Xi'an lub koom haum ntawm Optical Mechanics, Suav Academy ntawm Sciences (XIOE, CAS) 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 cov saw hlau tsim thiab ua tiav hauv-orbit validation, thiab cov txiaj ntsig kev tshawb fawb tau luam tawm. Lub Kaum Ib Hlis 2023 nyob rau hauv 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, ib phau ntawv xov xwm ntawm Optical Society of America, nyob rau hauv lub npe ntawm On-orbit Space Optical Communication Demonstration nrog 22s Acquisition Time. Cov kws sau ntawv thawj zaug yog Xuan Wang thiab Junfeng Han, cov kws tshawb fawb tshwj xeeb hauv Optoelectronic 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, yuav ua li cas 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 lub platform satellite, orbital yuam kev, cov qauv deformation tshwm sim los ntawm ib puag ncig kev hloov pauv thiab lwm yam laj thawj yuav ua rau muaj qhov tsis txaus ntseeg loj (FOU), ua ke nrog ntau ntau ntawm micro-arcs ntawm lub beam divergence lub kaum ntse ntse, tag nrho cov yam no yuav ua rau nyob rau hauv-orbit laser capture ua heev nyuaj.

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 qhov 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 kev ntes qhov tshwm sim ntawm laser kev sib txuas lus davhlau ya nyob twg scanning hauv orbit thiab txo qhov kev ntes. sij hawm.

Qhov kev tshawb fawb no yog ua raws li ntau qhov kev xav tau thiab kev tshawb fawb ntawm lub voj voog los ntawm pab pawg tshawb fawb ntawm Optoelectronic Tracking Laboratory, uas tau txais kev txhawb nqa los ntawm Qhov Kev Pabcuam Tseem Ceeb ntawm Suav Academy of Sciences (CAS) thiab National Natural Science Foundation. ntawm Tuam Tshoj (NSFC).
