Tsis muaj leej twg, txawm tias muaj lub vijtsam loj heev , nws tuaj yeem phim cov duab uas tsim los ntawm tus projector. Tshwj xeeb yog tus projector siv ultra-modern laser tshuab hauv nws cov hauj lwm. Qee cov ntsiab lus tseeb txog laser projectors uas koj tuaj yeem kawm tau los ntawm qhov tshooj no.
Laser projector rau tsev
Qee qhov laser projectors hu tau ncaj qha los ntawm cov kab lis kev cai ntawm cathode ray hlab. Raws li nyob rau hauv teeb precursors, cov duab nyob rau hauv laser projectors yog tsim los ntawm sib tov lub rays ntawm peb thawj xim. Qhov no tsuas yog qhov ntawm cov rays nyob rau hauv cov ntaub ntawv no tsis yog cov hluav taws xob hluav taws xob hluav taws xob, tab sis qhov zoo tshaj plaws lasers. Rau 1 thib ob cov nqaj ntawm lub projector "khiav ncig" qhov screen txog 50 npaug, vim li ntawd, cov tib neeg lub hlwb pom cov duab npaj los ntawm nws raws li ib tug tag nrho. Hov, qhov ntse thiab qhov xim ntawm cov duab no yog ua tiav los ntawm txoj kab ke ntawm iav. Tsaug rau qhov no, siv lub laser projector, koj tuaj yeem tau txais ib daim duab zoo heev thiab muaj duab zoo rau txhua qhov chaw, txawm tias tsis tas siv ib qho screen tshwj xeeb. Tab sis vim yog lub cumbersome system, loj zog thiab nqi ntau heev, laser projectors yog tam sim no es kim cov cuab yeej tshaj cov cuab yeej hauv tsev. Piv txwv li, tso tawm rau hauv 2015 los ntawm Epson, ib lub laser projector rau lub tsev ua yeeb yam hauv tsev EH-LS10000 yuav them cov nqi siab tshaj plaws ntawm cov duab siab tshaj plaws hauv cov nqi ntawm $ 10,000. Tus nqi ntawm cov ua haujlwm qauv ntawm laser projectors ranges ntawm 1000 rau 1500 USD. Ua ntej, manufacturers ruaj ntseg zoo ntawm daim duab resulting, yooj yim ntawm kev tswj thiab lub neej kev pab cuam tsawg kawg 20,000 teev.
Holographic laser projector
Holographic projectors yog ib qho tseem ceeb cais ntawm cov tshuab laser. Lawv lub homphiaj yog los tsim cov teebmeem tshwm sim thaum muaj ntau yam qhia, nthuav, thiab lwmyam. Vim muaj qhov nta, cov duab duab puv yuav tawm mus, tsis muaj cov ntsiab lus me me. Tab sis ua tsaug rau xim xim thiab tseem muaj qhov projecting mus rau ib qho nto, cov nyhuv ntau dua qhov kev xav tau. Kuv tuaj yeem siv lub vijtsam holographic mini li cas? Rau hnub tim, muaj ntau ntau yam kiag li tshooj tawm tswv yim rau kev siv laser projectors rau tus qauv tsim ntawm ntau yam xwm txheej. Tab sis txhua tus ntawm lawv nyob rau hauv qhov kawg yog txo mus rau ib tug txawv ua ke ntawm lub nram qab no yam:
- Nqaj yeeb yam. Nws muaj nyob rau hauv qhov projecting lub teeb rays, ntau yam duab cov duab thiab lawv ob peb ua ke nyob rau hauv qhov chaw. Qhov zoo tshaj plaws ntawm cov yeeb yaj duab zoo li no tau los ntawm lawv cov lus qhia los ntawm kev haus luam yeeb thiab huab cua.
- Npo laser yeeb yam (Vijtsam Screen). Nws muaj nyob rau hauv projecting ntau hom duab thaij duab rau txhua lub teeb ntsa (cov phab ntsa ntawm cov tuam tsev, qhov chaw siab roob, cov pa luam yeeb, thiab lwm yam).
Cov xim tsim ntawm lub yeeb yam pom tau yog nyob ntawm qhov xim ntawm lub laser siv nyob rau hauv lub projector. Yog li, feem ntau cov kev xaiv siv nyiaj txiag yog ib lub voj voos uas ua rau lub voj voos ntawm cov xim ntsuab. Qhov no yog vim hais tias qhov teeb meem ntsuab laser yog qhov feem ntau pom rau tib neeg lub qhov muag, thiab yog li ntawd yuav tsum tau tsawg zog rau tiam. Qhov tseem ceeb tshaj plaws yog ib daim duab uas muaj xim laser holographic projector, uas peb lasers ntawm thawj xim (liab, ntsuab, xiav) raug ntsia ntawm qhov nyiaj uas nws tau txais lwm yam xim.
