Lintho tse fapaneng tsa optical li na le tšesaane, li bobebe, li nyane ka boholo, li na le ts'ebetso e phahameng ea diffraction, likarolo tse ngata tsa moralo oa tokoloho, botsitso bo botle ba mocheso le litšobotsi tse ikhethang tsa ho hasana. Ke likarolo tsa bohlokoa tsa lisebelisoa tse ngata tsa optical. Kaha diffraction e lula e lebisa moeling oa tharollo e phahameng ea sistimi ea optical, li-optical tsa setso li lula li leka ho qoba litlamorao tse mpe tse bakoang ke phello ea diffraction ho fihlela lilemong tsa bo-1960, ka ho qaptjoa le tlhahiso e atlehileng ea holograph ea analog le hologram ea khomphutha hammoho le setšoantšo sa mohato se bakileng phetoho e kholo ea mohopolo. Lilemong tsa bo-1970, leha thekenoloji ea hologram ea khomphutha le sets'oants'o sa karolo e ne e ntse e tsoela pele ho phethahala, ho ne ho ntse ho le thata ho etsa likarolo tsa sebopeho sa hyperfine tse nang le ts'ebetso e phahameng ea phallo e bonahalang le e haufi le maqhubu a infrared, ka hona ho fokotsa ts'ebeliso e sebetsang ea likarolo tse fapaneng tsa optical. . Lilemong tsa bo-1980, sehlopha sa lipatlisiso se etelletsoeng pele ke WBVeldkamp ho tsoa MIT Lincoln Laboratory United States se ile sa qala ka ho hlahisa theknoloji ea lithography ea tlhahiso ea VLSI tlhahisong ea likarolo tse fapaneng tsa optical, mme sa hlahisa mohopolo oa "binary optics". Ka mor'a moo, mekhoa e mengata e mecha ea ts'ebetso e ntse e tsoela pele ho hlaha, ho kenyelletsa le tlhahiso ea lisebelisoa tsa optical tsa boleng bo phahameng le tse nang le mesebetsi e mengata.

Ho sebetsa hantle ha diffraction ea element ea diffractive optical
Ho sebetsa hantle ha diffraction ke e 'ngoe ea li-index tsa bohlokoa ho lekola likarolo tse fapaneng tsa optical le litsamaiso tse fapaneng tsa optical tse nang le likarolo tse fapaneng tsa optical. Ka mor'a hore leseli le fete ka har'a karolo ea diffractive optical, ho tla hlahisoa litaelo tse ngata tsa diffraction. Ka kakaretso, ke leseli feela la tatellano e ka sehloohong ea diffraction e lebisoang tlhokomelo ho. Leseli la litaelo tse ling tsa diffraction li tla theha leseli le khelohileng sefofaneng sa setšoantšo sa taelo e kholo ea phapano le ho fokotsa phapang ea sefofane sa setšoantšo. Ka hona, katleho ea diffraction ea diffraction optical element e ama ka ho toba boleng ba litšoantšo ba diffraction optical element.

Ka lebaka la "diffractive optical element" le "flexible control wave front", "optical system" le sesebelisoa se ntse se tsoela pele ho ba leseli, le lenyenyane ebile le kopantsoe. Ho fihlela lilemong tsa bo-1990, boithuto ba likarolo tse fapaneng tsa optical e se e le eona e ka pele ho lebaleng la optical. Likarolo tsena li ka sebelisoa haholo ho lokisoa ha maqhubu a maqhubu a laser, ho etsa profil ea beam, jenereithara ea li-beam array, khokahano ea optical, lipalo tsa optical parallel, puisano ea satellite optical joalo-joalo.
