Ho tloha bofelong ba lilemo tsa bo-1960 le mathoasong a lilemo tsa bo-1970, boholo ba litsamaiso tsa setso tsa ho nka lifoto tsa moeeng li nketsoe sebaka ke li-electro-optical and electronic sensor systems. Le hoja ho nka lifoto ka sefofane ho sebetsa haholo-holo sebakeng sa maqhubu a khanya a bonahalang, lisebelisoa tsa morao-rao tse tsamaisoang ke moea le tse thehiloeng fatše li hlahisa lintlha tsa digital tse koahelang leseli le bonahalang, libaka tsa infrared, thermal infrared le microwave spectral. Mekhoa ea khale ea ho hlalosa pono ea ho nka lifoto ka sefofane e ntse e thusa. Leha ho le joalo, temohisiso e hole e akaretsa mefuta e mengata e fapaneng ea lits'ebetso, ho kenyeletsoa mesebetsi e meng e joalo ka mokhoa oa theory oa thepa e shebiloeng, litekanyo tsa pono ea lintho, le tlhahlobo ea litšoantšo tsa dijithale bakeng sa ho ntšoa ha tlhahisoleseling.

Ka mor'a ho bokella (x, y, z) likhokahano, ho hlophisa lintlha tsena ho ka ntlafatsa katleho ea ho fana le ho sebetsa ha data.
