Mafirimu ese akajairika e optical anoshandiswa muma liquid crystal projection display systems. Sisitimu yeLCD projection display optical system ine light source (rambi resimbi re halide kana rambi re mercury rine pressure yakakwira), illumination optical system (inosanganisira light system uye polarization conversion system), color separation and color combination optical system, LCD screen, uye projection optical system.
1, AR+HR
Sezvo sisitimu ye liquid crystal projection system inodiwa kuti ishande zvakanaka, kushandiswa kwe reflective film reduction high-efficiency ne high reflective film, kunogona kuita kuti system optical energy ishande kuburikidza ne optical interface yega yega uye mu refractive loss iderere, uye panguva imwe chete inogona kuwedzera miganhu yekudziviswa kwe stray light, kubvisa "mweya wemufananidzo" uye kuvandudza kujeka.
2. Sefa yekucheka yeinfrared, ultraviolet
Sisitimu yekuratidza makristaro emvura (liquid crystal projection system) inowanzo shandiswa kuvandudza kupenya kwechiedza chine simba guru, icho chinoburitsa huwandu hwakawanda hwechiedza che ultraviolet ne infrared mu spectrum. Kushandiswa kwemafirita e infrared, ultraviolet cut-off kunogona kubvisa chiedza che ultraviolet chinokuvadza uye kupisa kwe infrared mu system, kudzivirira kukwegura kwekristaro yemvura, uye kunatsiridza hupenyu hwe system.
3, firimu rekushandura chiedza chakasanganiswa
Makristaro emvura anoda kushandiswa kwechiedza chine polarized light, izvo zvinoda kushandurwa kwechiedza chinobuda kubva kuchiedza chichiita chiedza chine polarized light. Polarizing Beamsplitters (PBS) yakagadzirwa uchishandisa mafirimu e optical inogona kushandura chiedza kuita chiedza chine polarized light.
4. Mafirimu eOptical Akaparadzaniswa neRuvara
Mumasystem ekuratidza magirazi emvura, kupatsanurwa kwemavara uye kugadzirwa kwemavara zvinowanzoitwa nemafirimu e optical. Kuti pave nekuvandudza mhando yesystem, zvinodiwa zvekugadzirwa kwefirimu rekupatsanurwa kwemavara hazvifanirwe kungova nekunyatsorongeka kwenzvimbo ye wavelength uye kuitira kuve nechokwadi chekuti ruvara rwemhando yepamusoro, asiwo zvinoda curve yegirazi re dichroic mukupatsanurwa kwe wavelength ine hunhu hwakakwira, mubhendi re cut-off rine cut-off yakadzika, mubhendi re passband rine transmittance yakakura, diki diki re ripple.
