Ukulungelelaniswa phakathi kwee-lens zoshishino kunye nemithombo yokukhanya idlala indima ebalulekileyo ekuphuhliseni iinkqubo zokujonga umatshini ophezulu wokusebenza. Ukufezekisa ukusebenza kakuhle kwe-imaging kufuna ulungelelwaniso olubanzi lweeparamitha ze-optical, iimeko zokusingqongileyo, kunye neethagethi zokubona. Oku kulandelayo kuchaza imiba ephambili emininzi yolungelelwaniso olusebenzayo:
I. I-Bancing Aperture kunye nobunzulu boMthombo wokuKhanya
I-aperture (inombolo ye-F) ichaphazela kakhulu ubungakanani bokukhanya okungena kwinkqubo.
Indawo encinci yokuvula (inombolo ephezulu ye-F, umzekelo, i-F / 16) inciphisa ukukhanya kwaye ifuna imbuyekezo ngomthombo wokukhanya ophezulu. Inzuzo yayo ephambili kukunyuka kobunzulu bentsimi, okwenza ukuba ifaneleke kwizicelo ezibandakanya izinto ezinokuphakama okuphawulekayo.
Ngokwahlukileyo, i-aperture enkulu (inombolo ye-F ephantsi, umzekelo, i-F / 2.8) ivumela ukukhanya okungakumbi ukuba kungene, okwenza kube yinto efanelekileyo kwiindawo eziphantsi kokukhanya okanye iimeko zentshukumo zesantya esiphezulu. Nangona kunjalo, ngenxa yobunzulu bomhlaba obunzulu, kubalulekile ukuqinisekisa ukuba ithagethi ihlala ngaphakathi kwinqwelomoya.
II. Isimbo esiKhonelekileyo kunye noLungelelaniso loMthombo wokuKhanya
Iilensi ngokuqhelekileyo zifikelela kwisisombululo esingcono kwimingxuma ephakathi (malunga nendawo enye ukuya kwezimbini zokumisa ezincinci kunowona mkhulu wokuvula). Kolu seto, amandla omthombo wokukhanya kufuneka angqinelane ngokufanelekileyo ukugcina ulungelelwano olufanelekileyo phakathi komlinganiselo wesignali ukuya kwingxolo kunye nolawulo lokungajiki kokukhanya.
III. I-Synergy phakathi koBunzulu beNdawo kunye noMthombo wokukhanya okufanayo
Xa usebenzisa ikroba elincinane, kucetyiswa ukuba lidityaniswe nomthombo wokukhanya omphezulu ofanayo kakhulu (umzekelo, umthombo wokukhanya obonakalisayo). Olu kudibanisa lunceda ukuthintela ukutshatyalaliswa kwendawo okanye ukungabikho, ukuqinisekisa ukuhambelana komfanekiso phantsi kweemeko ezifuna ubunzulu obukhulu bentsimi.
Xa usebenzisa indawo enkulu yokuvula indawo, indawo yokukhanya okanye imithombo yokukhanya egqamileyo ingasetyenziswa ukomeleza umahluko. Nangona kunjalo, ukulungiswa ngononophelo kwe-engile yomthombo wokukhanya kuyafuneka ukunciphisa ukuphazamiseka kokukhanya okulahlekileyo.
IV. ISigqibo esiMatanisa kunye noMthombo wokuKhanya weWavelength
Kwimisebenzi yokukhangela echanekileyo ephezulu, kubalulekile ukukhetha umthombo wokukhanya ohambelana neempawu zempendulo ye-spectral ye-lens. Ngokomzekelo, iilensi zokukhanya ezibonakalayo kufuneka zidibaniswe nemithombo ye-LED emhlophe, ngelixa iilensi ze-infrared kufuneka zisetyenziswe kunye nemithombo ye-laser ye-infrared.
Ukongeza, ubude obukhethiweyo bokukhanya obukhethiweyo kufuneka buthintele iibhendi zokufunxa zelensi yokwambathisa ukuthintela ukulahleka kwamandla kunye nokuphambuka kwechromatic.
V. IziCwangciso zokuSebenza kwiMizobo eDynamic
Kwiimeko zokubona ngesantya esiphezulu, ukudibanisa imbobo enkulu kunye namaxesha amafutshane okuvezwa kudla ngokuba yimfuneko. Kwiimeko ezinjalo, umthombo wokukhanya we-high-frequency pulsed light (umzekelo, isibane se-strobe) sinconywa ukuphelisa ngokufanelekileyo ukufiphala kwentshukumo.
Kusetyenziso oludinga amaxesha okuvezwa amade, umthombo wokukhanya oqhubekayo kufuneka usetyenziswe, kwaye imilinganiselo efana nezihluzo ezibonisa i-polarizing kufuneka ziqwalaselwe ukucinezela uphazamiseko lokukhanya kwe-ambient kunye nokuphucula umgangatho womfanekiso.
