Nheyo uye kuvandudzwa kwe diffractive optical elements

Diffraction optical element imhando ye optical element ine yakakwira diffraction kunyatsoita, iyo yakavakirwa padiffraction dzidziso yemwenje wave uye inoshandisa komputa-inobatsira dhizaini uye semiconductor chip yekugadzira maitiro kuisa nhanho kana inoenderera yekuyamura chimiro pane substrate (kana pamusoro. yechinyakare optical mudziyo). Diffracted optical elements itete, chiedza, diki muhukuru, ine high diffraction kunyatsoita, madhigirii ekugadzira akawanda erusununguko, kugadzikana kwakanaka kwekupisa uye hunhu hwakasiyana hwekupararira. Izvo zvikamu zvakakosha zvezviridzwa zvakawanda zvemaziso. Sezvo diffraction inogara ichitungamira kune kudzikiswa kwepamusoro resolution ye optical system, echinyakare optics anogara achiedza kudzivirira iyo yakaipa mhedzisiro inokonzerwa ne diffraction mhedzisiro kusvika ma1960s, nekugadzirwa uye nekubudirira kugadzirwa kweanalog holography uye komputa hologram pamwe nechikamu dhayagiramu yakakonzera kuchinja kukuru mupfungwa. Mumakore ekuma1970, kunyangwe tekinoroji yekombuta hologram uye dhiyagiramu yechikamu yaive ichiwedzera uye yakanyanya kukwana, zvaive zvichiri kunetsa kugadzira hyperfine chimiro zvinhu zvine yakakwira diffraction kugona mukuoneka uye padyo neinfrared wavelengths, zvichidzikamisa hunoshanda hwekushandisa kwe diffractive optical elements. . Mumakore ekuma1980, Boka rekutsvagisa rinotungamirwa neWBVeldkamp kubva kuMIT Lincoln Laboratory kuUnited States rakatanga kuunza tekinoroji yekugadzira yeVLSI mukugadzirwa kwezvinhu zvakasiyana-siyana zvemaziso, ndokukurudzira pfungwa ye "binary optics". Mushure mezvo, nzira dzakasiyana-siyana dzekugadzirisa dzinoramba dzichibuda, kusanganisira kugadzirwa kwepamusoro-soro uye multifunctional diffractive optical components. Nokudaro zvakakurudzira zvikuru kugadzirwa kwe diffractive optical elements.

Diffraction kunyatsoshanda kwe diffractive optical element

Diffraction kunyatsoshanda ndeimwe yeakakosha indexes yekuongorora diffractive optical zvinhu uye yakasanganiswa diffractive optical masisitimu ane diffractive optical zvinhu. Mushure mekunge mwenje wapfuura nepakati peiyo diffractive optical element, akawanda diffraction maodha anozogadzirwa. Kazhinji, mwenje chete weiyo huru diffraction order inobhadharwa. Chiedza cheimwe diffraction mirairo ichagadzira mwenje wakarasika pamufananidzo wendege yeiyo huru diffraction order uye kuderedza mutsauko wemufananidzo ndege. Naizvozvo, iyo diffraction inoshanda ye diffractive optical element inokanganisa zvakananga kunaka kwekufungidzira kwe diffractive optical element.

Kuvandudzwa kwe diffractive optical elements

Nekuda kweiyo diffractive optical element uye inochinjika yekudzora wave pamberi, iyo optical sisitimu uye mudziyo uri kusimudzira kupenya, miniaturized uye yakabatanidzwa. Kusvika kuma1990, kudzidza kwe diffractive optical element kwave kumberi kwenzvimbo yekuona. Izvi zvikamu zvinogona kushandiswa zvakanyanya mu laser wavefront kururamisa, danda profiles kuumba, danda array jenareta, optical interconnection, optical parallel calculation, satellite optical kutaurirana nezvimwe.
