zero-odolo ngaphandle kwekristale ye-acousto-optic isasazeke ngendlela yokwahlukana kwemiqadi yeGaussian. Nangona zihlangabezana neemeko ezingqongqo zokuhlukana, inxalenye yamandla okukhanya okukhanya kwe-zero-oda iqokelela kumda we-fiber optical fibre collimator kwaye ayikwazi ukuhanjiswa nge-fiber optical, ekugqibeleni ivutha nge-fiber optical collimator. Isakhiwo se-diaphragm sibekwe kwindlela ye-optical ngokusebenzisa i-high-precision six-dimensional adjustment frame ukukhawulela ukuhanjiswa kokukhanya okungafaniyo kumbindi we-collimator, kwaye ukukhanya kwe-zero-odolo kudluliselwa kwizindlu ukukhusela ukukhanya kwe-zero-odolo ekutshiseni i-fiber optical collimator.
Ixesha lokunyuka ngokukhawuleza
Kwikhonkco ye-laser ye-fiber yonke, ixesha lokunyuka ngokukhawuleza kwe-pulse optical ye-AOMimodyuli ye-acouste-opticiqinisekisa ukuba i-pulse yesignali yenkqubo inokudlula ngokufanelekileyo ukuya kwinqanaba elikhulu, ngelixa likhusela ingxolo yesiseko ekungeneni kwi-time-domain acouste-optic shutter (ixesha-domain pulse gate). Undoqo ekufezekiseni ixesha lokunyuka ngokukhawuleza kwee-pulses optical lilele ekunciphiseni ixesha lokuhamba kwamaza e-ultrasonic ngokusebenzisa umqadi wokukhanya. Iindlela eziphambili ziquka ukunciphisa ububanzi besinqeni sesiganeko sokukhanya kwesiganeko okanye ukusebenzisa izinto ezinesantya esiphezulu somsindo ukwenza iikristale ze-acoust-optic.

Ukusetyenziswa kwamandla aphantsi kunye nokuthembeka okuphezulu
I-Spacecraft inezixhobo ezinqongopheleyo, iimeko ezinzima kunye neemeko ezinzima, ezibeka iimfuno eziphezulu kusetyenziso lwamandla kunye nokuthembeka kweemodyuli ze-fiber optical AOM. Ifiber opticalImodyuli ye-AOMYamkela ikristale ekhethekileyo ye-tangential acousto-optic, enomgangatho ophezulu we-acousto-optic factor M2. Ngoko ke, phantsi kweemeko ezifanayo ze-diffraction, ukusetyenziswa kwamandla okuqhuba okufunekayo kuphantsi. Imodyuli ye-fiber acoust-optic ye-optical fiber ithatha olu luyilo lwamandla aphantsi, olunganciphisi kuphela imfuno yokuqhuba ukusetyenziswa kwamandla kunye nokugcina izixhobo ezilinganiselweyo kwi-spacecraft, kodwa yehlisa imitha ye-electromagnetic yesiginali yokuqhuba kwaye ithomalalise uxinzelelo lokuchitha ubushushu kwinkqubo. Ngokweemfuno ezithintelweyo (ezithintelweyo) zenkqubo yeemveliso zesphekepheke, indlela eqhelekileyo yofakelo lwekristale yeemodyuli zefiber acousti-optic zamkela kuphela inkqubo yerabha yerabha enecala elinye. Emva kokuba i-rubber ye-silicone ingaphumeleli, iiparitha zobugcisa ze-crystal ziya kutshintsha phantsi kweemeko zokungcangcazela, ezingahambelani neemfuno zenkqubo yeemveliso ze-aerospace. Kwikhonkco ye-laser, i-crystal ye-fiber optical acoust-optic modulator igxininiswe ngokudibanisa ukulungiswa komatshini kunye ne-silicone ye-rubber bonding. Isakhiwo sofakelo lweendawo eziphezulu kunye nezantsi ezisezantsi zinokulinganisa ngokusemandleni, kwaye ngexesha elifanayo, indawo yokudibanisa phakathi kwendawo ye-crystal kunye nendlu yokufakela iyanda. Ineenzuzo zomthamo oqinileyo wokutshatyalaliswa kobushushu kunye nokuhanjiswa kwentsimi yobushushu obulinganayo. Ii-collimators eziqhelekileyo zilungiswe ngokudibanisa irabha ye-silicone. Ngaphantsi kweemeko zokushisa okuphezulu kunye nokungcangcazela, banokutshintsha, okuchaphazela ukusebenza kwemveliso. Isakhiwo somatshini ngoku samkelwe ukulungisa i-fiber collimator ye-optical, eyandisa ukuzinza kwemveliso kwaye ihlangabezana neemfuno zenkqubo yeemveliso ze-aerospace.
