Focal kureba iparameta yakakosha inotara mwero wekusangana kana kupatsanurwa kwemwaranzi yemwenje mumaoptical systems. Iyi parameter inoita basa rakakosha pakuona kuti mufananidzo unogadzirwa sei uye kunaka kwemufananidzo iwoyo. Kana mwaranzi inofambirana ichipfuura nepalenzi yakanangana nekusagumira, inoungana panzvimbo, iyo inotsanangurwa sechinhambwe kubva pakati pekuona kwelenzi kusvika pano. Nzvimbo yepakati ndipo panopindirana maranzi emwenje mushure mekupfuura nemulenzi, achigadzira mufananidzo wakapinza. Kuti uwane mufananidzo wakapinza wechinhu pa infinity, lens inofanira kuiswa mberi kubva kune yakatarisa ndege. Kugadziridzwa uku kunotsanangura kuti nei malenzi mazhinji achireba kana mhete yekutarisa ichitenderedzwa, ichibvumira kunyatsotarisa pazvinhu zviri kure.
Mumidziyo yekuona, the field of view angle (FOV) inoreva kukona kwenzvimbo inooneka yakatorwa nelenzi, nelenzi ichishanda sepamusoro pekona iyi. Iyo FOV kona yakakosha nekuti inosarudza kukura kwenzvimbo inotariswa. Iyo hombe yeFOV angle inoguma mune yakafara ndima yekuona, ichitora yakawanda yenzvimbo yakatenderedza asi ine kuderera kwekukura. Sezvineiwo, kana chinangwa chikapfuura kona iyi, hachizopinda zvizere mundima yekuona, zvichitungamira kune isina kukwana kana kukanganisa mifananidzo. Semuyenzaniso, mukutora mifananidzo yemhuka dzesango, FOV nhete inogona kuguma nekushaikwa kwezvikamu zvemhuka kana zvakaitenderedza, nepo FOV yakafara ichigona kutora zvakawanda zvemukati, zvichideredza mukurumbira wenyaya.
Mumamiriro ezvinhu akajairika, kona yeFOV uye kureba kwefocal zvinoenzana zvakapesana. Hukama uhwu hunoreva kuti hurefu hwefocal hupfupi hunoenderana nemakona makuru eFOV, ukuwo hurefu hwakareba hunoita kuti pave nemakona madiki eFOV. Telephoto lenses, idzo dzine hurefu hwakareba, dzakanakira kutarisa kure uye kupfura mabasa anoda kutora zvinhu zviri kure zvakadzama. Aya malenzi anoshandiswa zvakanyanya mukushandisa kwakasiyana siyana sekuchengetedzeka kwemadhorobha, manejimendi emigwagwa, muganho nemhenderekedzo yekudzivirira yekutarisa, kutora mifananidzo yemhuka dzesango, uye zvinyorwa zvezviitiko zvemitambo. Semuyenzaniso, telephoto lenzi dzakagadzirwa nekugadzirwa neJinyuan Optics, dzine hurefu hwakareba kubva pa30-120mm, 5-50mm, uye 10-50mm, dzinogona kuzadzisa izvi zvinodiwa. Aya malenzi anopa kuita kwakanaka mukutora mifananidzo yakadzama yezvidzidzo zviri kure, zvichiita kuti ive maturusi akakosha kune nyanzvi mundima idzi. Pamusoro pezvo, Jinyuan Optics inopa malenzi madiki ane hurefu hwakareba, senge 1/2.7" 3MP 50mm uye 1/1.8" 5MP 25mm modhi, ayo anosanganisa dhizaini ine simba rekufungidzira.
Sezvineiwo, short-focus lenzis, anozivikanwawo semakona-akafara malenzi, anopa nzvimbo yakafara yekuona nekuda kwemakona awo makuru eFOV. Hunhu uhu hunovaita kuti vanyanyokodzera kutarisa nzvimbo dzakakura dzisina mapofu, sekuchengetedza kuchengetedzwa mumakwere, matura, nhandare dzendege, uye zviteshi. Wide-angle lenses inogona kutora nzvimbo dzakakura, kuve nechokwadi chekuvhara yakazara yenzvimbo inotariswa. Jinyuan Optoelectronics 'yazvino 1/2.5-inch, 1.8mm yakatarisa kureba-yakatarisana lens inoratidzira nzvimbo yakafara yekuona, yakakwirira pixel resolution, uye hunhu husina mvura, izvo pamwe chete zvinobatsira mukuita kwayo kwepamusoro. Iyo yakafara nzvimbo yekuona inobvumira lenzi kutora nzvimbo yakakura mune imwechete furemu, nepo yakakwira pixel resolution inovimbisa kuti ruzivo rwakajeka uye rwakanyatsotsanangurwa. Dhizaini isina mvura inoita kuti ive yakakodzera kushandiswa kwekunze, kunyangwe mumamiriro ekunze akaoma. Nekuda kweizvozvo, lenzi iyi inoshandiswa zvakanyanya mumabhero emusuwo ekuona, masisitimu ekuchengetedza ekuchengetedza, uye makamera emotokari, achipa akavimbika uye emhando yepamusoro ekufungidzira mhinduro dzeakasiyana maapplication.
Muchidimbu, kureba kwefocal uye FOV angles maviri akakosha maparamendi anopesvedzera zvakanyanya kuita kwemaoptical system. Kunzwisisa hukama hwavo uye kusarudza iyo yakakodzera lens mhando zvichienderana nezvinodiwa chaizvo zvinogona kusimudzira zvakanyanya kushanda kwekufungidzira uye kutarisa mabasa mumaindasitiri akasiyana. Kungave kutora zvinhu zviri kure zvine ruzivo rwepamusoro kana kutarisa nzvimbo dzakakura zvizere, sarudzo chaiyo yelens inogona kuita mutsauko wese mukuwana mhedzisiro yakakwana.
