Iko kurongeka pakati pemaindasitiri lenzi uye masosi emwenje anoita basa rakakosha mukugadzirwa kwepamusoro-inoshanda emuchina masisitimu ekuona. Kuwana optimal imaging performance inoda kurongeka kwakazara kwe optical parameters, mamiriro ezvakatipoteredza, uye zvinotangwa zvekuonekwa. Izvi zvinotevera zvinotarisisa zvakati wandei zvakakosha zvekubatanidza zvinobudirira:
I. Bancing Aperture and Light Source Intensity
Iyo aperture (F-nhamba) inokanganisa zvakanyanya kuwanda kwechiedza chinopinda muhurongwa.
Kaburi kadiki (yepamusoro F-nhamba, semuenzaniso, F/16) inoderedza kupinza kwechiedza uye inoda muripo kuburikidza ne-high-intensity light source. Kunyanya kukosha kwayo kuwedzera kudzika kwemunda, zvichiita kuti ive yakakodzera kune maapplication anosanganisira zvinhu zvine kureba kwakasiyana.
Sezvineiwo, aperture hombe (yakaderera F-nhamba, semuenzaniso, F / 2.8) inobvumira kuwedzera kwechiedza kupinda, zvichiita kuti ive yakanaka kune yakaderera-mwenje nharaunda kana yakakwirira-kumhanya inofamba mamiriro. Nekudaro, nekuda kwekudzika kwayo kwemunda, zvakakosha kuti ive nechokwadi chekuti chinangwa chinoramba chiri mukati meiyo ndege.
II. Optimal Aperture uye Chiedza Source Coordination
Malenzi anowanzo zadzisa kugadziridzwa kwawo kwepakati pepakati (anenge imwe kusvika kuviri inomira idiki pane yakakwira aperture). Pakurongeka uku, kusimba kwemwenje wemwenje kunofanirwa kuenzaniswa zvakakodzera kuchengetedza chiyero chakanaka pakati pechiratidzo-kune-ruzha reshiyo uye yekutarisa aberration control.
III. Synergy Pakati Pakadzika Munda uye Chiedza Source Uniformity
Paunenge uchishandisa kaburi kadiki, zvinokurudzirwa kuibatanidza nechiedza chakafanana chepamusoro (semu, diffuse reflection light source). Musanganiswa uyu unobatsira kudzivirira kuratidzwa kwenzvimbo kana kuratidzwa zvishoma, kuve nechokwadi chekuenderana kwechifananidzo pasi pemamiriro ezvinhu anoda kudzika kwakakura kwemunda.
Paunenge uchishandisa aperture hombe, poindi kana mitsetse yemwenje masosi anogona kushandiswa kuwedzera kumucheto musiyano. Nekudaro, kunyatsogadziriswa kwekona yemwenje sosi inodiwa kuti uderedze kukanganiswa kwechiedza.
IV. Kufananidza Resolution neChiedza Source Wavelength
Pamabasa ekuona epamusoro-soro, zvakakosha kuti usarudze sosi yemwenje inofambirana nehunhu hwekupindura hwema lens. Semuyenzaniso, malenzi emwenje anooneka anofanirwa kupetwa nechena LED masosi, nepo infrared lenzi dzinofanirwa kushandiswa ne infrared laser sources.
Pamusoro pezvo, iyo yakasarudzwa mwenje sosi wavelength inofanirwa kudzivirira mabhendi ekunyudza eiyo lens coating kudzivirira kurasikirwa kwesimba uye chromatic aberration.
V. Maitiro ekufumura eDynamic Scenes
Muzviitiko zvekuonekwa kwepamusoro-soro, kubatanidza buri rakakura nenguva pfupi yekuratidzwa nguva zhinji kunodiwa. Mumamiriro ezvinhu akadaro, high-frequency pulsed light source (semuenzaniso, strobe light) inokurudzirwa kuti ibudirire kubvisa kusvibiswa kwekufamba.
Pazvishandiso zvinoda nguva yakareba yekuvhenekwa, mwenje unoramba uripo unofanirwa kushandiswa, uye matanho akadai semafirita epolarizing anofanirwa kutariswa kudzvanyirira kukanganiswa kwechiedza uye kuwedzera kunaka kwemufananidzo.
