Ib 4D hologramyog kev lag luam / kev lag luam shorthand rau:
3D holographic duab + sij hawm / animation + (qee zaum) cov teebmeem ntawm lub cev/sensory
Nws tsis yog qhov tseeb 4th spatial dimension- xwb3D + motion + immersion ntxiv.
1. Nws txhais tau li cas tiag (2 lub ntsiab txhais)
A. Lub ntsiab lus tshawb fawb / technical (precision)
3D: dav × qhov siab × qhov tob (zoo li qub spatial hologram)
4D: 3D + sijhawm (t)→ dynamic, txav 3D hologram (ib "3D yees duab hauv qhov chaw")
Txuas ntxiv hloov kho 3D ntim lub sijhawm
Siv hauv kev tshawb fawb: 4D digital holographic microscopy (nrhiav cov hlwb / cov qauv)
B. Kev lag luam / kev lag luam lub ntsiab lus (qhov koj pom hauv cov xwm txheej)
4D hologram=3D hologram + motion + cov txheej txheem ntxiv:
Tag nrho 360℃/ 270℃parallax(saib ib ncig ntawm qhov khoom)
Animation / txav(lub hologram taug kev, hais lus, hloov pauv)
Feem ntau ntxiv:
Sib tham sib( teb rau kov / gesture)
Cov teebmeem ntawm lub cev: pos huab, cua, ntxhiab, suab (zoo li 4D xinesmas)
Tiag -kev koom ua ke hauv ntiaj teb(hologram tshwm ntawm theem / rooj)
2. Yuav ua li cas nws txawv ntawm "3D hologram ntxuam"
Koj3D hologram ntxuamyog:
POV (tsis pom kev pom) LED zaub
1D kab ntawm LEDs tig los ua lub dav hlau 2D → fake 3D illusion
Tsis muaj tseeb holography(tsis muaj lub teeb yoj cuam tshuam / theem kaw)
A tiag 4D hologram(los yog "volumetric zaub") yog:
Lub teeb tiag tiag- teb / holographic reconstruction
Floats nyob rau hauv cov huab cua nrog tag nrho qhov tob, parallax, motion
Pom los ntawm txhua lub kaum sab xis yam tsis muaj cov hniav spinning
3. Piv txwv ntawm "4D holograms" koj tau pom
Tupac / Michael Jackson Coachella holograms(2012+) → 2D projection on foil ("Pepper's ghost") marketed as 4D
Volumetric qhia(xws li Voxon, Saib iav) → 3D ntim + motion=4D
Sib tham sib 360℃hologram rooj→ touchable txav khoom 3D
4. Cov ntsiab lus yooj yim
3D hologram: Static floating 3D duab
4D hologram: Tsiv / animated 3D hologram(3D + sijhawm)
Hologram fan: Tsis yog qhov hologram tiag tiag -tsuas yog qhov ua kom yuam kev LED
Hauv luv luv:4D=3D uas txav thiab ua ciaj sia nyob hauv qhov chaw.
