Nheyo uye kukura kwezvinhu zvinoparadzanisa optical

Chinhu cheDiffraction optical imhando yechinhu cheoptical chine simba guru rekupenya, chakavakirwa padzidziso ye diffraction ye light wave uye chinoshandisa dhizaini inobatsirwa nekombuta uye nzira yekugadzira semiconductor chips kuti inyore nhanho kana chimiro chinoenderera mberi che relief pane substrate (kana pamusoro pechinhu che optical chetsika). Zvinhu zveoptical zvakatetepa, zvakapfava, zvidiki muhukuru, zvine simba guru rekupenya, madhigirii akawanda erusununguko, kugadzikana kwakanaka kwekupisa uye hunhu hwakasiyana hwekupararira. Izvo zvikamu zvakakosha zvezvishandiso zvakawanda zve optical. Sezvo diffraction ichigara ichitungamira mukuganhurirwa kwe resolution yepamusoro ye optical system, optics dzechinyakare dzinogara dzichiedza kudzivirira mhedzisiro yakaipa inokonzerwa ne diffraction effect kusvika kuma1960, nekugadzirwa kwakabudirira kwe analog holography ne computer hologram pamwe ne phase diagram zvakakonzera shanduko huru mu concept. Muma1970, kunyangwe tekinoroji ye computer hologram ne phase diagram yaive ichiva yakakwana, zvaive zvichiri kuoma kugadzira zvinhu zve hyperfine structure zvine simba guru rekupenya mu visible uye near infrared wavelengths, nokudaro zvichideredza mashandisirwo anoitwa zvinhu zve optical zvinopenya. Mumakore ekuma1980, boka rekutsvagisa raitungamirwa neWBVeldkamp kubva kuMIT Lincoln Laboratory muUnited States rakatanga kuunza tekinoroji yelithography yekugadzira VLSI mukugadzirwa kwezvikamu zve optical zvinoparadzanisa, uye rakapa pfungwa ye "binary optics". Mushure meizvozvo, nzira dzakasiyana siyana dzekugadzirisa dzinoramba dzichibuda, kusanganisira kugadzirwa kwezvikamu zve optical zvinoparadzanisa zvemhando yepamusoro uye zvinoshanda zvakawanda. Saka zvakasimudzira zvikuru kukura kwezvinhu zvinoparadzanisa.

Kushanda zvakanaka kwechinhu chinopa ruzivo rwe diffractive optical

Kushanda zvakanaka kweDiffraction ndeimwe yezviratidzo zvakakosha zvekuongorora zvinhu zvinopenya zvinopenya uye masisitimu emagetsi anopenya akabatana ane zvinhu zvinopenya zvinopenya. Mushure mekunge chiedza chapfuura nepakati pechinhu chinopenya chinopenya, marongero akawanda eDiffraction anogadzirwa. Kazhinji, chiedza chehurongwa hukuru hweDiffraction chinongotariswa chete. Chiedza chemamwe marongero eDiffraction chinoumba chiedza chakatsauka pamufananidzo wehurongwa hukuru hweDiffraction uye chinoderedza kusiyana kwemufananidzo. Nokudaro, kushanda zvakanaka kweDiffraction kwechinhu chinopenya zvinokanganisa zvakananga kunaka kwemifananidzo yechinhu chinopenya chinopenya.

Kugadzirwa kwezvinhu zvinoparadzanisa optical

Nekuda kwechinhu chinopenya che diffractive optical pamwe ne flexible control wave front, optical system ne device zviri kukura kuita chiedza, miniaturized uye integrated. Kusvika kuma1990, kudzidza nezve diffractive optical elements kwave kuri pamberi pe optical field. Zvikamu izvi zvinogona kushandiswa zvakanyanya mu laser wavefront correction, beam profile forming, beam array generator, optical interconnection, optical parallel calculation, satellite optical communication nezvimwewo.
