Taw qhia
Peb-dimensional (3D) holograms tau ntxim nyiam cov kws tshawb fawb, cov kws ua yeeb yam thiab cov pej xeem thoob plaws ib yam nkaus txij li lawv tsim nyob rau xyoo 1940. Holographic imaging thev naus laus zis tso cai rau lub cim ntawm cov xim tag nrho, peb-seem cov duab uas tshwm sim hauv qhov chaw, muab kev paub zoo uas tau siv hauv kev tshaj tawm, kev lom zem, thiab kev siv txuj ci. Txawm li cas los xij, txawm tias lawv qhov zoo, 3D holograms kuj raug kev txom nyem los ntawm qee qhov tsis zoo, uas kuv yuav tshawb xyuas kom meej hauv kab lus no.
Disadvantage 1: txwv lub kaum sab xis saib
Ib qho ntawm cov teeb meem tseem ceeb ntawm 3D holograms yog tias lawv muab lub kaum sab xis pom. Tsis zoo li cov duab ob-dimensional (2D) cov duab, uas tuaj yeem pom los ntawm txhua lub kaum ntse ntse, 3D holograms tsuas tuaj yeem pom zoo los ntawm ib txoj haujlwm tshwj xeeb rau cov khoom uas tau npaj tseg. Qhov no txhais tau hais tias tus saib txoj hauj lwm yuav tsum tau ua tib zoo tswj, feem ntau xav kom lawv nyob hauv ib cheeb tsam txwv.
Qhov no tuaj yeem ua rau tsis yooj yim rau cov neeg tuaj saib, tshwj xeeb tshaj yog nyob rau hauv kev nthuav qhia pej xeem loj, uas tej zaum yuav muaj ntau tus neeg saib xyuas kom pom cov hologram los ntawm ntau txoj haujlwm. Tsis tas li ntawd, yog tias qhov holographic projection nyob sab nraum zoov, lub hnub ci ci tuaj yeem ua rau nws nyuaj lossis tsis tuaj yeem pom los ntawm qee lub ces kaum.
Qhov tsis zoo 2: Kev daws teeb meem tsawg
Lwm qhov tsis zoo ntawm 3D hologram thev naus laus zis yog qhov kev daws teeb meem tsawg ntawm cov duab tsim. Qhov no yog tshwj xeeb tshaj yog muaj tseeb rau loj-scale holographic zaub. Qhov kev daws teeb meem yog txwv los ntawm tus naj npawb ntawm pixels hauv holographic phaj, uas tuaj yeem ua rau cov duab pixelated lossis qhov muag plooj thaum pom ze.
Qhov kev txwv no tshwj xeeb tshaj yog muaj teeb meem hauv cov ntawv thov xws li kev kuaj mob, qhov twg cov duab daws teeb meem xav tau rau kev kuaj mob kom raug. Lub xeev tam sim no ntawm 3D hologram thev naus laus zis tseem tsis tau nce qib txaus los sib tw cov txheej txheem kho mob ib txwm muaj, uas muab kev daws teeb meem ntau dua.
Disadvantage 3: Tus nqi siab
Lwm qhov tsis zoo ntawm 3D hologram technology yog nws tus nqi siab. Piv rau 2D projection systems, 3D holograms xav tau cov cuab yeej tshwj xeeb thiab cov khoom siv, uas tuaj yeem kim. Cov cuab yeej no suav nrog lasers, iav, beam splitters, thiab cov koob yees duab, uas yog tsim nyog rau kev kaw thiab projecting cov duab holographic. Tsis tas li ntawd, cov ntaub ntawv xav tau los tsim cov phaj holographic yog kim thiab feem ntau nyuaj kom tau txais.
Ntxiv mus, thev naus laus zis tseem nyob rau hauv nws cov me nyuam mos, thiab muaj kev lag luam me me rau nws, uas ua rau tus nqi ntxiv. Yog li ntawd, 3D holography tej zaum yuav kim dhau rau qee cov ntawv thov, uas txwv tsis pub nws siv tau hauv ntau qhov kev lag luam.
Disadvantage 4: Susceptibility rau Vibration thiab Airflow
Lwm qhov kev txwv ntawm 3D hologram projection yog tias nws muaj kev cuam tshuam rau kev vibration thiab airflow. Txawm tias me ntsis vibrations los yog txav tuaj yeem cuam tshuam cov duab holographic thiab ua rau nws tshwm sim distorted los yog wavy. Qhov kev txwv no tuaj yeem ua rau muaj kev ntxhov siab rau cov neeg tuaj saib, uas tuaj yeem ntsib cov duab tsis pom kev lossis qhov muag plooj, uas tuaj yeem cuam tshuam qhov kev paub tsis zoo rau lawv.
Tsis tas li ntawd, airflow kuj tuaj yeem tsim kev cuam tshuam hauv qhov hologram, tshwj xeeb tshaj yog thaum qhov projection tshwm sim sab nraum zoov. Qhov no yog vim huab cua tam sim no tuaj yeem khoov lub teeb laser siv los ua qhov project hologram, tsim cov duab wavy thiab tsis ruaj khov. Txhawm rau txo qhov tsis zoo no, 3D hologram projection yuav tsum tau ua nyob rau hauv ib puag ncig tswj uas muaj kev vibrations tsawg thiab airflow.
Disadvantage 5: Kev siv hluav taws xob
Thaum kawg, 3D hologram tshuab yog lub zog siv zog. Nws yuav tsum muaj lub zog tas li los khiav cov cuab yeej siv, ua haujlwm lub teeb laser, thiab kho cov duab holographic. Qhov kev siv hluav taws xob no tuaj yeem yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum siv cov tshuab loj loj.
Qhov no muaj feem cuam tshuam rau ib puag ncig, vim tias yuav tsum muaj lub zog ntau ntxiv rau lub zog 3D hologram systems, uas tuaj yeem ua rau muaj kev hloov pauv huab cua thiab kev puas tsuaj ib puag ncig. Tsis tas li ntawd, kev siv hluav taws xob siab kuj cuam tshuam tus nqi ntawm kev siv 3D hologram technology, vim tias cov nqi hluav taws xob tuaj yeem ua rau kim kim rau qee qhov kev siv.
Xaus
Txawm hais tias nws cov txiaj ntsig zoo heev, 3D hologram thev naus laus zis kuj raug kev txom nyem los ntawm ntau qhov tsis zoo, suav nrog kev pom lub kaum ntse ntse, kev daws teeb meem tsawg, tus nqi siab, kev cuam tshuam rau kev vibration thiab airflow, thiab kev siv zog siab. Cov kev txwv no tuaj yeem ua rau nws nyuaj rau kev siv thiab siv 3D hologram thev naus laus zis hauv ntau yam kev lag luam thiab kev siv.
Txawm li cas los xij, txawm tias cov teeb meem no, cov kws tshawb fawb thiab cov kws tshawb fawb tau ua haujlwm txuas ntxiv los kov yeej cov teeb meem no thiab ua rau lub xeev ntawm 3D hologram technology. Raws li kev siv thev naus laus zis, nws tuaj yeem nkag mus tau yooj yim dua thiab pheej yig dua, ua rau nws tuaj yeem siv rau hauv ntau qhov chaw thiab siv ntau txoj hauv kev tshiab.
