Traditional projectors tsim shading thiab xim nyob rau hauv cov duab projected los ntawm kev txav lub teeb los ntawm ib tug graphical duab uas thaiv ib co lub teeb. Raws li lub teeb dhau los ntawm cov qauv kev cuam tshuam, holographic projectors tsim cov duab los ntawm refraction. Cov duab tsim los ntawm lub teeb ci ci los ntawm cov qauv kev cuam tshuam ncaj nraim (tso tseg rau ntawm lub phaj holographic raws li qhia saum toj no) muaj peb yam - qhov zoo ntawm qhov tab sis tseem tiaj tus. Cov khoom siv iav rotating tuaj yeem siv los ua cov duab 3D tiag tiag.
The technique is based on a high-speed video projector aimed at a rotating platform with a mirror attached, a holographic diffuser, and hardware for decoding digital images, and was first created by researchers at the University of Southern California's Institute for Creative Technologies. 4 Since the mirror spins quickly, it mirrors the picture in all directions, allowing viewers to see it in three dimensions from any perspective.
Lub hauv paus qauv ntawm 3D hologram ntxuam yog 42cm HF-42. Nws txawv nrog rau lwm cov qauv. Nws tsuas muaj ob nplooj, thiab qhov loj yog 42cm nkaus xwb. Nws tuaj yeem muab sib koom ua ke rau hauv cov kiv cua phab ntsa thiab cov duab.
Lub kiv cua tig ntawm 750 kiv puag ncig ib feeb. Peb tau txiav txim siab los ntawm kev thaij duab ntawm tus kiv cua nrog ntau lub shutter ceev los txiav txim siab ntev npaum li cas rau tus kiv cua tig ib qho - plaub ntawm lub kiv puag ncig, uas txaus los tsim cov duab tiav. Peb pom tias ib qho -plaub feem plaub ntawm kiv cua kiv puag ncig siv sijhawm 20 milliseconds, txhais tau tias lub voj voog puv yuav siv 80 milliseconds. Qhov no txhais tau hais tias tus kiv cua yuav muaj peev xwm rov ua yeeb yaj kiab ntawm 50 ntas ib pliag. Txawm li cas los xij, peb pom tsuas yog 15 thav duab ib pliag thaum peb suav cov ntawv tseeb ib ob. Qhov no tau ua tiav los ntawm kev ntes cov yeeb yaj kiab thiab rov ua yeeb yaj kiab ntawm 25 thav duab ib ob nrog cov lej suav txij li xoom mus rau cuaj hauv txhua tus ncej.
Muaj qhov tsis muaj dab tsi rau cov teebmeem AR uas tsis muaj kev cuam tshuam nyob rau lub sijhawm thaum augmented kev muaj tiag apps tau loj hlob hauv qhov chaw. Qhov no tuaj yeem ua tiav yam tsis tas siv cov khoom siv ntawm ib feem ntawm cov neeg soj ntsuam siv lub kiv cua holographic. Cov kiv cua holographic no pab tau rau hauv cov chaw pej xeem xws li khw malls, tshav dav hlau, nqi, thiab lwm lub tsev pej xeem rau kev tshaj tawm lossis kev tawm tswv yim. Tej zaum lawv yuav raug siv los kos xim rau cov khoom, tso saib cov lus ceeb toom, lossis muab cov lus qhia lossis cov ntsiab lus kev nyab xeeb.
