Taw qhia:
Holography tau los ntev heev txij li thaum nws pib hauv 1940s. Nws tau siv thoob plaws ntau yam xws li kos duab, lom zem, thiab kev tshawb fawb. Nrog rau kev nce qib hauv thev naus laus zis, holograms kuj tau hloov zuj zus raws sijhawm. Holographic qhia tau ua rau peb muaj peev xwm cuam tshuam nrog cov khoom siv virtual hauv txoj kev uas peb tsis xav tias yuav ua tau. Txawm li cas los xij, tseem muaj qhov tsis meej pem txog qhov sib txawv ntawm qhov hologram thiab 3D hologram. Hauv kab lus no, peb yuav tshawb txog qhov sib txawv ntawm ob.
** Hologram yog dab tsi?
Ib lub hologram yog ib daim duab peb sab uas tsim los siv qhov tshwm sim ntawm kev cuam tshuam. Nws yog cov duab thaij duab ntawm lub teeb pom kev zoo, tsis yog cov duab tsim los ntawm lub lens. Holograms yog tsim los ntawm kev faib ib lub laser beam rau hauv ob kab: ib tug siv beam thiab ib yam khoom beam. Cov khoom nqaj yog taw qhia ntawm ib qho khoom, thiab qee qhov ntawm lub teeb tawg rov qab mus rau cov khoom siv photosensitive.
Thaum lub teeb siv hluav taws xob yog ci rau cov khoom siv photosensitive, nws tsim cov qauv cuam tshuam. Cov qauv cuam tshuam no muaj tag nrho cov ntaub ntawv hais txog lub teeb uas tau tawg tawm ntawm qhov khoom. Thaum lub hologram illuminated nrog lub teeb laser, cov qauv cuam tshuam ua rau lub teeb tsis sib haum, tsim cov duab peb sab uas zoo li ntab hauv qhov chaw.
Holograms tuaj yeem pom siv lub laser ua lub teeb ci. Lub holography zaj duab xis los yog phaj yuav tsum tau ua kom raug raws li lub laser beam, los yog cov duab yuav tsis tshwm peb-dimensional.
** 3D Hologram yog dab tsi?
Ib tug 3D hologram yog ib tug hologram uas pom los ntawm txhua lub ces kaum. Nws yog tsim los siv ib tug series ntawm ob-dimensional dluab teem nyob rau hauv ib theem zuj zus. Thaum saib ua ke, cov duab no tsim lub illusion ntawm ib qho khoom peb-dimensional.
Muaj ob hom 3D holograms: reflection holograms thiab kis holograms. Reflection holograms yog tsim los ntawm kev xav txog lub teeb laser tawm ntawm daim duab thaij duab thiab mus rau qhov khoom raug kaw. Kev sib kis holograms yog tsim los ntawm kev xa cov kab teeb laser los ntawm daim duab thaij duab thiab mus rau cov khoom raug kaw.
Tsis zoo li ib txwm holograms, 3D holograms tuaj yeem pom los ntawm txhua lub kaum ntse ntse yam tsis tas yuav muaj lub laser ua lub teeb ci. Lawv feem ntau tshwm sim siv cov duab holographic, xws li cov siv hauv cov tsev cia puav pheej thiab kos duab.
** Qhov txawv ntawm Hologram thiab 3D Hologram
1. Hom
Holograms thiab 3D holograms yog ob hom duab holographic. Holograms yog peb-dimensional dluab tsim siv cov qauv cuam tshuam, thaum 3D holograms yog ib theem ntawm ob-dimensional dluab teem los tsim lub illusion ntawm peb-dimensional khoom.
2. Saib
Cov tsoos holograms tsuas yog pom tau siv lub laser ua lub teeb ci, thiab cov holography zaj duab xis lossis phaj yuav tsum tau ua kom raug raws li cov teeb pom kev zoo. Ntawm qhov tod tes, 3D holograms tuaj yeem pom los ntawm txhua lub kaum ntse ntse yam tsis tas yuav muaj lub laser ua lub teeb ci.
3. Zaub
Holograms feem ntau yog tso tawm rau ntawm holography zaj duab xis lossis phaj, thaum 3D holograms raug tso tawm siv holographic zaub, xws li cov siv hauv cov tsev khaws puav pheej science thiab kos duab.
4. Kev tsim
Holograms yog tsim los ntawm kev faib ib lub laser beam rau hauv ob kab: ib tug siv beam thiab ib yam khoom beam. Cov khoom nqaj yog taw qhia ntawm ib qho khoom, thiab qee qhov ntawm lub teeb tawg rov qab mus rau cov khoom siv photosensitive. Ntawm qhov tod tes, 3D holograms yog tsim los ntawm kev noj ib ntu ntawm ob-seem dluab ntawm ib yam khoom thiab npaj lawv ua ntu zus.
5. Kev ntseeg tiag
Traditional holograms yog txwv nyob rau hauv lawv lub peev xwm los realistically sawv cev ib yam khoom. Lawv tsuas tuaj yeem ntes tau lub teeb uas tau tawg tawm ntawm ib qho khoom thaum nws raug kaw, thiab tsis suav nrog kev hloov pauv ntawm ib puag ncig lossis teeb pom kev zoo. 3D holograms, ntawm qhov tod tes, tuaj yeem tsim ntau qhov muaj tseeb sawv cev ntawm ib qho khoom.

Holographic thev naus laus zis tau dhau los ntev txij li nws pib. Holograms thiab 3D holograms tau ua lub luag haujlwm tseem ceeb hauv ntau yam xws li kev tshawb fawb, tshuaj, kos duab, thiab kev lom zem. Holographic cov lus tau tso cai rau peb cuam tshuam nrog cov khoom siv 3D virtual, ua rau nws muaj peev xwm dhau los ua lub ntiaj teb tshiab. Kev nkag siab txog qhov sib txawv ntawm holograms thiab 3D holograms yog qhov tseem ceeb kom txaus siab rau lawv cov txiaj ntsig zoo dua. Txawm hais tias ob hom holograms zoo siab rau lawv tus kheej txoj hauv kev, 3D holograms muaj qhov muaj tseeb dua sawv cev ntawm ib qho khoom.
