Nyob rau hauv lub ntsej muag ntawm lub hom phiaj me me ntawm qhov deb, cov lus pom zoo ib txwm muaj peev xwm feem ntau tsuas yog nyob hauv zos kom pom lub hom phiaj yog qhov taw qhia xwb. Thiab qee qhov kev xav tau tshwj xeeb, qhov yuav tsum tau ua kom paub nws cov yam ntxwv saum npoo thiab txawm tias lub cev tus yam ntxwv, kom ua tiav qhov kev txav ntawm lub hom phiaj kev paub, muaj qhov xav tau sai los tsim cov duab daws teeb meem super. National University of Defense Technology Pulsed Power Laser Technology, tus thawj coj ntawm Lub Xeev Lub Chaw Haujlwm Tseem Ceeb ntawm Xib Fwb Hu Yihua pab pawg, ua raws li kev ua tiav ntawm 10 km nyob rau hauv 2022 zoo dua 2 cm daws teeb meem hauv tsev thiab txawv teb chaws los qhia txog qib siab tshaj plaws ntawm chromatography LIDAR super- daws teeb meem ob-dimensional imaging raws li tsis ntev los no realization ntawm peb-dimensional super-resolution imaging ntawm ib tug loj breakthrough.
Kev paub txog peb-dimensional super-resolution duab nrog 2.0 x 2.0 x 3.5 cm daws teeb meem ntawm qhov deb ntawm 10 km
Lub hauv paus ntsiab lus ntawm ob sab duab duab los ntawm reflectance tomography lidar tau paub tab, thiab cov kev tshawb fawb txog kev tshawb fawb tau ua nyob rau hauv tsev thiab txawv teb chaws, tab sis lub hauv paus ntsiab lus thiab cov qauv ntawm peb-dimensional imaging tsis tau qhia nyob rau hauv tsev thiab txawv teb chaws. Pab neeg innovatively muab tso rau pem hauv ntej lub peb-dimensional imaging technology architecture ntawm reflective chromatography lidar, tsim lub multi-angle thiab multi-field-of-view interleaved sampling ntawm laser nrhiav, high-speed thiab high-fidelity nrhiav tau ntawm nqaim-mem tes laser ncha. , thiab cov duab reconstruction thiab fusion processing txoj kev, thiab tsim peb-dimensional imaging kev sim system ntawm reflective chromatography lidar, thiab ua lub outfield thwmsim nyob rau hauv Zipeng Roob cheeb tsam ntawm Hefei, uas yog nyob deb ntawm 10.38 km, kom paub qhov peb- dimensional super-resolution reconstruction ntawm lub hom phiaj duab. Cov kev sim tau ua nyob rau ntawm qhov deb ntawm 10.38 km hauv Zipeng Roob, Hefei, kom paub txog peb qhov kev daws teeb meem super-resolution ntawm lub hom phiaj duab.
Hauv kev sim, ob hom phiaj tau teeb tsa rau ntawm 100-meter-siab sim ntauwd ntawm lub roob (31 degree 43′28″N, 116 degree 59′55″E): 1) lub tso suab sib dhos nrog qhov siab ntawm 75 cm thiab dav ntawm 30 cm, raws li qhia hauv daim duab 1 (a); 2) 60 degree trapezoidal lub hom phiaj nrog lub kaum sab xis ntawm 60 degree thiab tilting lub kaum sab xis ntawm 60 degree, uas yog tsim los ntawm ntau lub blocks nrog lub thickness ntawm 1.7 cm thiab qhov sib txawv ntawm qhov sib txawv, nrog qhov sib txawv ntawm 9 mus rau 2 cm. los ntawm hauv qab mus rau sab saum toj, thiab nrog ib cheeb tsam ntawm maj mam txo. qaij lub kaum sab xis trapezoidal stereo daws teeb meem kuaj lub hom phiaj, raws li qhia hauv daim duab 1 (b). Cov txheej txheem kev sim duab tau npaj rau pem teb sab saud ntawm South China City (31 degree 46′20″N, 117 degree 5′35″E) hauv nroog, raws li qhia hauv daim duab 1 (c). Raws li ntau yam kev sim ib puag ncig thiab kev sim ntsuas qhov ntsuas, peb-dimensional super-resolution imaging cov txiaj ntsig ntawm lub tso suab lub hom phiaj tau ua tiav tiav raws li qhia hauv Fig. 2 (b) thiab 2 (d).

Raws li lub hauv paus ntsiab lus ntawm reflective chromatography LIDAR imaging, tsuav yog lub teeb liab-rau-suab nrov piv ntawm lub laser pulse echo yog txaus, 3D imaging daws teeb meem kuj yog ywj siab ntawm lub optical aperture, deb, thiab laser divergence kaum, yog li qhov kev sim no nteg lub hauv paus rau kev paub txog 3D duab ntawm cov hom phiaj me me ntawm ultra-ntev nrug ntawm ntau txhiab meters. Yog li ntawd, qhov kev sim no tso lub hauv paus rau kev ua tiav ntawm peb-dimensional imaging ntawm ultra-ntev-ntev me me lub hom phiaj ntawm mais. Lub optical aperture ntawm qhov kev sim yog 260 hli, thiab lub diffraction txwv lub kaum sab xis ntawm lub optical imaging system nrog tib lub aperture yog hais txog 5 μrad, uas sib haum mus rau lub limiting daws teeb meem ntawm pa optical duab ntawm 10 km ntawm txog 5 cm, thiab tam sim no cov txiaj ntsig tau ua tiav qhov kev daws teeb meem zoo tshaj plaws ntawm cov phiaj xwm me me ntawm qhov ntev uas dhau qhov kev txwv tsis pub tshaj ntawm qhov pom kev pom ntawm tib lub aperture, thiab qhov kev daws teeb meem imaging yog nyob rau qib zoo ntawm laser imaging teb hauv tsev thiab txawv teb chaws, tshwj xeeb tshaj yog cov duab stereoscopic ntawm cov khoom me me tau txais thawj zaug los ntawm cov txheej txheem thev naus laus zis thiab kev ua cov algorithms. Cov duab daws teeb meem yog qhov zoo tshaj plaws nyob rau hauv lub tshav pob ntawm laser imaging nyob rau hauv tsev thiab txawv teb chaws, tshwj xeeb tshaj yog thawj zaug kom tau lub centimeter-theem super-resolution 3D imaging tau ntawm peb-dimensional lub hom phiaj qauv ntawm ib tug deb ntawm 10 km los ntawm tus thawj technical txhais tau tias. thiab ua algorithm.
