Optical Innovation: Holographic Codes ntawm Micromachining thiab AR
Lub hauv paus ntsiab lus ntawm holographicpob zeb engravedlus dag nyob rau hauv lub creation ntawm "invisible ntaub ntawv txheej." Cov pab pawg kws tshaj lij siv femtosecond lasers los ua 5μm-precision micromachining ntawm lub pob zeb nto, ua ib nano- nplai diffraction grating txheej- cov qauv siv microscopic no (nrog kab dav ntawm tsuas yog 200nm, 1/500 txoj kab uas hla ntawm tib neeg cov plaub hau) cuam tshuam cov qauv zoo li "optical teeb pom kev zoo" los yog xov tooj flash).
Thaum lub AR- qhib lub cuab yeej (xov tooj lossis lub tshuab scanner tshwj xeeb) paub txog cov qauv no, nws tam sim ntawd ua rau 3D holographic dluab: uas tuaj yeem yog cov ntawv dynamic, 3D qauv, lossis txawm tias ib qho kev ua yeeb yam. Piv txwv li, scanning lub cobblestone engraved nrog "Lanting Xu" (Preface rau lub Lanting Collection) yuav ua rau lub AR system project ib tug holographic duab ntawm Wang Xizhi wielding nws txhuam, nrog rau stereoscopic kev nthuav qhia ntawm cov lus piav qhia. Cov thev naus laus zis no ua tiav "ib pob zeb, ib lub ntiaj teb" cov nyhuv- lub pob zeb zoo nkauj ua haujlwm raws li lub hauv paus pom, thaum cov duab holographic txuas ntxiv cov ntaub ntawv, nrog rau ob qho tib si seamlessly merging visually. Cov neeg saib tuaj yeem saib lub hologram nrog lub qhov muag liab qab, tsis muaj cov cuab yeej tshwj xeeb xav tau.
Cov kev ntsuam xyuas qhia tau hais tias ib lub pob zeb pob zeb tuaj yeem khaws cia txog 2GB ntawm cov ntaub ntawv holographic, txhawb nqa kev ua yeeb yaj kiab dynamic txog li 3 feeb nrog 4K daws teeb meem, tseem pom tau txawm tias nyob hauv tshav ntuj (qhov sib piv ntau dua lossis sib npaug rau 1000: 1).
Daim Ntawv Thov Scenario: Los ntawm Kev Txhais Lus Henplais mus rau Kev Ua Cultural Activation
Lub Tsev khaws puav pheej Palace's "Digital Heritage Guide Stones" qhov project stands raws li daim ntawv teev npe. Ib sab ntawm 10 keeb kwm relics hauv Hall of Supreme Harmony square, tshwj xeeb tshaj yog xaiv dawb marble cobblestones (nrog rau saum npoo micromachined diffraction txheej) tau muab tso rau. Thaum cov neeg tuaj saib xyuas lawv nrog Palace Tsev khaws puav pheej lub official APP, lub pob zeb "float" holographic dluab: ib co recreate scenes ntawm Ming Dynasty craftsmen tsim lub palace, ib co tso saib cov xwm txheej loj keeb kwm uas tshwm sim ntawm qhov chaw (xws li imperial neeg tuaj saib), thiab txawm tso cai rau sib tham sib 3D qauv disassembly ntawm thoob arches ntawm gestures.
Qhov no daws cov kev txwv ntawm cov cuab yeej cuab tam cov cim: ua ntej, zam qhov tsis sib haum xeeb ntawm cov hlau lossis acrylic kos npe nrog cov cuab yeej qub qub -natural textures ntawm cobblestones blends seamlessly nrog Palace Tsev khaws puav pheej ib puag ncig; thib ob, dynamic holograms nyiam cov neeg tuaj xyuas kom nyob ntev (nruab nrab lub sijhawm nyob ntev ntawm 40 vib nas this mus rau 3 feeb); thib peb, cov ntsiab lus tuaj yeem hloov kho hauv lub sijhawm tiag tiag -, xws li hloov cov lus piav qhia rau lub sijhawm keeb kwm sib txawv raws li cov ntsiab lus nthuav qhia, yam tsis tau hloov lub cev kos npe.
Tshaj li qhov chaw ntawm kev coj noj coj ua, thev naus laus zis nkag mus rau qhov xwm txheej nco txog: scanning cobblestones ntawm ib sab ntawm martyrs 'monuments qhia txog holographic biography; Nyob rau hauv tsev neeg memorial vaj, pob zeb khaws cov dab neeg holographic, paub txog kev xav qub txeeg qub teg uas "pob zeb hais tau."
Durability Test: Cov ntaub ntawv Fidelity dhau sijhawm
Rau kev siv sab nraum zoov, holographic engraved pob zeb tau dhau los ua pov thawj kev ruaj khov. Kev ntsuas kev laus nrawm raws li ISO 4892-3 (Plastics-Txoj kev raug rau lub chaw kuaj teeb pom kev) qhia: tom qab 5000 teev ntawm kev simulated sab nraum zoov raug (UV siv 0.76W / m², kub 60℃, av noo 50%) {enterprise 50 xyoo{9} laser-micromached diffraction txheej decays los ntawm tsuas yog 2.8%, nrog holographic duab ci ci thiab clarity tuav ntau tshaj 97%.
Qhov no yog vim muaj kev tiv thaiv dual: ua ntej, 1μm- tuab silica tiv thaiv zaj duab xis (hardness 9H) npog txheej diffraction, tiv taus cua, nag, thiab kev sib txhuam me; Thib ob, UV- tiv taus tshwj xeeb laser engraving tsis txhob fading teeb meem ntawm tsoos inks lossis pigments. Hauv kev siv tswv yim, cov pob zeb sim muab tso rau hauv qhov qhib- thaj chaw huab cua ntawm Dunhuang Mogao Grottoes khaws tag nrho holographic functionality tom qab 3 xyoos ntawm cov xuab zeb thiab cua yaig, ua pov thawj hloov mus rau qhov chaw huab cua.
