Xi'an lub koom haum ntawm Optical Mechanics (XIOE) Ua kom muaj kev vam meej hauv Chaw Laser Kev Sib Txuas Lus Capture Thiab Chain Building Research

Tsis ntev los no, Lub Tsev Haujlwm Tseem Ceeb ntawm Kev Ntsuas Kev Ntsuas Tshuab (KLSPMT) ntawm Suav Academy ntawm Kev Tshawb Fawb (CAS) tau ua tiav tshiab hauv qhov chaw laser kev sib txuas lus tau txais thiab tsim cov saw hlau, thiab tau ua tiav qhov kev lees paub hauv lub voj voog, thiab cov txiaj ntsig kev tshawb fawb muaj feem xyuam. tau luam tawm thaum Lub Kaum Ib Hlis 2023 raws li lub npe ntawm On-orbit Space Optical Communication Demonstration nrog 22s Tau Txais Lub Sijhawm. Cov txiaj ntsig kev tshawb fawb tau luam tawm thaum lub Kaum Ib Hlis 2023 hauv Optics Letters, phau ntawv xov xwm ntawm Optical Society of America, nyob rau hauv lub npe ntawm On-orbit Space Optical Communication Demonstration nrog 22s Tau Txais Sijhawm. Cov kws sau ntawv thawj zaug yog Xuan Wang thiab Junfeng Han, cov kws tshawb fawb tshwj xeeb ntawm Optics Tracking Laboratory, thiab tus kws sau ntawv yog Zhiyuan Chang.

Qhov chaw laser txuas kev sib txuas yog qhov tseem ceeb rau kev paub txog qhov chaw laser kev sib txuas lus, thiab yuav ua li cas kom sai thiab ruaj khov ntes thiab tsim qhov txuas hauv lub sijhawm luv luv yog tus yuam sij rau kev vam meej ntawm kev sib txuas lus, yog li kev ua tiav ntawm kev ceev ceev, dav-ntev beam capture thiab ruaj khov high-bandwidth, high-precision beam nrhiav tau dhau los ua cov cuab yeej technology hotspot. Feem ntau, lub davhlau ya nyob twg laser kev sib txuas lus feem ntau yuav tsum tau siv sij hawm ntau los ua kom tiav cov coaxiality nyob rau hauv-orbit calibration ua hauj lwm nyob rau hauv thaum ntxov theem ntawm nkag mus rau lub orbit. Kev txiav txim siab tus cwj pwm yuam kev ntawm satellite platform, orbit yuam kev, cov txheej txheem deformation tshwm sim los ntawm ib puag ncig kev hloov pauv thiab lwm yam laj thawj yuav ua rau muaj qhov tsis paub meej loj (FOU), yog li ua rau qhov nyuaj ntawm kev ntes, thiab kaum tawm ntawm micro-arcs ntawm beam divergence lub kaum ntse ntse. ua rau bidirectional capture nyob rau hauv orbit tsis tshua muaj lo lus nug.
Txhawm rau ua kom tiav cov kev sib txuas lus hauv orbit laser txuas nrawm dua, pab pawg tshawb fawb tau tshaj tawm txoj kev ua kom zoo tshaj plaws nyob rau hauv orbit siv lub installation matrix tsis ntawm laser kev sib txuas lus davhlau ya nyob twg lub hnub qub sensitizer. Txoj kev no tuaj yeem txo qhov yuam kev ntawm kev teeb tsa txoj haujlwm ntawm qhov kho qhov muag axis thiab kev hloov kho qhov tseeb ntawm lub davhlau ya nyob twg laser kev sib txuas lus vim qhov kev ntxhov siab tso tawm ntawm satellite mus rau hauv orbit. Los ntawm kev txawj kho cov teeb meem kev teeb tsa matrix, qhov pib taw qhia qhov tseeb ntawm lub davhlau ya nyob twg laser kev sib txuas lus tuaj yeem txhim kho tau zoo thiab qhov ntau ntawm qhov tsis paub tseeb tuaj yeem raug txo kom tsawg, txhawm rau txhim kho qhov scanning capture qhov tshwm sim ntawm laser kev sib txuas lus davhlau ya nyob twg hauv orbit thiab txo qhov kev ntes. sij hawm.

Qhov kev tshawb fawb ua haujlwm no yog ua raws li ntau qhov theoretical accumululation thiab on-orbit experimental research los ntawm pab neeg tshawb fawb ntawm Optoelectronic Tracking Laboratory, thiab tau txais kev txhawb nqa los ntawm Key Deployment Program ntawm Suav Academy ntawm Sciences thiab National Natural Science Foundation ntawm Tuam Tshoj.
