TASVIRI OPTIKI

TASVIRI OPTIKI, tasvirest, ki dar natijai ba sistemai optiki aftidani nurhoi afkandai obekt yo az on aksshuda hosil megardad.
Istifodai tasviri optiki odatan ba tagyiri miqyosi tasviri predmetho va guzaronidani naqshai onho ba yagon sath (ekran, fotonavor, fotokatod va gayra) aloqamand ast. Odam chizero az on sabab mebinad, ki naqshai on dar pardai shabakiyai chashm aks meyobad.
Tasviri optiki haqiqi va mavhum meshavad. Tasviri optikii haqiqiro dastai nurhoe hosil mekunad, ki dar yak nuqta jam meshavand. Dar hamkorii burishi nurho ekran yo khud fotonavorro guzoshta, dar on tasviri optiki haqiqiro mushohida kardan mumkin ast. Dar digar mavridho nurhoi az sistemai optiki baroyanda parokanda meshavand, ammo agar onhoro khayolan ba tarafi muqobil davom dihem, nurho hamdigarro dar in nuqta meburand. In nuqtaro tasviri mavhumi nuqta (obekt) menomand; on ba nuqtai burishi voqeii nurho muvofiq nameoyad, binobar in tasviri optikii mavhumro dar ekran yo khud fotonavor hosil kardan va ba qayd giriftan imkonnopazir ast.
Ba sifati tasviri optiki az rui taqsimoti zichii energiyai rushnoi dar tasvir baho medihand. Baroi in kontrast (N) nom buzurgiro istifoda mebarand:

dar in jo Emin va Emakh — qimathoi khurdtarin va kalontarini munavvari dar tasviri optikii obekti ozmuni standarti; ba sifati chunin obekt panjaraero qabul mekunand, ki durakhshonii on az rui qonuni sinusoida bo basomadi R tagyir meyobad.
