Dab tsi yog qhov txawv ntawm lub hologram thiab 3D hologram?
Taw qhia:
Holograms tau txaus siab rau tib neeg rau ntau xyoo, muab kev pom rau hauv lub ntiaj teb uas cov duab tuaj yeem hloov kho thiab tshwm sim hauv peb qhov ntev. Kev nce qib hauv thev naus laus zis tau tso cai rau kev txhim kho ntau hom holograms, suav nrog 3D holograms. Thaum ob qho tib si holograms thiab 3D holograms tsim peb-dimensional illusions, muaj qhov sib txawv tseem ceeb ntawm ob. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv no hauv kev nthuav dav thiab pom lub ntsiab lus ntawm holography thiab 3D holography.
Keeb kwm thiab lub hauv paus ntawm Holography:
Lub tswv yim ntawm holography tau qhia los ntawm Hungarian-British physicist Dennis Gabor nyob rau hauv 1947. Holography yog ib tug txheej txheem uas ntes cov kev cuam tshuam cov qauv ntawm ob coherent lub teeb ci thiab txheej txheem nws los tsim ib tug peb-dimensional sawv cev ntawm ib yam khoom. Cov txheej txheem no suav nrog kev siv lub teeb laser thiab cov duab thaij duab lossis holographic zaj duab xis.
Ib qho kev cai hologram yog tsim los ntawm kev faib ib lub laser beam rau hauv ob qhov chaw: cov khoom beam thiab cov khoom siv beam. Cov khoom beam illuminates cov khoom, thiab ib co ntawm cov teeb yog tawg tawm ntawm cov khoom mus rau lub holographic zaj duab xis. Cov kab lus siv, uas tsis hloov pauv los ntawm cov khoom, kuj tseem pom cov duab holographic. Thaum ob kab teeb no sib ntsib ntawm zaj duab xis, ib qho kev cuam tshuam tus qauv tsim, uas ua rau tsim ib lub hologram.
Cov khoom thiab cov yam ntxwv ntawm Holograms:
Holograms muaj ntau yam khoom tshwj xeeb thiab cov yam ntxwv uas ua rau lawv txawv ntawm cov duab lossis cov duab. Qee yam ntawm cov khoom no muaj xws li:
1. Parallax: Holograms muab cov kev xav sib txawv ntawm ib qho khoom thaum pom los ntawm cov ces kaum sib txawv vim muaj cov nyhuv parallax. Qhov no tsim qhov illusion ntawm qhov tob thiab muab lub tswv yim tias cov khoom holographic yog peb-dimensional tiag tiag.
2. Kev sib tham sib: Nrog holography, nws muaj peev xwm los tsim kev sib tham sib holographic qhia uas teb rau tus neeg saib cov kev txav los yog cov khoom siv. Qhov no ntxiv ib txheej ntxiv ntawm kev koom tes thiab kev muaj tiag rau qhov kev paub holographic.
3. Lub teeb Diffraction: Holograms cuam tshuam lub teeb nyob rau hauv ib yam uas khaws cia ob qho tib si amplitude thiab theem cov ntaub ntawv ntawm cov khoom raug kaw. Qhov kev khaws cia ntawm cov ntaub ntawv theem no ua rau pom qhov tseeb ntawm holograms.
4. Txwv Saib lub kaum sab xis: Holograms muaj qhov txwv saib lub kaum ntse ntse, txhais tau hais tias lawv tsuas tuaj yeem pom kom meej los ntawm ntau qhov ntawm cov ces kaum. Qhov kev txwv no yog vim qhov tshwm sim ntawm cov nyhuv parallax thiab cov qauv cuam tshuam yuav tsum tau tsim cov hologram.
Taw qhia rau 3D Holography:
Thaum holography nws tus kheej tsim peb-seem sawv cev, lo lus "3D holography" feem ntau yog siv los xa mus rau ib hom holography uas siv volumetric lossis txav holograms. Cov holograms no feem ntau pom nyob rau hauv cov yeeb yaj kiab kev tshawb fawb los yog cov duab futuristic uas cov khoom tshwm sim ntab dawb hauv qhov chaw.
Sau thiab tso saib ntawm 3D Holograms:
Cov txheej txheem kaw rau 3D holography yog qhov nyuaj dua li cov qauv holography. Hloov chaw ntawm kev ntes ib qho kev cuam tshuam ib qho qauv siv cov khoom zoo li qub thiab siv cov nqaj, 3D holography suav nrog kev sau ntau yam cuam tshuam los ntawm ntau lub kaum ntse ntse. Qhov no ua tiav los ntawm kev siv lub koob yees duab array lossis lasers nyob ib ncig ntawm cov khoom.
Thaum lub hologram kaw lawm, nws tuaj yeem tso tawm tau siv ntau yam txuj ci. Txoj kev siv ntau tshaj plaws yog siv cov holographic zaub, uas muaj cov phaj tshwj xeeb lossis nruab nrab uas tawm lub teeb nyob rau hauv ib txoj kev uas rov tsim cov ntaub ntawv hologram. Cov zaub no tuaj yeem yog qhov zoo li qub 3D hologram lossis txav hologram, nyob ntawm qhov nyuaj ntawm kev kaw.
Qhov sib txawv ntawm Holograms thiab 3D Holograms:
Tam sim no peb tau tshawb xyuas qhov tseem ceeb ntawm ob qho tib si holography thiab 3D holography, cia peb hais txog qhov sib txawv tseem ceeb ntawm ob:
1. Cov txheej txheem kaw: Traditional holograms xav tau cov ntaub ntawv ntawm ib qho kev cuam tshuam tus qauv, thaum 3D holograms koom nrog kev ntes ntau tus qauv los ntawm ntau lub kaum ntse ntse.
2. Saib lub kaum sab xis: Holograms muaj lub kaum sab xis pom tsawg, qhov 3D holograms tso cai rau saib los ntawm ntau lub ces kaum, feem ntau muab 360-degree foundations.
3. Depth Perception thiab Realism: Holograms muab kev nkag siab tob los ntawm cov nyhuv parallax, thaum 3D holograms tsim kom muaj kev paub zoo thiab muaj tseeb dua li cov khoom tshwm sim ntab hauv qhov chaw.
4. Kev sib tham thiab kev txav: Txawm hais tias ob qho tib si holograms thiab 3D holograms tuaj yeem sib tham sib, 3D holography feem ntau cuam tshuam nrog kev txav los yog volumetric holograms, qhov twg cov khoom tuaj yeem pom los ntawm txhua sab.
5. Complexity thiab Technology yuav tsum tau: Kev tsim thiab tso saib ntawm 3D holograms yuav tsum tau siv tshuab thiab khoom siv ntau dua piv rau holography tsoos. Ntau lub koob yees duab lossis lasers yog siv los ntes cov ntaub ntawv tsim nyog, thiab cov duab holographic tshwj xeeb yog xav tau rau kev ua si.
Hauv kev xaus, thaum holography thiab 3D holography ob leeg koom nrog kev tsim cov duab peb sab, muaj qhov sib txawv ntawm ob qho tib si. Ib txwm holography captures ib qho kev cuam tshuam tus qauv thiab muaj kev txwv tsis pub saib cov ces kaum, thaum 3D holography suav nrog sau ntau lub ces kaum thiab muab kev paub ntau dua thiab muaj tseeb. Kev nce qib ntawm thev naus laus zis txuas ntxiv thawb cov ciam teb ntawm holography, tso cai rau ntau qhov nyuaj thiab sib tham sib holographic zaub.
